I recently copied about 1TB of videos from one drive to another. Now it seems like my videos(a lot but not all) are choppy or just end up freezing(mkv files seem to be the ones freezing).Is it possible that the transferring of a large amount of data could have damaged my videos?
View 4 Repliesim running beta 2 of 10.04 x64 and ive noticed a problem where for some reason whenever I download a file it always gets corrupt even though its a 100% complete.
Ive tried using wget instead to download the file and that worked fine
ive removed ubufox package and its now working fine
Is anyone else having this problem?
I wanna be 100% sure that its not my fault and is really a bug before I submit it
I recently installed the latest version of Ubuntu to setup a home media server. Previously, I was running a Windows Home Server. I added a new HD and mounted it during installation. This was ext2. I think mounted my 2 drives that had NTFS partitions on them from the Windows home server and copied all of my files over to the new ext2 partition. Everything looked great. I then re-partitioned by two old Windows Home Server Drives to ext3 partitions to setup a new file system for storage.
This is when the bad news became evident. While all of my .jpg, .mpeg, etc. files are there on my ext2 file system, I can not open them anymore. All programs (IE, paint, windows media player, Itunes, Photoshop, MS Office, etc.) are unable to open files they normally process. Did I somehow lose part of the files (a header, attribute or something) during this copy process?

I've been using Ubuntu on my fileserver for quite a while now, and I've always really had this problem, but I want to finally address it and get it fixed. At seemingly random points (when my fileserver is under stress - typically while I'm writing lots of data to it), my fileserver will crash. It generally completely crashes, not responding to any further file requests or any of my SSH commands, and must be reset hard (typically by flipping the power switch). After such an occasion, I end up with some corrupted files. It seems to corrupt a large array of files (it's not an isolated issue - for example, it corrupts files that were not being accessed anywhere near the time it crashed, including files that had never been accessed during that period of uptime). The files don't get completely smashed, but they're definitely corrupted (artifacts in images, skips in audio and video files, often complete failure of binary files such as virtual hard drives or disc images).
I'm using Ubuntu Server 11.04, but similar issues to this happened for me in 10.04 LTS (in fact, I upgraded to try to solve them). I'm using mdadm to create an 8-drive raid6 array. The drives are 1.5 TB each, mostly Samsung HD154UI, but with a WD drive in there too (sorry, I can't find the model number at the moment). The hard drives themselves appear to be working fine - SMART reports no issues with any of them, mdadm says they're all up, and I have no reason to believe that the drives are at fault here (although I can conduct further tests if necessary). I've posted about this problem before here and here. In these cases, the issues seemed to be with XFS - in fact, I switched from XFS to ext4 on my RAID array because I simply believed XFS to be unstable. Unfortunately, this issue occurs with ext4 as well, so I'm fairly certain it's an mdadm issue. Here is the output of "cat /proc/mdstat", for those interested:

In order to download files from a particular website, I have to include a header containing the text of a cookie, to indicate who I am and that I am properly logged in. So the wget command ends up looking something like:Code:wget --header "Cookie: user=stringofgibbrish" http://url.domain.com/content/porn.zipNow, this does work in the sense that the command does download a file of the right size that has the expected name. But the file does not contain what it should--the .zip files cannot be unzipped, the movies can not be played, etc Do I need some additional option, like the "binary" mode in the old FTP protocols?I tried installing gwget; it is easier to use, but has no way to include the --header stuff, so the downloads never happen in the first place

View 4 Replies View RelatedI have a system with Voyage-Linux (Debian based) as my OS running on a compact flash card. Some files appear to be corrupt on it. Whenever I do a ls,cp,mv,rm command on these files I get the message Stale NFS file handle. I actually had the problem on 2 identical systems. I fixed the first one by attaching the CF card to another linux system and then running e2fsck -f -v /dev/sdb1. It got rid of the bad file.
My problem is I won't be able to do that all the time. I'm gonna have several of these systems in different places and won't have direct access to them, therefore I'm looking for a solution that would work on the system itself. Now running e2fsck on a mounted filesystem seems to be a bad idea from what I read, but I tried anyway and it did not get rid of the file. I tried running tune2fs -c 1 /dev/hda1 and rebooting, which is supposed to run e2fsck after the next boot (not 100% sure here) but that didn't seem to work.

