  • How to reference other locations in making multi-boot live cd

    - by Nrew
    There is a tool in pen drive linux that allows you to boot directly with multiple iso files. And here is a sample in the menu.lst which allows you to choose which iso file you want to boot. title Fedora 13 find --set-root /Fedora-12-i686-L.iso map /ubuntu-10.04-desktop-i386.iso (0xff) map --hook root (0xff) kernel /casper/vmlinuz file=/cdrom/preseed/ubuntu.seed boot=casper persistent iso-scan/filename=/ubuntu-10.04-desktop-i386.iso splash initrd /casper/initrd.lz I'm just using it on my 8gb flash drive and the location of the iso file is in the flash drive itself. Is it possible to reference other locations. So that I could boot from it, without limitations. because the flash drive can only contain 8gb of data. Is it possible? Anyone here tried this before?

  • WinXP: File Record Segment nnnn is unreadable?

    - by chris
    I'm pretty sure that the drive is toast, except for the fact that this error is only showing up on one partition (it's out of a Dell computer, and has a couple of Dell partitions, which boot and work fine.) I've already purchased another hard drive, and re-installed WinXP, but when I re-connect this drive and reboot, I'm getting thousands of these errors. Is there any chance of recovering any files off this? Should I prevent XP from trying to resolve the problems?

  • How to disable auto insert notification in Windows 7?

    - by White Phoenix
    Alright, here's the problem. My hard drive activity light on my custom built PC is blinking exactly once every second. Microsoft has this to say on the issue: http://support.microsoft.com/kb/138598 There has been discussion on this issue several months ago: Why does my hard drive LED light blink every second? The problem seems to stem from primarily Windows 7 polling the CD-ROM/DVD drive every second to see if something is inserted. The Windows 7 users in the thread that was linked in the superuser question, https://social.technet.microsoft.com/Forums/fi-FI/w7itprohardware/thread/4f6f63b3-4b58-4154-9298-1566100f9d00, have confirmed that this IS a known issue with Windows 7. Some people point at the motherboard circuitry causing the CD-ROM and SATA activity to both be linked to that hard drive activity, but whatever the case, the temporary solution seems to be to disable the CD/DVD-ROM drive in Device Manager. In fact, disabling the CD/DVD-ROM does stop the blinking, but of course this solution is counterproductive, because I shouldn't have to entirely disable a device to fix this problem. I've done the following suggestions in that thread: Change the autorun registry entry to 0 Completely disable autoplay in the autoplay control panel Disable autoplay in the Local Group Policy Editor. None of these stop the blinking from happening - apparently these solutions work for both XP and Vista, but it seems to be different in Windows 7. So I'm wondering if anyone has found out how to completely disable the polling in Windows 7, or if this will just have to be an issue we will have to deal with. There's no option to disable the auto insert notification when you go to the device within device manager (there was in XP), so I got no idea where this option is hidden, or if there's a registry key entry I could change to stop the polling. Anyone have any idea?

  • Does a 3ware "ECC-ERROR" matter on a JBOD when I have ZFS?

    - by Stefan Lasiewski
    I have a FreeBSD 8.x machine running ZFS and with a 3ware 9690SA controller. The 3ware controller shows an ECC-ERROR with one of the disks: //host> /c0 show VPort Status Unit Size Type Phy Encl-Slot Model ------------------------------------------------------------------------------ p0 OK u0 279.39 GB SAS 0 - SEAGATE ST3300657SS p1 OK u0 279.39 GB SAS 1 - SEAGATE ST3300657SS p2 OK u1 931.51 GB SAS 2 - SEAGATE ST31000640SS p3 ECC-ERROR u2 931.51 GB SAS 3 - SEAGATE ST31000640SS p4 OK u3 931.51 GB SAS 4 - SEAGATE ST31000640SS /c0 show events shows no ECC errors in it's recent history. ZFS does not currently detect any errors. zpool status says No known data errors My question: Is this ECC-ERROR something that I need to be concerned about? According to the 3ware CLI 9.5.2 Manual, an ECC-ERROR means that the 3ware controller caught a read-error for one or more sectors on this drive. This sometimes occurs when a RAID array is recovering from a failed disk. I believe that ECC-ERRORS can also be detected when the 3ware Controller verifies each disk. None of the drives have failed and thus there was no drive rebuild, so I assume that 3ware discovered a bad sector when it ran it's weekly auto-verify scan of the disks. Is this a safe assumption? According to our logs, ZFS has not detected any bad sectors on this drive. ZFS can work around read errors -- if ZFS detects a bad sector on the drive, it will simply mark that sector as bad and never use it again. From the ZFS perspective one bad sector isn't a big deal, although it might indicate that the drive is starting to go bad.

