• How do I repartition an SDHC card in Windows?

  - by Peter Mortensen

  How do I repartition an SDHC card (4 GB or more)? Do I need third-part tools or Linux (a live CD solution would be OK)? In Windows' Disk Management the option Delete Partition is dimmed out: I can reformat the card as FAT32, copy files to and from the card and even change the file system to NTFS using the command line command CONVERT, but not repartition it. The article How to Partition an SD Card in Windows XP talks about using "a Windows enabler program" which sound rather dubious to me. I have tried to change from “Optimize for quick removal” to “Optimize for performance”. The option to format as NTFS appeared, but the Delete Partition option is still dimmed out. Platform: Windows XP 64-bit SD card reader: USB 2.0 device, LogiLink® CR0005C Cardreader 3,5' USB 2.0 intern 54-in-1 mit USB Front Kingston 16 GB SDHC card, speed class 4. (It could be formatted as FAT32 and successfully used in a 4 GB ReadyBoost setup (Windows 7).) I have also tried on different versions of Windows and with different cards with the same result: Kingston 4 GB SDHC card, speed class 4 (the one shown in the screenshot) Transcend 2 GB (not marked as SDHC, but SD) Windows 7 32-bit (albeit with a somewhat an older card reader) and Windows XP 32-bit on an EliteBook 8730w

• Upgrading memory in a laptop

  - by ulidtko

  I'm a bit confused about all the memory types and various bus frequencies of modern consumer PCs. Requesting expert help on the subject. So far I'm confident that: I have an Asus X51L laptop with an unknown set of configuration options. The CPU in there supports PAE, so I still have a chance to extend the memory beyond 3GiB; and the upper limit of the system is 8GiB. (?) The laptop has two SODIMM slots, one of which is occupied by a 2GiB bank, and the other one is empty. dmidecode and lshw tools consistently state 533 Mhz frequency of the bank. The last one confuses me the most. I failed to find out characteristics of the northbridge in this laptop, and still can't figure out what DDR2 to seek for. Is it DDR2-1066? Or, rather, PC2-8500/PC2-8600? Wouldn't a DDR2-800 bank harm the system's performance? Which kind of modules should I look up in stores? Update: I have bought a 2 GiB DDR2-800 SODIMM, and it seams that the system can't handle 4 GiB of memory. When installed by itself in either slot, both new and old bank (which btw happens to be marked GDDR2-677) work just perfectly; i.e. any configuration resulting in 2 GiB works. When both banks are installed though (totalling in 4 GiB), the memcheck86 tool produces horrible artifacts and crashes, and system reboots; an Ubuntu system can be started and even logged into a Unity session, but the system reboots too in this case from even a minor RAM load. So it's pretty obvious to me now that this laptop doesn't support 4 GiB of RAM or more.

• VMware Workstation "Power off" and "Suspend" buttons are disabled. What is going on?

  - by Ed Norris

  I've been using an XP image for a few months now with no problems. Recently the power off and resume buttons were disabled and I'm not sure what happened to cause that. In addition, the menu items to do those functions are grayed out (like VM | Power | Power Off) I'm using VMware Workstation 6.5.3 on a Windows 7 64-bit host. The image is Windows XP 32-bit. There is plenty of free space and memory on the host and the CPU is not pegged. I am able to power off the image through its Start menu, but that's a workaround not a fix. Any suggestions? TIA EDIT: Well after manually shutting down the image then closing and reopening the image file (which I've done before) in preparation for reinstalling the tools as suggested below, it looks fine. The power off and suspend buttons are enabled and work. So what do I do with this question now? "Close and restart a few times and it may work" doesn't seem useful...

• How to recover my invisible HD again?

