• You need to format the disk in drive

  - by Sab

  I was copying some files over to my external hard disk and suddenly a message popped up saying that some file was open and it could not continue.It asks me whether I want to cancel the operation and I said cancel(The other operation was continue.) After that whenever I plug in the usb into the same computer it does not work. It keeps saying that I need to format the disk to continue. Luckily for me it opened on another computer and am backing up all my data. But now I am wondering why exactly this happened. Is it that the hard disk is weak. Also as an addon I currently use http://www.dtidata.com/windowssurfacescanner/ program to check for bad sectors. Is this the recommended way or is there some other better more reliable way to check if my hard disk is failing? Also could the above problem be because the hard disk is failing? If not why does it happen.Even if the hard disk is interrupted in the middle of a read write cycle doesnt there exist error handling code to enable gracefull recovery?

• Can't access my accelerated hard disk from msdos after installing linux on ssd cache

  - by Chibueze Opata

  I mistakenly installed Linux Mint on my ssd (forgot my PC actually came with one), when it detected a ~31GiB disk that it wanted to install to, I was a bit confused since I had brought out 30Gb in my primary disk for it, but I clicked continue. After installation, I tried to boot back into my Windows and it brought out some Intel Raid Disk Utility stuff saying I should disable acceleration on a disk something couldn't be found, I canceled it but whatever I tried, recovery tools, setups etc, I couldn't just access the drive which was apparently using the SSD as cache. Since then I've been stuck. I tried setting the 'raid' flag to the disk from 'gParted', still I couldn't. I tried the diskraid utility from windows recover disk, it said it couldn't detect any raid, diskpart sees the partition but doesn't see the volume, when I remove the raid flag, it sees the volume as one of raw type, and I can't access anything. I can however mount the drive from terminal in Mint and access my files, but I don't have any backup media at the moment so I can do a factory re-install. Please how do I go about solving the issue, precisely I would like to know how to boot into the drive again. Thanks!

• Missing Data on VMWare Virtual Disk

  - by Lachlan McDonald

  Evening all, I've got a considerable problem I'm hoping to get some resolution on. I had two VMWare 6.5 virtual machines, one running Ubuntu 9.10 and the other Ubuntu 10.04. I used 9.10 as a testing server, so I could install a LAMP environment to prepare some code. Over the months I took a number of snapshots of this VM just in case something went wrong, and did a full copy of the entire VM a month ago. I created the 10.04 VM when Lucid Lynx launched so I could continue development on a fresh install. To get the files over, I simply added the 9.10 virtual disk into the 10.04 VM, grabbed some of the files I needed, and dismounted it. Unknown to me at the time, the changes to the 9.04 virtual disk meant that I could no longer boot it with the 9.10 VM. I'd always get the "The parent virtual disk has been modified since the child was created." error. I decided this was a good time to backup all the critical files, but now whenever I open the 9.04 disk to get the data it isn't in the same state as it was earlier. My question is; is it possible when I'm mounting the virtual disk that I'm not seeing the most recent snapshot, or in my blundering, have I lost the virtual disk. Cheers

• virtual disk image - file or partition

  - by tylerl

  I'm looking at the differences between using a file versus a partition to store a virtual disk image in VM use. The common knowledge is that partition-based images are faster than file-based images because of a decreased overhead. It makes sense, but I've never seen any actual numbers. My own testing bears out a different result. When I benchmark a direct-to-partition virtual disk, then format that same partition with ext4, create a virtual disk image stored on that ext4 filesystem, and then benchmark that, I see no speedup at all for the direct-to-partition virtual disk. Instead on some systems the file-based image is even faster (possibly due to host OS caching or something like that). This test was repeated many times on many systems, with fairly consistent results. So perhaps throwing out the performance justification, is it still considered better to use a partition rather than a virtual disk image? Is there some other reason why direct partition access is better than image files? Or perhaps is there some reason to go the other way around? Perhaps an advantage in one of the virtual disk file formats that you don't get with raw partition images?

• How can I recover a Fedora 12 installation that is showing signs of disk errors?

  - by Bob Cross

  I am currently overseas (i.e., very far from my normal library of tools) and my primary machine that would normally act as the data server in the performance test that we're trying to run is failing to boot to Fedora 12 properly. This is a machine that, as of yesterday, was booting fine. However, this morning, very strange portions of the boot process were complaining with messages such as "unexpected 0x0 in rpcbind" and "bad file descriptor" (I don't have the error in front of me - scavenged a windows installation to get onto serverfault). Eventually, the boot hung for a long time at the NFS service and then brought up what looked like the KDE login screen but neither the mouse nor keyboard functioned. In olden days, I would try to get to a point where I could manage to run fsck and pray that the bad sectors would come back into alignment just long enough for me to scrape the critical data off of the machine. However, now that we live in the future, it seems like our options in situations like this should be a little more varied. Is there a way to recover a Fedora 12 installation with bad disk sectors that won't boot properly? For completeness, I am comfortable working with bootable recovery distros-on-CD and such but I don't know which one is likely to work best with modern Fedora. In the absence of guidance, I'm frantically torrenting the Fedora 12 Live CD and DVD, hoping to try rescue mode before tomorrow morning.

