• Alignment requirements: converting basic disk to dynamic disk in order to set up software RAID?

  - by 0xC0000022L

  On Windows 7 x64 Professional I am struggling to convert a basic disk to a dynamic one. Under Disk Management in the MMC the conversion is supposed to be initiated automatically, but it doesn't. My guess: because of using third-party partitioning tools there isn't enough space in front and after the partitions (system-reserved/boot + system volume) to store the required meta-data. When demoting a dynamic disk to a basic disk manually, I noticed that some space seems to be required before and after the partitions. What are the exact alignment requirements that allow the on-board tools in Windows to do the conversion?

• Get exact size in bytes of a disk & partitions in windows

  - by Antonius Bloch

  Hi, I'm using dd (under cygwin) to copy a shadow image of a disk in windows. Shadow copy will only give me a partion, so what I am doing is: 1) using dd to grab the disk header (32k on Win2003) 2) using dd to copy the shadow partition 3) using dd to copy the end of of the disk (8 meg reserved on Win2003) 4) stitch them all together and boot on KVM I need the exact size of all the partitions and non partitioned space on this windows drive. Unfortunately most windows disk tools seem to fudge the numbers a bit, or at least give me a different size than Linux does. I could guess like this 32k + partition size + 8M, but I want to double check. If I make a mistake I could lose data. This is on a remote & live Windows 2003 server so no offline solutions will be helpful. Latest cygwin is installed.

• TabWidget Activity Handling - Does it Create a New Activity EVERY Time?

  - by stormin986

  When a TabWidget is using intents to designate the target Activity for each tab, is there any special handling of those Activities on the Activity Stack outside of the default operation? For Instance, if my app has tabs A, B, and C, and I click them in this order––A, B, A, C, A, B––how will the Activity stack change? My understanding of the default operation, if startActivity() is called each time on the intent, would have the Stack keep loading up new instances of the activities: A, AB, ABA, ABAC, ABACA, ABACAB It's hard to believe that's how it works though... Seems like it would be a waste of resources and could be endless. Can anyone tell me how this will actually work?

• Disable XP disk check using FAT32

  - by mike xie

  Right now I'm using Windows XP and Macintosh on my MacBook Pro via Bootcamp. Sometimes my XP would crash and when I restarted it it would have to go through disk check, although it says I can skip it by pushing a key, but this never worked for me. I did a bit of research online on how to disable disk check and found chkntfs /x c: but when I tried this out in my cmd it said the disk is FAT32 format. I tried to convert my C: drive from FAT32 to NTFS by using convert c: /FS:NTFS but when I tried this it told me to locate my C: drive. I tried to type C: and Bootcamp but couldn't really get past it. I later saw someone said to use this: Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager] "AutoChkTimeOut"=dword:0000000 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager] "BootExecute"=hex(7):61,00,75,00,74,00,6f,00,63,00,68,00,65,00,63,00,6b,00,20,\ 00,61,00,75,00,74,00,6f,00,63,00,68,00,6b,00,20,00,2a,00,00,00,00,00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon] "SFCScan"=dword:00000000 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\MyComputer\cleanuppath] @=hex(2):25,00,53,00,79,00,73,00,74,00,65,00,6d,00,52,00,6f,00,6f,00,74,00,25,\ 00,5c,00,73,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,63,00,6c,00,\ 65,00,61,00,6e,00,6d,00,67,00,72,00,2e,00,65,00,78,00,65,00,20,00,2f,00,44,\ 00,20,00,25,00,63,00,00,00 (Save it as .reg and execute it) I have just tried running it but am not really sure if it did anything (my laptop hasn't crashed yet :) ) Firstly, I am wondering if someone can tell me how to check if that script worked? Secondly, if that script didn't work, does anyone have any solution for these problems? Is there another way to disable disk check or is there another way for me to change my FAT32 to NTFS?