  - by pattulus

  I made this several times now, but this time something bad happened. What I did: I installed Windows 7 at a 32GB partition on my slot 2 HD in my MacPro. Windows 7 made a 105MB partition… I knew this before, but what I didn’t know was that this partition is now on my slot 4 HD. My home folder, my private videos and some other stuff are on this 1TB drive. What I found out so far: I’m currently logged in as another admin since my OS partition as well as the two other HD's aren't harmed. Disk Utility: … only shows the 105MB NTSF partition on this 1TB volume. It isn’t showing my old 1TB partition/ex-HD named "storehouse". Only the partition tab is telling me that there now is a 1TB empty free unpartitioned space. Data Rescue II: … is showing the Volume as it used to be with it's old Name "storehouse". A quick scan and a thorough scan both were done in 1 second which leds me to the conclusion that there's isn’t something deleted at all (» hope!). Data Rescue doesn’t even mention the damn "system reserved" partition. Drive Genius: … also shows the old partition and doesn’t mention the new one. But looking at the info it tells me under "content": FDisk_partition_scheme (instead of Apple_partition_scheme). Well D'oh…. Tech Tools: … doesn’t show the volume, otherwise I'd might have been tempted to press rebuild/repair. What to do next?? I think the best approach is to buy another 1TB HD and let Disk Warrior Clone my old one to it… just to be on the safe side. But what is the best thing to do after this… ???

• KVM Guest Reboot Loop

  - by javano

  I have been pulled into a situation where a KVM server (CentOS 6.2) lost power and upon reboot one of the guests hasn't started up again (XP SP3). I have SSH'ed in and someone must have changed something relating to the hyper visors prior to the power loss, but not rebooted all the guests. This particular guest wouldn't start because it was configured to use /usr/bin/qemu-system-x86_64 which isn't there now (assuming it was before?). I changed it to use /usr/libexec/qemu-kvm as this is what all the other guests on this server seem to be using, and its booting up. Using virt-manager on my local machine I can connect to the display of the XP machine and it gets as far as this screen; http://support.gateway.com/emachines/issues/2-1131285152-01.gif The problem I face now, is that which ever option I choose the machine just reboots. So it's and endless loop. I thought that perhaps a file system error maybe present due to the unclean shutdown. There is an XP SP3 ISO mounted under the guest, which I booted from in an attempt to access the recovery tools, but I don't have the Administrator password! I am out of ideas, and it's turning out to be quite the conundrum. Should I use a 3rd party live CD to test the FS for errors? How else can I trouble shoot these restarts?

• Tables in the SQL Server "master" database, will they cause problems?

  - by pepoluan

  Folks, please be kind on me... I'm just an 'accidental' DBA due to our DBA resigned, so I'm totally a newbie in DBA... You see, I have this application, "ESET Remote Administration Server" (ERAS) that stores its logs and analysis on (originally) a local Access database. The decision was to migrate its database to a SQL Server 2008 R2 machine. ESET (the maker of the software) helpfully provided tools to perform such migration; unfortunately, being the DBA neophyte that I am, I didn't realize that I have to first create my own database (on the SQL Server side) and assign that database as the 'default' database for ERAS' ODBC connection. Now, the migration tool had successfully created a whole bunch of tables inside the "master" database. My questions: Should I leave things be as it is, or should I re-migrate the ERAS database to a different database? If you suggest me perform a re-migration, my plan is to (1) create a new instance, (2) create a new database within the new instance, (3) create a new ODBC System DSN on the ERAS server pointing to the new DB in step 2, (4) use ESET's migration tool to migrate from the current DSN to the new DSN. Do you think I missed a step there? Thanks beforehand for any guidance.

• Nginx flv audio pseudo stream works but video is not loading

  - by sarah

  I am working on a development server for a company & they want nginx webserver to work with. So the requirements for their company is, it should be capable of doing following things i.e hotlink protection, mp4 & flv pseudo stream & secure streaming. However nginx fulfills their requirements and i am configuring their server from past 2 days as i am new to this field so i've only acheived hotlinking prevention in past 2 days. But the problem on which i am stuck is flv pseudo streaming, to make work to mp4 pseudo stream it was just a piece of paper but i am really fuc*ed up with flv pseudo stream. I have converted my flv videos with flvmdi tools to insert many keyframes but the problem is , when i try to seek video from following keyframes that are generated by flvmdi i.e test.flv?start=2681223, video does not load but audio pseudo works fine. So it means no problem with my flv configuration in nginx.conf file. And the forum that i used to compile my nginx-1.2.1 is http://h264.code-shop.com/trac/wiki/Mod-H264-Streaming-Nginx-Version2 & by adding additional module --with-http_flv_module. This forum is really active, hopes i will resolve my problem as soon as you guys will provide me some guide.