• raid 0 data recovery?

  - by Fred

  HI All, I have two identical seagate 7200.9 500Gb drives confiured as a RAID 0 spanned disk in windows. One of the drives has lost power and wont spin up at all. I know this normally means death for the data on both drives but i have a cunning plan.. DISK 1 - NO POWER RAID 0 DISK DISK 2 - FULLY FUNCTIONAL RAID 0 DISK DISK 3 - FULLY FUNCTIONAL SPARE DISK Copy the working drive (disk 2) data to a third 500GB DISK (disk 3), remove the logic board from the working disk (disk 2) and replace it with the non working logic board on the broken drive (disk 1) , then hopefully recreate the RAID 0 with disk 1 and disk 3, just long enough to get the data off it. Hope this makes sense, here are my questions: Windows disk manager atm recognises disk 2 but wont let me access it in anyway, therefore copying the data off it (or getting a disk image) cant be done in windows. Does anyone know of any software (in linux or self booting) that would allow me to access this disk? Anyone know of any software that will recreate the spanned drive off two disk images Am i missing any key information that means i definitely shouldn't even bother starting this, i know its a long shot anyway but its worth a try unless i definitely cant do it. The irritating thing is that i am sure its a logic board failure on disk 1 as it simply wont power up at all, suddenly no signs of life, so i am sure the data is intact! Any help would be really appreciated! Thanks

• Win2008: Boot from mirrored dynamic disk fails!

  - by Daniel Marschall

  Hello. I am using Windows Server 2008 R2 Datacenter and I got two 1.5TB S-ATA2 hard disks installed and I want to make a soft raid. (I do know the disadvantages of softraid vs. hardraid) I have following partitions on Disk 0: (1) Microsoft Reserved 100 MB (dynamic), created during setup (2) System Partition 100 GB (dynamic) (3) Data partition, 1.2TB (dynamic) I already mirrored these contents to Disk 1. Its contents are: (1) System partition mirror, 100 GB (dynamic) (2) Data partition, 1.2 TB mirror (dynamic) (3) Unusued 100 MB (dynamic) -- is from "MSR" of Disk 0, created during setup. Since data and system partition are mirrored, I expect that my system works if disk 0 would fail. But it doesn't. If I force booting on disk 0: Works (I get the 2 bootloader screen) If I force booting on disk 1 (F8 for BBS), nothing happens. I got a blank black screen with the blinking caret. I already made disk1/partition1 active with diskpart, but it still does not boot from this drive. Please help. Both partitions are in "MBR" partition style. They look equal, except the missing "MSR" partition at the partition beginning (which seems to be not relevant to booting). Regards Daniel Marschall

• Disk Drive not working

  - by user287681

  The CD/DVD drive on my sisters' (I'm helping her shift from Win. XP (now officially deprecated by Microsoft) to Ubuntu) system. Now, it may end up being a failed attempt, all together (Almost the whole last year (when she's been on XP) the disk drive hasn't (not even powering on) been working.), I just want to make sure I've explored every remote possibility. Because I figure, "Huh, now that I've got Ubuntu running, instead of XP, that (just) might make a difference.". I have tried using the sudo lshw command in the terminal, to (seemingly) no avil, but, who knows, you might be able to make something out of it.

• Disk mounter applet for Unity?

  - by sdaau

  Well - just because I cannot find this asked anywhere else on the net - is there something like a "Disk Mounter" applet for Unity interface, or are there any alternatives? (By 'alternatives' I mean: I wouldn't mind doubleclicking an icon, and have what used to be a toolbar applet start up as a separate window; as long as don't have to grapple with mount command lines, and filesystem arguments and such) Thanks, Cheers!

• Resize the disk space of Ubuntu 12.04

  - by lara

  I m using Wubi 12.04. While I installed, the disk size was 18 GB. Now I m almost running out the space. But I have enough space in Windows drive in which I installed Wubi. I tried to increase the size of Ubuntu from this link https://help.ubuntu.com/community/ResizeandDuplicateWubiDisk But It gives the msg wubi-resize.sh: The new size (5 GB) isn't sufficient to hold your wubi-resize.sh: existing install (18 GB) plus a freespace buffer What should I do?

• Seriousness of a "Smart" disk error. How long will it last?