• Ghost activity in android

  - by Ari

  My application works as follow: On start I have some AppStartActivity which does something, finishes itself and starts MainActivity if user is logged in or LoginActivity otherwise. LoginActivity finishes itself and starts MainActivity when user log in successfully. On MainActivity I have SomeActivity from which user can logout. Activity stack for this situation is MainActivity > SomeActivity. It is correct, back button works well. When user click LogOut button there is a problem. I need to show LoginActivity but I don't want to have MainActivity and SomeActivity on activity stack anymore. I could resolve this problem if I wouldn't finish AppStartActivity. I could go back then with flag FLAG_ACTIVITY_CLEAR_TOP and it would work well. But here is a problem with back button. I don't want user to come back to this activity with back button. I want it to exit app instead. UPDATED: Flags FLAG_ACTIVITY_NEW_TASK and FLAG_ACTIVITY_CLEAR_TASK would be best, but I need it working in API level 9.

• Backup all home folders on usb disk and accessibility

  - by PatrickV

  I am using Ubuntu 12.04 and have multiple family members working on it with there own home folder. I have an USB disk and want to use it to backup my home folders. Trying this, I got some questions. When my disk auto mount, it is not visible for each user. It seams to be visible for the user the time I connect the usb disk. I want to create one folder per home on the usb disk to backup the data to. But when I format the disk in EXT4 or FAT for example it is Read Only. How can I format the disk so it is accessible to every user. Best Regards, Patrick

• Gnome Activity Journal does not show recently used files

  - by Nik

  I am running ubuntu 10.10, and installed Gnome Activity Journal. However it does not show any recently used files. I have attached a screenshot below. Please note that gnome activity journal has been installed on the system for quite some time. So it is not that I recently installed and it still has to slowly gather data. Also the zeitgeist-daemon is running in the background. Would reinstalling zeitgeist help solve this problem? If yes could you please provide a ppa where I can find the latest stable release of zeitgeist.

• How do I refresh Disk Utility?

  - by detly

  I do a lot of live system building, which eventually involves imaging a USB drive with the built binary image: dd if=binary.img of=/dev/sdX sync ...where /dev/sdX is a USB drive. As part of my workflow, I like to have Ubuntu's Disk Utility open so I can verify the drive letter and unmount anything that gets mounted automatically. I also use it to create extra partitions for persistence. The trouble is, after writing the image to the device — and even after the sync operation — Disk Utility doesn't show the new partition. It just shows free space. GParted sees it and fdisk sees it. Even after closing and opening Disk Utility, it still shows only free space. If I click "Safe Removal" and physically unplug and replug the USB drive, Disk Utility will then see the partition. Why do I need to remove and re-insert the drive for Disk Utility to see the partitions on it? Can I force Disk Utility to update its information without needing to do this? (using Disk Utility 3.0.2 under Ubuntu 11.10.)

• SMART says disk failure is imminent due to bad blocks, what do I need to do?

  - by flix

  I have on my hard drive 2 OSes: Ubuntu 12.04 and Windows Vista (I keep it just because of school). Everything was OK on both OSes, but one day on Ubuntu I was getting awkward noises from my notebooks' hard drive and then everything stopped and I couldn't do anything. On Windows everything was OK. Every time I boot Ubuntu I can get 5 minutes normal run time, without problems. After that the hard drive sounds crazy and nothing works. I could run S.M.A.R.T tests from a older Ubuntu CD (10.04) from the GUI (Disk Utility, or something like that and from terminal). From the GUI, I got that the DISK FAILURE IS IMMINENT and I have ~700 bad blocks (or broken blocks, I had that test I while ago) on my HDD. From the terminal (I don't remember if it was fsck or a SMART test command) I got that the HDD will fail in under 24 hours. Since then it passed 2-3 weeks. I've tried "badblocks" but after 10 hours it was still running and I had to stop it. Now I have to use cygwin and other alternatives for my Linux apps on Windows. How can I separate the bad blocks from Ubuntu so it wouldn't use them? Please help.