• Recover data from quick formatted DVD-R

  - by Andrii Kalytiiuk

  I need to recover data from quick-formatted DVD-R. Please advise a free of charge option (cheap commercial tools will be ok either). Disk was partially recorded with Windows built in disk recorder and recording most likely was not complete. Afterwards I have inserted partially recorded DVD again and on Windows recorder's message box 'How to use this disk?' selected - 'use for CD/DVD player' and data was completely lost - as new recording session was started. Files of photos were recorded on disk. What I have tried so far: DiskInternals CD-DVD recovery - sees 5 jpg files but can't show preview. Tool is commercial - trial version does not allow to recover files. CDCheck - doesn't see any files and reports errors at attempt to scand DVD CD Recovery Toolbox Free - does not even recognize DVD drive ISO Buster - recognizes two files - one MP3 file for 99% of recorded size and one ARC file for about 100 KB MiniTool Power Data Recovery - Free Edition - does not see any files on DVD Stellar Phoenix CD DVD Data Recovery - does not see any files BinaryBiz Virtual Lab - sees DVD disk but needs license to browse content Please advise how is it possible to recover files from DVD.

• rpmbuild gives seg fault

  - by Deepti Jain

  I am trying to build an rpm using the rpmbuild tool. I have source code which build binaries around 30 GB. This software for which I am making the rpm has dozens of executables. When I copy only the binaries of a single executable (Eg. init) my rpm builds successfully. But when I dump the entire build to the rpm, rpmbuild does everything but gives a seg fault in the end. Here is my spec file: # This is a sample spec file for wget %define _topdir /root/mywget %define name source %define release 1 %define version 1.12 %define _builddir /root/mywget/BUILD/glenlivet %define _buildrootdir /root/mywget/BUILDROOT %define _buildroot /root/mywget/BUILDROOT %define _sourcedir /root/mywget/SOURCES BuildRoot: %{_buildroot} Summary: GNU source License: GPL Name: %{name} Version: %{version} Release: %{release} Source: %{name}-%{version}.tar.gz Prefix: /usr Group: Development/Tools %description The GNU sample program downloads files from the Internet using the command-line. %prep %setup -q -n glenlivet %build cd %{_builddir} make all %install rm -rf %{_buildrootdir} mkdir -p %{_buildrootdir}/bin cp -p -r %{_builddir}/build/obj-x64/* %{_buildrootdir}/bin/ %files %defattr(-,root,root) /bin/* If I only copy some of the binaries (let say one utility and its dependent binaries) it works fine. But when I try to copy the entire build, I get a seg fault. I get the seg fault after rpmbuild has executed these sections: %prep %build %install rpmbuild also processes my source file.

• Problem with ubuntu 10.10 running from USB drive

  - by Surjya Narayana Padhi

  I recently downloaded Ubuntu 10.10 and created an USB drive with that. I started to run the Ubuntu from that USB drive. But I am facing so much problem. I am thinking why its not so much easy like Windows to do all my job in ubuntu. Always I get some error message or to install something. This time I am getting the following errors. I am trying to download and install Aircrack-ng. So used the command sudo apt-get install aircrack-ng. But the installation stops with the following error : update-initramfs: deferring update (trigger activated) cp: cannot stat `/vmlinuz': No such file or directory dpkg: error processing bcmwl-kernel-source (--configure): subprocess installed post-installation script returned error exit status 1 Errors were encountered while processing: initramfs-tools bcmwl-kernel-source E: Sub-process /usr/bin/dpkg returned an error code (1) I don't even have the aptitude command installed till now. Are all these errors because of I am running the ubuntu from USB drive? Is there any simple and easy way to go to Ubuntu Software Center and download all the required essentials at one shot and then Aircrack-ng? I could not find the Aircrack-ng in Ubuntu Software Center Can anybody give me detail steps to solve all my problems above. I am frustrated searching for updates and installations. When something works and something does not work. Can anybody suggest me how I should proceed after installing ubuntu to run on a USB drive. So that I can use the OS like Windows. Like software download,wireless driver, sound, video, documents, C:, D: all things should be there. Please somebody help.