  • Should I use SSD Caching on non bootable HD?

    - by Onema
    I have an asus 9p79x pro which allows me to do SSD Caching. I have a 256 GB SSD drive that I use an my primary boot drive, and I have a 1 TB disk where I put most of my games, music, videos, dowloads, pictures, etc. I also have an extra 64 GB SSD Drive that I'm currently not using. I thought it would be a good idea to use it as my 1 TB disk cache and improve the load time of games and programs that are installed on the 1 TB disk; but will this work correctly? It seems from all that I have read online about this board that it is used to cache a boot drive. Any thoughts? Thank you

  • Are Motherboards for the Acer Aspire One AOA150 Netbook Compatible with the AOA110?

    - by Mindstormscreator
    I have an Acer Aspire One ZG5 AOA110-1588 netbook, and the motherboard doesn't have a port for a SATA 2.5 inch hard drive; it only supports this slow 8GB SSD type drive. Through research I've discovered that the AOA150 motherboards do have a SATA slot, and the bottom plate of these laptops have an appropriate protrusion for the drive to fit in (for example, compare this to this). The AOA110 and AOA150 models are very similar in appearance and specs. I've even seen tutorials that involve soldering a SATA connector onto the AOA110's motherboard, essentially creating an AOA150 motherboard (right?) So, could I just swap out the motherboard in my netbook with the MBS0506001? (I'd post another link to the actual board but can't because of the spam prevention...) I assume I would also need to purchase and replace the bottom cover with a larger one and possibly get a hard drive caddy as well...? Thanks!

  • Raid HDD Boot up

    - by user234695
    My server is Power Edge 1950 running server 2008 32Bit, using 3 Physical SAS HDD as a Virtual 2 Disk configured for RAID5, with partition of C drive as OS and D drive as Data. Planning to format and install Server 2008 R2 64Bit so I insert a New Physical disk and configured as RAID5 and clone the C drive and D drive to the new hard disk. Now I need to test that the new hard disk is able to boot windows and work as expected. How do I test, I am not able to boot the windows by choosing the new harddisk, the bios show only the existing HDD, not the new one. Also, if I remove the old three hard disk, and leave the new harddisk and then am I able to boot the device, if I do this does my existing RAID5 configuration and data on the hard disk still remain.

  • Using client certificates with wget

    - by Doc
    I cannot get wget to use the client certificates. The documentation speaks about using the --certificate flag. The use of the certificate flag is clear, I set it to use the PEM version of the client certificate. But when I connect I get the following error: HTTP request sent, awaiting response... Read error (error:14094410:SSL routines: SSL3_READ_BYTES:sslv3 alert handshake failure; error:140940E5:SSL routines:SSL3_ READ_BYTES:ssl handshake failure) in headers. Giving up. ssl handshake failure means the client did not supply a correct client cert. Still the client cert I use, works in a browser. Note: When I disable client authentication on the server, wget can connect. Note: The use of curl is suggested, but I'd like to avoid the switch.

  • Moving my bcd from HDD to SSD - Windows 7

    - by lelouch
    I have windows 7 installed on my SSD, but the /boot/ and bootmgr are on my hard-drive. I want to move them to my SSD for faster booting times. So i figured that I can fix the problem using the Windows startup repair tool. I made a bootable windows 7 flash drive, and ran Windows startup repair. However, it exits with an error. I also can't see my OS in the list of installed OSs. I then tried fixing via the command prompt with bootrec /fixmbr, bootrec /fixboot, bootrec /rebuildbcd. Bootrec /rebuildbcd finds the OS, but gives me the error "The requested system device cannot be found" when i try fixing it. Does anyone know why this is failing? I read somewhere that the Windows Repair environment doesn't support a flash drive, which is why I'm getting that error. Is this true? Unforunately my dvd drive is playing up so I can't use it to test this.