• DPM 2010 "Disk failed or disk not found"

  - by SysAdmin

  I have an HP Proliant ML110 G5 server with Windows server 2008R2 only dedicated for DPM 2010. This server has a limit in HD of 8TB which has already been met. I'm now stuck in this situation where my disk keeps failing "Disk failed or Disk not found" in the disk management. Only after I reboot the system the disk comes back up. Today I was running my monthly tape backup on a certain protection group and the disk failed again while the tape job was running (so the job wasn't completed). This is the description of the error in the alerts: "The disk Disk 1 - Hitachi HDS722020ALA330 SCSI Disk Device cannot be detected or has stopped responding. All subsequent protection activities that use this disk will fail until the disk is brought back online. (ID 3120)". My backup system is becoming useless! I don't think that is a hardware issue (please correct me if I'm wrong) since the HD works fine for a certain period of time which is becoming shorter and shorter. I basically have no more option to fix this problem. I tried to fix any error that was coming up in the event viewer with no luck (included one regarding the SQL2008 compatibility issue). The disk keeps failing! Now I'm only trying to recover/migrate the data from the disk that is having problem but my issue now is that I cannot add any drives to my server since I already got installed the maximum storage capacity 8TB. I thought about 2 simple options. Please tell me what you guys think about it; Unplug one of the 2 storage pool disks (disk0, that one without problem) from the machine and install a new one in order to migrate the data with the Migration tool for DPM. Remove the defective disk (disk1), put back the disk0 and run the synchronization/consistency check on all the groups to recreate replicas and recovery points. Run diskpart.exe and clean up the disk (loosing all data) and hoping that he will work after I sync all the protection groups. Both solutions are not elegant but I have no better options at the moment. Please I need some help. Thanks for your time Angelo

• Dual boot Windows 7 with Windows 8- Dynamic Disk

  - by MeetM

  Its a long explanation. I have a HP Pavilion dm4 notebook. It has pre installed Windows 7 Home Pre. Recently, I tried to install Windows 8 developer preview on my notebook, but while installing, it only allowed me to insatll it on my primary Windows 7 drive I.e. drive C. I had kept 1 empty partition for Windows 8 but when I selectced that option, the next button at the bottom of the window just grey with some error saying Windows cannot boot from this drive....blah blah blah So I googled and found another way of doing it by VHD(virtual hard disk). This seemed to work but on restarting gave me "VHD_BOOT_INITIALIZATION_FAILED" error. After trying all possible ways for around 10 times, I gave up. I noticed that d only thing difference in d tutorials and my notebook is the Disk type. They all had Basic and I have Dynamic. Is that the reason m not able to boot Windows 8? Any suggestions?

• Unmounted disk still spins up regularly

  - by Erik Johansson

  I just added a disk, with partitions but none of them are mounted. The disk will still spin up every now and then. it goes like this: ### disk spins up hdparm -Y /dev/sdb;date /dev/sdb: issuing sleep command 9 feb 2011 23.37.08 CET ### disk spins up hdparm -Y /dev/sdb;date /dev/sdb: issuing sleep command 9 feb 2011 23.46.12 CET Also it always spins up when I shut down the computer. Any tips are welcome, e.g. how can I figure out which process is accessing the disk, are there any daemons doing this? I know it isn't a cron job.

• Can't write to disk

  - by nofacts

  I have seen questions similar to this, but the answers are either beyond me or the situation doesn't quite match mine. Would appreciate some direction. I recently installed Ubuntu 12.04 LTS. The OS is on a disk formatted as ext4. I added another disk to the system and formatted it as W95 FAT 32 (LBA) (0x0c). I did this because I am moving from Windows to Linux, will be needing to go back and forth with data for a while, and might need to move the disk to a Windows machine. There may have been a better format to use, but if so I didn't know any better. I was able to transfer data from an external drive to this FAT32 drive with no problem. Now, though, when I try to create a new folder or write a file to the disk I get a message that the disk is read-only. If I go to the properties, permissions for the disk, for Folder Access it says 'create and delete files'. If I try to change File Access underneath to 'read and write', either nothing happens or I get a message it can't be done. Thank you for any help.