• Wifi Works with Android and Windows 8 but not Linux and Win 7

  - by eramm

  Support has told me that our company wide wifi network is setup to support mobile phones only. However it doesn't make sense to me that they can identify a mobile device rather they have setup the Access Point to use a protocol that is only supported on Android and Windows phones. Because the Access Point supports Windows mobile this means that laptops running Windows 8 can also connect to the Access Point (proven). So it stands to reason that since Android is based on Linux there must be a way to connect using Linux as well. iwlist shows IEEE 802.11i/WPA2 Version 1 Group Cipher : TKIP Pairwise Ciphers (2) : TKIP CCMP Authentication Suites (1) : 802.1x WIreshark seems to show that a connection is being made to a website to get a certificate and use a Domain Controller for authentication. Questions: 1) what protocol could they be using that is supported on Win Mobile and Android but not on Win 7 and Linux (Debian) ? 2) what tools can I use to help me discover what protocol i need to support ? I have used iwlist and wireshark but I was not able to glean to much useful information from them. I can post the results if needed. 3) is there an app i can use on my Android phone to help me understand what kind of network it is connecting to ? I can provide more information if you tell me how to get it. I just don't know what I am looking for.

• What Windows app can sort a huge XML file?

  - by Torben Gundtofte-Bruun

  I have some enormous XML-based configuration files, with 125000 lines in them. The problem is that they are auto-generated by the system I use, and "child" tags are in a random order within their respective parent tag. This means that a diff comparison is impossible. I want to recursively sort all tags within a parent tag by the value in name="". Some parent tags only appear once and don't have a name="" parameter; these should be sorted by the tag name itself. Once the files are sorted like this, they can be compared quite easily using normal tools. We are currently using ExamXML which can match unsorted XML files, but it fails because the files are too big. Is there an application that can do this? (Windows much preferred; Linux only as a last resort) I do not want to dive into development or XSLT jobs. I am thinking that someone must have made a simple sorting tool like this already - I just can't find it using Google. Update: With help from this site, I created a small package that I want to share: XML-Sorter_v0.3.zip Update: Follow-up question here.

• Western Digital HDD disappears and reappears in BIOS

  - by tbkn23

  I know many people asked about similar problems, but I have a very specific case where I can't understand what's going on... I have a 3TB Western Digital Caviar Green disk connected in my Desktop, that also has a seagate 1.5TB disk and 2 SSD drives (OCZ and Sandisk). After working fine for quite some time (probably more than a year), suddenly my Caviar Green drive disappeared from windows. I checked the BIOS, and it wasn't there either. I opened my PC, played with the connectors, power, etc, but nothing helped. Even tried switching connectors with those of the 1.5TB disk, and nothing changed, the 1.5TB seagate was there, but the 3TB WD was not. Ok, now for the strange part. I have another desktop at home, so I took out my 3TB drive, connected it there, and it worked fine! I copied the most important files out of it, and then made another attempt in the original desktop. Surprise! It now appeared in the BIOS and worked fine! I even ran the SMART test with the WD tools and it said everything was intact. It doesn't end here. After leaving it overnight in the original desktop, it disappeared again in the morning. I repeated the entire process, connecting it to the second desktop, and there it is again working fine. Now for my question... Whats going on? The disk seems to be appearing on/off in my original Desktop, while other drives there work fine. SMART test says the disk is fine. Any ideas? Is the disk defective and should be replaced? Or maybe there's a problem with the controller in the desktop? I'm using a Gigabyte GA-880GA-UD3H motherboard and tried connecting the drive to both bridges (SATA2 and SATA3 bridges). Thanks EDIT: Power options are set never to turn off hard drives:

• How do I change the default ftp folder in MacOS X 10.6?

  - by Wild_Eep

  I'm running WordPress 2.9.1 from a Mac running 10.6.3. WordPress is installed to the /Library/WebServer/Documents folder. WordPress has a feature called AutoUpdate. Clicking an autoupdate button will download and install updated versions of the WordPress software, or third-party plugin tools. It's a convenient way to keep things up to date. WordPress uses FTP to download the files. I've enabled FTP and set up a user account and opened the requisite ports in my firewall for FTP traffic. This doesn't seem to be enough for my self-hosted installation, though. I'm sure this feature was originally designed for someone who has access to a remote shared webserver, and that it's merely a configuration challenge related to the FTP setup. I feel that if I can adjust the initial directory that the FTP service presents to the AutoUpdate feature, everything else will work properly. So, my question is, how do I adjust what folder is presented when a given user connects to a Mac running 10.6.3 via FTP?