  - by Workshop Alex

  I have an 1 TB data disk and the bios and Windows are reporting a "Smart" error. At least, I get a Smart event but it doesn't indicate how serious the failure could be. My system is about 6 months old, including the disk so the warranty will cover the damage. Unfortunately, I lack a second disk of 1 TB in size which I can use to make a full backup. The most important data on this disk is safe, but there's a lot of work data which can be regenerated but this would cost a lot of time. So I ordered an USB disk of 1 TB which will arrive in three days. By then I can make a full backup of the data and afterwards, it can crash. But will the disk live that long? (Well, I won't use the PC as long as I can't make a backup.) How serious is such a Smart event? I know it's serious enough to have it replaced, but will it live for another week or could it die any moment?Update: I purchased an 1 TB external disk and spent most of the day making a backup of the 1 TB disk. It survived that. I then received a new disk, since it was still under warranty and replaced the hard disk. Then I had to spend most of a day again to put back the backup. I need to send back the faulty disk and now have an additional external disk, which could always be practical. :-) The Smart Error report did not cause any failures on the original disk. I won't advise to ignore these warnings, but the disk still has enough life in it to last a few more days. (Just make sure you have a good back-up.) And oh, the horror of having to make a complete backup such a huge disk. :-) If your data is important, make sure you have something that supports incremental backups and lots of space. (In my case, the data wasn't very important, just practical to have on-disk together.)

• Graphical disk surface check tool?

  - by sbergeron

  I need a program that can scan my hard drive for read and write errors so I can partition around them. I REALLY don't do well with numbers but if I can have something that shows an output like the graphical display on gparted that would be perfect. I know a lot of people would recommend replacing the disk but right now I can't as I NEED this laptop for school and can't wait for a hard drive to arrive (I have ordered one, yes, but I don't expect it to arrive for another couple weeks as I only figured out afterwards they still have to manufacture it)

• I get an "serious errors while checking the disk drives for /boot" error while booting

  - by Vaios Argiropoulos

  I have just set up my new system by creating three partitions on a whole hard disk (/boot,/home,swap and /(root)) .I saw this article and now i am getting those errors and the system provide me with some options (I to ignore, S to skip mounting or M for manual recovery). I am forced to choose skip mounting because i don't know what manual recovery is. Despite the error i get i think that the system boots ok because i can use the system but this error is very annoying.

• "No caching mode page present" when USB flash disk attached

  - by evgeny9

  When attaching a USB flash disk (NTFS formatted) to a laptop with Ubuntu Server 12.04 on board, I get following messages: [ 3572.355603] sd 2:0:0:0: [sdb] No Caching mode page present [ 3572.355640] sd 2:0:0:0: [sdb] Assuming drive cache: write through [ 3572.361599] sd 2:0:0:0: [sdb] No Caching mode page present [ 3572.361636] sd 2:0:0:0: [sdb] Assuming drive cache: write through I get them right in the terminal, so that I should press Ctrl+C to proceed with working (entering commands). Is it normal or do I have to setup Caching mode somehow? Thank you.

• javascript/jquery input fields cleanup

  - by user271619

  I've created a few input fields, that I am cleaning up as the user types. So, I'm using a keystroke detection event, like .keyup() It's all working very well, but I do notice one thing that's rather annoying for the users. While the script is cleaning the data as they type, their cursor is being sent to the end of the input field. So, if you want to edit the middle of the value, you're cursor immediately goes to the end of the box. Does anyone know of a way to maintain the cursor's current position inside the input field? I'm not holding my breath, but I thought I'd ask. Here's the cleanup code I'm using: $(".pricing").keyup(function(){ // clean up anything non-numeric **var itemprice = $("#itemprice").val().replace(/[^0-9\.]+/g, '');** // return the cleaner value back to the input field **$("#itemprice").val(itemprice);** });

• Simple VM That allows booting from folder or disk

  - by None

  I was wondering if there was a very simple and free virtual machine that would allow you to boot from a folder or disk image that couldn't damage my hard disk. I am using a MacBook and am looking into operating system programming. I found a tutorial on the internet that looked promising (http://www.viralpatel.net/taj/tutorial/hello_world_bootloader.php). I want to try this but using a VM instead of actually booting from a disk. If I made a folder or disk image containing the boot.bin file and wanted to try the OS I made (while booting from a folder or disk image, not a disk), is there a VM that would let me do it? I have no previous experience with virtual machines. I also want to be sure my hard disk would not be damaged.

• Invoke a cleanup method for java user thread, when JVM stops the thread

  - by user309281

  Hi All I have J2SE application running in linux. I have stop application script in which i am doing kill of the J2SE pid. This J2SE application has 6 infinitely running user threads,which will be polling for some specific records in backend DB. When this java pid is killed, I need to perform some cleanup operations for each of the long running thread, like connecting to DB and set status of some transactions which are in-progress to empty. Is there a way to write a method in each of the thread, which will be called when the thread is going to be stopped, by JVM.

• Need data on disk drive management by OS: getting base I/O unit size, “sync” option, Direct Memory A

  - by Richard T

  Hello All, I want to ensure I have done all I can to configure a system's disks for serious database use. The three areas I know of (any others?) to be concerned about are: I/O size: the database engine and disk's native size should either match, or the database's native I/O size should be a multiple of the disk's native I/O size. Disks that are capable of Direct Memory Access (eg. IDE) should be configured for it. When a disk says it has written data persistently, it must be so! No keeping it in cache and lying about it. I have been looking for information on how to ensure these are so for CENTOS and Ubuntu, but can't seem to find anything at all! I want to be able to check these things and change them if needed. Any and all input appreciated.