• Windows 7 detects my 1 TB disk as a disk with only 31 MB space

  - by ZelluX

  I've added another 1 TB Western Digital disk on my computer (there is a disk with 250 GB already), and after booting to Windows 7, it recognise the disk, but in the Disk Management panel, it says the disk has only 31 MB TOTAL space, so is what it shows in the EVEREST information. And when I rebooted the computer and entered BIOS, it said the new disk has 0 MB disk capacity. Is there any way to fix this problem?

• Windows software to copy from/to image/disk/partition with offset&compression

  - by Alex131089

  I tried to put everything in the title : I'm looking for a software that is able : to work with image (raw file), partition & whole disk, without distinction to copy whole image or only selected part (let's say .. from 0 to end of last partition, excluding free space for example ; or with start + offset/end system) to handle compression (at least gzip) You recognized, I'm looking for a "dd | gzip" utility with GUI on Windows. The closest tool I found so far is http://www.dubaron.com/diskimage/ but it's a bit old and don't have compression support. Any idea ?

• How do I give Ubuntu 10.10 more space (when installed inside Windows 7 (via wubi))?

  - by Pavitar

  I had installed Ubuntu inside Windows XP but then I formatted XP and installed Windows 7. EDIT1: I used Wubi for the same. I want to know which one of the two will solve my problem? creating a virtual disk or resizing root? Also is resizing root possible as the 4GB ext4 partition is already in a NTFS format Hard Drive partition. At the time of installation I had allocated only 4GB of space to Ubuntu. I want to increase that size as I keep getting a low disk space notification. I have surfed through a lot of similar questions but this is not a duplicate. Because I want to know a little about the file systems. In order to solve my problem,do I have to increase the size of root.disk? Or will it be solved by creating a virtual disk? Also I want to know the difference between creating a virtual disk and just increasing disk space of root.I'm new to Ubuntu so I don't know how the file systems function. EDIT2:I have created a virtual disk of 10gb ,but I'm still getting the same notification.Is there anyway to install all further applications on the virtual disk I created?

• Working with Sub-Optimal Disk Configurations (Making the best of what you’ve got)

  This is the first post in a what will be a series of posts on working with a sub-optimal disk configuration to squeeze as much performance out of it as possible.  You might ask what a Sub-Optimal Disk Configuration?  In this case it is a Dell Powervault MD3000 with 15 Seagate Barracuda ES.2 SAS 1 TB 7.2K RPM disks (Model Number ST31000640SS).  This equates to just under 14TB of raw storage that can configured into a number of RAID configurations.  In this case, the disk array...(read more)

• Disk utility running for a long time

  - by Nik

  I had a spare, old external usb hard disk which stopped working long time back due to improper removal of disk. I tried fixing it in windows (when I did not have ubuntu yet), however I couldn't fix it. So I tried formatting the disk and creating a new partition using the disk utility in ubuntu. However it seems to keep running without any indication of the progress or whatsoever. I have no idea what is happening. I have attached a screenshot below to show what I mean. As you can from the screenshot above it seems to be working on it but no indication on the progress or what it is doing. Any attempt to exit it or do any other task like safe removal or format partition leads to the the following dialog box. What should I do? Wait or restart the computer..???

• Changing Disk Allocation for Ubuntu on Dual-Boot System

  - by OtagoHarbour

  When I first installed Ubuntu, I had a new PC with Windows 7 installed. It was my first installation of Ubuntu so I only allocated 45% of the disk for Ubuntu. Now I find that I have been using Ubuntu exclusively so I would like to change the allocation of the disk so Ubuntu has say 75% of the disk and Win. 7 25%. Is there a way to do this without reformatting the disk. I am using Ubuntu 11.10 with Gnome. Thanks, Peter