• How to detect/list rogue computers connected to a WIFI network without access to the Wifi Router interface? [migrated]

  - by JJarava

  This is what I believe to be an interesting challenge :) A relative (that leaves a bit too far to go there in person) is complaining that their WIFI/Internet network performance has gone down abysmally lately. She'd like to know if some of the neighbors are using her wifi network to access the internet but she's not too technically savvy. I know that the best way to prevent issues would be to change the Router password, but it's a bit of a PITA having to re-configure all wifi devices... and if the uninvited guest broke the password once, they can do it again... Her wifi router/internet connection is provided by the telco, and remotely managed so she can log-on to their telco account's page and remotely change the router's Wifi password, but doesn't have access to the router status page/config/etc unless she opts out of the telco's remote support and mainteinance service... So, how could she check if there are guests in the wifi with this restrictions and in the most "point and click way"? In this case I'd probably use nmap to look for other devices in the network, but I'm not sure if that's the easiest way to do it. I'm not a wifi expert, so I don't know if there are any wifi-scanning utils that can tell us who's talking to the router... Lastly, she's a Windows user as I guess that'll influence the choice of tools available Any suggestions more than welcome Regards!

• How to connect AD Explorer from Sysinternals to Global Catalog

  - by Oliver

  I'm using the sysinternals AD Explorer quite frequently to search and inspect an Active Directory without any big problems. But now i'd like to connect not only to a single AD Server. Instead i like to inspect the global catalog. If i enter within the AD Explorer connect dialog only the dns name of the machine (e.g. dns.to.domain.controller) that is serving the global catalog i only receive the concrete domain for which it is responsible, but not the whole forest (that's normal behaviour and expected by me). If i'm going to add the default port number (3268) for the global catalog in the form dns.to.domain.controller:3268 AD Explorer will simply crash without any further message. The global catalog itself works as expected under the given name and port number, cause our apache server use exactly this address and port number to authenticate some users. So any hints or tips to access the global catalog out of AD Explorer? Or there are any other nice tools like AD Explorer out there that doesn't have any problems to access the global catalog?

• Windows 2008 R2 file share - any way to "lock it down" outside of a 3rd party app?

  - by TheCleaner

  I have a 3rd party app that "makes a call" to write files to a file share on our network using the currently logged in credentials of the Windows domain user. Meaning the 3rd party app doesn't pass the apps credentials but simply issues a behind the scenes copy command to take a source file specified and copy/move it to the destination "repository" on the file share. The basic premise is that it keeps revisions/approvals for Document Control (think svn/git I guess, similar to this question: Lock down Windows folder to only be updatable by SVN). This all works fine...but here's my issue: I need a way to lock down the file share from being accessed/modified outside of using the 3rd party app (meaning prevent explorer/word/excel/etc from getting to that share). I know I can do the following: make the share a hidden share ($) - this definitely helps. Most users would have zero clue on how to get to such a share. Solves probably 95% of my issue. go one step further and set the "Hidden" attribute on the folders in the hidden share - this would go a little further in that even if a user knows the path to the hidden share like \\server\hidden$ they still won't see folders in that share without changing their explorer options to "show hidden files/folder Any other ideas on how I can lock this down? The users still need modify rights to this share/folders since the 3rd party app relies on their Windows permissions to that location when copying the files into it. I can't really use 3rd party tools to password protect the folder/share without causing the 3rd party app functions to fail.

• Windows based development environment: HyperV, VMWare, or VirtualBox on development machine?