  • Win7 Command Prompt drives not available

    - by jmerrill
    I have the opposite problem compared to the author of this question: Hard drive access denied from Windows Explorer (but works from command prompt as Admin) I can see all the drive letters for a particular server in Windows Explorer, and can navigate through them exactly as would be expected. The drive letters are displayed in Explorer in parens to the right of the path info -- finalpathportion (\\server\otherpathportions) (driveletter:) e.g. jmerrill (\\server\users) (H:) But the drive letters are not usable in a "Run as Administrator" command prompt. They have worked in the past, but I have since rebooted. I thought that perhaps I had to start a new command prompt having visited them in Explorer -- but that did not help. "net use" in the command prompt shows Unavailable H: \\server\users\jmerrill Microsoft Windows Network with similar info for the other drives. I can do net use h: /d net use h: \\server\users\jmerrill for each drive, and get the letters to be available in the command prompt. It is perhaps obvious that I don't think that it should be necessary to do that. Does anyone have any ideas?

  • Is it possible to have a wireless in-house NAS with wireless data transfer rates of equivalent to SATA speeds?

    - by techaddict
    Basically I would like to know, if it is possible to set up an NAS in my house to be accessed wirelessly, that can reach equivalent real-life data transfer speeds to USB 3.0 or an internal SATA hard drive. I have been wanting to do this for some time ( a couple of years now). Basically, this is what I want to do: Plug in a number of hard drives in an array, somewhere in my house, to be left plugged in and never have to be monitored. Ideally several terabytes. Whenever I am home, to have my computer and laptop configured to automatically find the NAS, as easy as plugging in an external hard drive - except completely wirelessly. Data transfer needs to be as seamless and quick as having added another internal hard drive in my laptop. Moreover, data should be able to accessed without having to copy it over - I should be able to wirelessly access the NAS and browse files, and open files directly from the NAS. For example, say I wanted to open a video - I should be able to play the video that is located on the NAS, directly from the NAS, completely wirelessly. If I wanted to open a .pdf file, I should be able to open it and read it directly from the NAS, as if it were located on my physical internal hard drive. Cost is important as well. Please tell me what equipment I need for this to be possible. I know you geniuses out there who can tell me if this is possible.

  • hardlinking takes a lot of space

    - by mr_schlomo
    I made an rsync incremental backup script for my server that will copy a MySQL database backup and a specified folder path to a remote server. Here's the code on Github. Code excerpt from lines 53-57: ############### Create most current hand link echo "Creating most current hard link on backup server $most_recent_backup_link" ssh $remote_backup_server rm -rf ${most_recent_backup_link} ssh $remote_backup_server cp -alv ${remote_backup_folder}/backup-${backup_folder_name}/ ${most_recent_backup_link} I'm having a problem with creating the most current hard links on the backup server (lines 53-57 in the program). Everything works, and rsync only copies about 1-2MB of data. But the hard link copy process uses about 30MB of data. I get a huge laundry list of files that haven't changed and the only ones that have changed are very small in size. Normally this isn't a problem, but when you backup every hour, the backup should be as small as possible. For example, the last backup I did, rsync transferred 1.3MB. But the backup directory grew 35MB. Why are the hard links taking up so much hard drive space?

  • Disable Acer eRecovery system

    - by Joel Coehoorn
    The meat of this question is that I'm looking for a way to either require a password before using a recovery partition or "break" the recovery partition (specifically, Acer eRecovery) in a way that I can later "unbreak" only by booting normally into windows first. Here's the full details: I have a set of new Acer Veriton n260g machines in a computer lab. A lot work went into setting up this lab to work well - for example, Office 2007 and other programs needed by the students were installed, all windows updates are applied, and a default desktop is setup. All in all it's several hours work to fully set up one machine. Unfortunately, I don't currently have the ability to easily image these machines, and even if I did I would want to avoid downtime even while an image is restored. Therefore, I've taken steps to lock them down — namely DeepFreeze and a bios password to prevent booting from anywhere but the frozen hard drive. DeepFreeze is an amazing product — as long as you boot from the frozen hard drive, there is no way to actually make permanent changes to that hard drive. Anything you do is wiped after the machine restarts. It lets me give students the leeway to do what they want on lab computers without worrying about them breaking something. The problem is that even with the bios locked and set to only boot from the hard drive, these Acers still have a simple way to choose a different boot source: shut them down and put a paper click in a little hole at the top while you turn it on again. This puts them into the "Acer eRecovery" mode. This by itself is no big deal — you can still power cycle with no impact. But if you then click through the menu to reset the machine (we're now past the point of curiosity and on to intent) it will wipe the hard drive and restore it to the original state. Of course, a few students have already figured this out and reset a couple machines. That's unfortunate, but inevitable. I don't want to destroy the ability to do this entirely (which I could by repartitioning the drives to remove the recovery partition) but I would like a way to require a password first, or "break" the recovery system in a way that I can "unbreak" only if I first un-freeze the hard drive in DeepFreeze. Any ideas?