• Disk Activity Alert Windows SBS 2003 on Dell PowerEdge 830 with Raid

  - by Ron Whites

  Background: I have a Dell PowerEdge 830 Server running Windows SB Server 2003. It has 4gbs of RAM and a ATA CERC SATA 6CH controller with 3 160gb drives in a Raid 5 configuration. The Problem I am seeing Admin ---"Disk Activity Alert on Server" emails These often occur when disk backups, de-frag or high disk usage is going on. Generally the server isn't over stressed. The Disk Alert emails say in part ... The following disk has low idle time, which may cause slow response time when reading or writing files to the disk. Disk: 0 C: F: D: Review the Disk Transfers/sec and % Idle Time counters for the PhysicalDisk performance object. If the Disk Transfers/sec counter is consistently below 150 while the % Idle Time counter remains very low (close to 0), there may be a problem with the disk driver or hardware. The Questions I have: With what utility can I review the Disk Transfers/sec and Idle Time? It appears there is no utility for that on the server! I think I may need to download a very large (two DVD) Dell "OpenManage" utility to be able to monitor the raid system and see what is a problem is that true?

• Adding third disk as a single disk in a server with an existing RAID1

  - by slowhandsolo

  I've got a ProLiant DL360 G5 server (Fedora 13) with two SAS disks in a hardware RAID 1, working fine. Now I hot plugged another SAS disk. I'd like to configure this new hard disk out of my RAID, as a single non-RAID disk (ex. /dev/sdb). Even after rebooting the server, I can't see the new disk with "fdisk -l". It displays only my hardware RAID, but not the new disk. [root@myserver]# fdisk -l Disco /dev/cciss/c0d0: 300.0 GB, 299966445568 bytes Disposit.

• Strange activity stack behavior when using MapActivity

  - by AndroidDev

  I have the following activity structure in my application A simple "splash screen" activity is started when the application is fired up (let's call it "Splash"). This activity starts the main activity when the user presses a button (I will call it "Main"). Main can in turn start two activities from the menu. The first activity presents a simple form (let's call this one "Form"), the second is a MapActivity that presents a map (it is called "Map"). Main, Form, and Map are declared exactly the same in the manifest: <activity android:name="fully qualified activity class" android:screenOrientation="landscape" android:configChanges="keyboard|keyboardHidden|orientation" > <intent-filter> <action android:name="android.intent.action.DEFAULT" /> <category android:name="android.intent.category.DEFAULT" /> </intent-filter> </activity> When Main is active and I start Form and press "back", Main comes up again. Pressing "back" again brings up "Splash". Nothing strange here. Now comes the strange part: when I am in Main, start Map, and press "back", Main comes up as expected. But pressing "back" again just restarts Main. A second press on "back" is needed to bring me back to Splash! So it seems that starting the Map activity somehow results in Main ending up on the activity stack twice while starting the Form activity does not! Both Form and Map are started like this: startActivity(new Intent(this, MyActivity.class)); I don not catch the back key in any activity. Any clues on what is going on or how to debug this?

• Does pressing Back always cause Activity to finish()?

  - by stormin986

  I've heard that pressing the back button will essentially cause the current Activity to finish(). Is this always the case? Seems like it would be with the way it pops the Activity off the stack. The one situation I'm not so sure about is when the root Activity in a Task has back pressed. I'm currently experiencing a very weird effect, described as follows: On loading my application, the first Activity is for initialization, and once it finishes, it calls my main Activity (a TabActivity). This first init activity has android:noHistory="true" set in the Manifest so pressing Back from my main Activity won't go back to that. It goes to the Launcher. When I click on my App in the Launcher a second time, the initialization activity loads again, and loads the main Activity when done. Almost immediately after, it loads a second instance of my main Activity. But ONLY after the Application has already been run once, and was exited by pressing BACK from the main Activity. It does it every subsequent time until I force quit the app or load a new version from the IDE. Based on this, I am suspecting some kind of Activity instance is lying around and being reused, since it only happens on the second+ time I run the application (and exit with BACK -- using HOME just returns to the last state of the app, no big deal). Anyone have any thoughts??