  - by bleepzter

  I am a software engineer with a little bit of an informal "support" functionality... I am trying to figure out what is the best possible approach to employing virtualization technologies into our development process. Since the code we develop is server-centric, testing it often requires a VM with specific software requirements. I used to use VM Ware player (free version) to run my VM's until both of my laptops started exhibiting issues with corrupted windows 7 services and dying hard drives. All leads pointed to VMWare, which by the way seems to be a solid product if you pay for the Workstation edition ($300). On a side note, I have always been a fan of the Windows Server product line. I think it makes for one of the best development environments out there - it is highly scalable, highly reliable, and very efficient. So to be fair I replaced the drives of the laptops and installed Windows Server 2008R2, VS2010 Ultimate SP1, SQL Server 2008R2, TFS Server 2010 and all other tools and API's needed do do my work properly. So now I am stuck with a bunch of VMWare VMs. I don't want to repeat of what happened before, and I certainly don't want to bog down my machine with an inefficient hypervisor or services that are not needed. Futhermore the VMDK hard-disk format used by VMWare is not compatible with the VHD format of Hyper V. It is my understanding that converting from one format to the other can only happen by Microsoft System Center Virtual Machine which I have downloaded from MSDN and ready to install. I guess the question at this point is: Does SCVM run as another service in Windows? Is it a memory hog? What is a better virtualization technology - Hyper-V or Virtual Box in terms of efficiency ease of use and most importantly - memory footprint? (Keep in mind the development environment already has a ton of services running such as TFS Server, SQL Server, IIS, etc...) How would you advise to proceed at this point so that the VMs are still used in the test process? Thanks Martin

• Xen domU mem-set issue

  - by Casper Langemeijer

  I'm running into a problem on my xen 4.0.1 server (debian squeeze) My host has 32G of memory, Domain-0 has 2048 M assigned to it. (scaled down with xm mem-set Domain-0 2048) top in Domain-0 confirms this. I created a virtual machine config file (using xen-tools) with the following options: memory = '512' maxmem = '2048' Both host and guest machines are running the standard 2.6.32-5-xen-amd64 debian kernel. 'xm create' creates a virtual machine with 512MB of memory as expected. Then 'xm mem-set domU 1024' will not expand the memory to 1024MB running 'xm mem-set domU 400' does set the memory to about 400MB Then 'xm mem-set domU 1024' will expands the memory back to 512MB Based on this, you would say that xm ignores the maxmem and silently sets maxmem to 512, but in the output of xm top the MAXMEM column reads 2G. the MEM column will not go over 512M. The output of xm list tells another story, it shows 1024 when I 'xm mem-set domU 1024'. I've googled myself all away around the internet for this issue and found that most people don't scale back Domain-0. I know I've seen a bugreport about the issue I'm experiencing, but can't find it anymore. Does anyone see what I'm doing wrong here? Hmm.. I just upgraded my kernel to the one provided by debian backports. The issue has gone.

• Backup data from RAID 1 disk out of its server

  I'm facing with a pretty easy problem in my opinion. I've extracted a working disk from a RAID1 and I'm looking to copy only data (FS and RAID configuration doesn't matter) into another location (another FS). My problem is I'm not able to mount properly this disk into another linux. I've first looked the partition table : # fdisk -l /dev/sdc Disk /dev/sdc: 640.1 GB, 640135028736 bytes 255 heads, 63 sectors/track, 77825 cylinders, total 1250263728 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/sdc1 63 1249535699 624767818+ fd Linux raid autodetect /dev/sdc2 1249535700 1250017649 240975 fd Linux raid autodetect /dev/sdc3 1250017650 1250258624 120487+ 82 Linux swap / Solaris I've understood I should use dmraid tools. Once installed : # cat /proc/mdstat Personalities : md0 : inactive sdc1[1](S) 624767744 blocks unused devices: <none> And some other informations : # mdadm --examine /dev/sdc1 /dev/sdc1: Magic : a92b4efc Version : 0.90.00 UUID : 8f292f54:7e5aef72:7e5ab5fd:b348fd05 Creation Time : Mon Jun 2 03:39:41 2008 Raid Level : raid1 Used Dev Size : 624767744 (595.82 GiB 639.76 GB) Array Size : 624767744 (595.82 GiB 639.76 GB) Raid Devices : 2 Total Devices : 2 Preferred Minor : 0 Update Time : Tue Feb 7 22:34:59 2012 State : clean Active Devices : 2 Working Devices : 2 Failed Devices : 0 Spare Devices : 0 Checksum : a505b324 - correct Events : 15148 Number Major Minor RaidDevice State this 1 8 1 1 active sync /dev/sda1 0 0 8 17 0 active sync /dev/sdb1 1 1 8 1 1 active sync /dev/sda1 From here, I've tried to mount but I'm not comfortable with dmtools and how it's working. # mount /dev/sdc1 /mnt/sdc1 mount: unknown filesystem type 'linux_raid_member' # mount /dev/md0 /mnt/sdc1 mount: /dev/md0: can't read superblock I've seen some options to alter RAID array with mdadm but I only want to copy data on its filesystem before wiping them... Anyone has a clue ?