  • USB to USB CD ROM emulator

    - by JohnnyLambada
    I'm wondering if anyone knows of a CDROM emulator that runs on Linux. I want to emulate this configuration: [CDROM DRIVE]----USB CABLE----[COMPUTER UNDER TEST] Where [COMPUTER UNDER TEST] is a computer that boots from a physical CD inserted into the [CDROM DRIVE]. Only instead of the [CDROM DRIVE] I want the following configuration: [CD IMAGE BUILD MACHINE]-----USB CABLE-----[COMPUTER UNDER TEST]. I want to build an ISO image on the [CD IMAGE BUILD MACHINE] and have some sort of USB CDROM emulator running on it to serve up the ISO image to the [COMPUTER UNDER TEST] as though it was talking to the [CDROM DRIVE]. Does this exist? If it does, I can't find it. I want to do this so I can test out bootable CDs without burning a lot of coasters.

  • Restoring the exact state of a linux install to a different laptop with different sized drives and other hardware

    - by user259774
    I have an IBM running a Manjaro install that has already been used and settled into, with packages installed, browser profiles, etc, etc. The drive is 60gb, and it has a swap partition and an ext4 root partition. I need to move this profile to a Toshiba computer with a 320gb drive. How should I go about this? My inclination would be to shut down the toshiba, boot a live linux system, dd the whole 60gb drive to a file, boot the toshiba to a live system, then dd the file to its 320gb drive. Would this work? I know that it wouldn't with windows, but I believe this is an artificially imposed limitation from Microsoft. Is this correct, or is Linux similarly limited? If not, how could I go about this? Would clonezilla work, or would the hardware disparities prevent it from working?

  • Best SQL Server Configuration with this hardware.

    - by DavidStein
    I just received my new SQL Server from Dell. The server will be serve approximately 15 OLTP databases which average 10GB in size. Here are the basic specs: Dell PowerEdge R510 with up to 12 Hot Swap HDDs,LED Intel Xeon E5649 2.53GHz, 12M Cache, 5.86 GT/s QPI, 6 core (Quantity of 2) 48GB Memory (6x8GB), 1333MHz Dual Ranked RDIMMs for 2 Processors, Optimized PERC H700 Integrated RAID Controller, 1GB NV Cache 300GB 15K RPM SA SCSI 6Gbps 3.5in Hotplug Hard Drive (Quantity of 4) 600GB 15K RPM SA SCSI 6Gbps 3.5in Hotplug Hard Drive (Quantity of 6) My first thought was to use 3 arrays. OS - Raid 1 - (2)300GB T-Log - Raid 1 (2)300GB DB - Raid 5 (5) 600GB Backup - (1) 600GB - non-raided. However, I could also do the following after purchasing one more drive for backup. OS and T-Log - Raid 10 - (4)300GB DB - Raid 10 (6)600GB The hard drive space is not an issue as the databases are not that large. I'm just trying to optimize the speed of the applications using these databases. So, what would you guys recommend?

  • How to install Win7 over top of WinXP partition?

    - by Zeno
    I have a 2TB hard drive with 2 partitions on it, one a C drive for WinXP and another for extra space. I have a Win7 Pro install DVD and I have formatted that C drive via the DVD; it is now a blank "Primary" partition. I attempted to go through the Win7 setup and install it on that partition, but it's giving me an error: Setup unable to create new system partition or locate existing system partition. See setup log files for more info Googling around leads me to believe the entire drive has to be "cleaned" (diskpart) but that would wipe the entire other non-OS partition and I need to keep that data. How can I install Win7 on this blank partition without losing data on the other partition?

  • Can Time Capsule backup its own network share or can Time Machine be setup to do so?

    - by Sam Brightman
    Apple's Time Capsule can act as both a backup drive and a network shared drive at the same time. Can it backup its own data to incremental backups? I can't find this information anywhere. I've not used Time Machine so I don't know if it can be configured to backup shared drives (independently of whether Time Capsule has the option). I would like this to be a feasible way of freeing up some storage on an older MacBook Air by keeping large media such as photos archived on the drive like you would a USB external drive. But having the only copy accessible throughout the house and not backed up would make me nervous. I like the idea of having a good router, network storage and backup in one box, although obviously it's safer to backup the Capsule itself to USB occasionally too. Other solutions to this are of course welcome if this is not possible.