• Recover windows cached domain password

  - by theguy

  I have a computer from another small organization that works with our school. It was previously joined to another domain from elsewhere. The organization doesn't have an IT person so they didn't think of what they needed to do about the information on the computer before they moved it to our school. The previous user of the computer is no longer with the organization so no information about the password. The computer has information that needs to be accessed and programs so putting the hard drive on another computer and grabbing the information is a no go as I need the computer itself to be working as well. The computer is running Windows Vista Business Edition and is joined to a domain with a cached profile. The admin accounts are disabled by GPO. I've been asked to see if I could recover the password but running ophcrack gave me no hits on the cached profile. I'm not too familiar with password recovery tools that would work on a cached profile from a domain so I'm looking for answers here. Any other suggestions? Preferably something free as we're a small school and an easy to use liveCD solution like ophcrack would be appreciated.

• Is there a monitoring software suite that will alert me if it has received no activity in a time period?

  - by matt b

  This might be a very basic question, but I am not very familiar with the exact features of Nagios versus Munin versus other monitoring tools. Let's say we have a process that needs to run daily for some very important infrastructure reasons. We've had cases where the process did not run or was otherwise down for a number of days before anyone noticed. I'd like to set up a system that will enable me to easily know when the daily run did not take place for some reason. I can set up this process to send an email on every successful run (or every failed run), but I do not trust that the people receiving this email would notice an absence of an "I'm OK" message. What I am envisioning is some type of "tripwire" service which this V.I.P. (very-important-process) can send a status message to each time it runs, whether successfully or not; and if the "tripwire" service has not received any word from the VIP within a configurable amount of time, it can then send an alert to someone. (The difference between what I envision and the first approach I outlined is a service that sends a message only in abnormal conditions, rather than a service that sends messages each day that the status is normal/OK). Can Nagios be set up to send an alert like this, if it has not heard from a certain service/device/process in N days? Is there another tool out there which does have this feature?

• Associate email account with "Personal Folders" Outlook data file?

  - by TheLQ

  In the process of migrating email servers I've run into an interesting problem: In Outlook 2007 you have the default "Personal Folders" item. This contains the email for the account that was origionally setup with Outlook. My issue is that I have deleted the account associated with that and created an entirely new account. So now I have "Personal Folders" and "[email protected]". However I can't delete "Personal Folders". nor associate "[email protected]" with that PST file. Deleteting it in Outlook (Tools Account Settings Data Files) gave the error "The default data file cannot be removed, because it is your default delivery location. After you have selected a different default delivery location, your current file can be removed." Deleting the PST file itself (outlook.pst) made outlook demand where its default file . would be. So I selected my "[email protected]" PST file and restarted Outlook. Now "Personal Folders" is called "[email protected]", but I still have a duplicate account called this. Which is bad. Worse, my email is associated with the duplicate PST, not the default. How can I associate my email with my default PST or delete the default PST entirely? Luckily I have backu

• Win7 'locking' process/files/folders?

  - by Dynde

  I've had a fair bit problems with sometimes files/folders/processes being 'locked' by Windows. The weird thing is, it's not like the traditional sense, I think, where tools like UnlockIT and wholockme would work. It seems that just giving it a little often helps - making me think it could either be the HDD, the memory, or something in Windows. A scenario: I go into a folder - don't open anything at all, go back up, cut or drag-move the folder to someplace else, it says "Action can't be completed because the folder or a file in it is open in another program". Waiting sometimes 20 seconds sometimes a little longer, and I can move it. Another scenario is deleting a bunch of files in a folder, and it appears that everything is gone, but then suddenly after a few seconds an .exe file pops back up, and I can't delete it. Waiting a few minutes, then pressing refresh and it's gone. I have the strangest feeling that there's a problem with either HDD or memory. I already tried disabling Windows indexing service with no luck. Does anyone have any ideas? EDIT: I should say, that I have a very fast system, 16 GB DDR3 RAM, i7-2600k CPU, SSD main HDD, so I really should not be experiencing any sort of problems, where one might say that it's "reasonable" for the system not to respond right away. Edit2: And I updated SSD firmware a couple months ago, so it shouldn't be bad release FW either