So, onto my question. I kind of messed up my desktop computer trying to remove Ubuntu 8.10. I had installed 8.10 as a dual boot with Windows XP a few years back and now wanted to remove it mainly because of my mother, who can BARELY even turn a computer on. Plus, I can't connect to the internet anyway with Ubuntu (I need the Netzero dial up application in windows, since all I have right now is dial up).
Here's what I did. I downloaded the program "MBRFIX" so I could directly fix the mbr inside of Windows XP, since I don't have an XP recovery disc. I downloaded MBRFIX because I needed to get rid of GRUB. I fixed the mbr, and Windows XP directly booted. All was said and good, except Ubuntu still existed. I poked around on the internet and found something that said for me to use the Ubuntu Live CD and go to gpartition. It said to delete the Ubuntu partitions. So, I tried that, but it said something about unmounting something (I honestly don't remember what it said).
So, I continued following instructions. It said if you couldn't delete the partitions, to go to the terminal and type in "sudo swapoff" and then "sudo umount -a". So I did that. A bunch of stuff popped up in the terminal, mainly stuff that said "cannot unmount". I tried to delete the partitions once again, but that still failed. Finally, I just went back to Windows XP. I went to my computer, manage, and deleted the Ubuntu partitions from there. Finally, Ubuntu was gone! Of course, I wanted my 50GB space back on my XP, but I still had no clue how to go about putting that back. ........
I have a dual boot windows xp/ubuntu64 9.04 rig at home. Ubuntu is installed alongside windows(if i worded that correctly?). well last night i got the infamous error #15. so i popped in the live cd and messed around with grub. well i changed grubs boot to point to h0,5 which is where ubuntu resides and as you can guess i can not boot. i want to change it back to h0,0 or h0,1 however the hard drive is undetected.
I tried windows repair console but same thing cannot detect the drive. I pulled the drive out slipped it in my other machine and still same thing. so my question is how can i go about editing the grub menu.lst if i can't mount the drive?
Maybe i can just install a new grub/mbr? but i cant figure out hot to mount the drive.

I'm running Xubuntu 10.4 and TB 3.0.6 from the repository, and the damndest thing has happened. Thunderbird was working, and then it stopped sending email -- literally from one email to the next. In fact, I didn't even notice it for three hours.
I never got an error message or a timeout or any of the typical problems; rather, I typed the email, hit send, and then it vanished from the screen. I don't get a progress bar on the bottom or a sent message line, and the message doesn't go into the sent folder. I can receive email, and my Internet connection is working.
I tried all the usual stuff -- checking the settings (which I haven't messed with), deleting each of my accounts and putting them back, looking for rogue extensions (again, I didn't add any between the time it worked and it didn't), and uninstalling, purging, reinstalling, etc. I even ran a virus scan.
But it gets weirder. I installed Evolution, and it works fine. And so does Spicebird, which is basically Thunderbird in prettier clothes. So the problem appears to be with the copy of Thunderbird that I have installed, since I haven't heard of anyone else having this problem.
Any thoughts? If this was Windows, I would assume that the software was corrupted or missing a ddl (or whatever), but I've never seen this happen on a Linux system.

View 3 Replies View RelatedI have an Acer Aspire One running NBR 9.10. A few days ago it "went wonky", wouldn't boot and would just seem to start and then shut off before getting to the logon screen. I managed to boot from a USB stick and run check and fix in Gparted. It found a slew of errors in the file system. Unfortunately, it still won't boot, now it just hangs. I assume some of boot files were damaged.
Now I have two problems:
1. Is there a way to repair the damage? Or just wipe the disk and start over?
2. I need to get my e-mail off of the hard drive. I can mount the drive after booting from a USB stick, but the thunderbird directory is locked. Is there a way around this?

I am dual booting a lab of 30 machines in an elementary school. They already have XP installed and I don't want to mess with that. I certainly don't want to have to go to each one with a windows CD to 'repair' each one if this goes wrong.
So i tested on one (installed through PXE) and Ubuntu boots fine but I am getting:
'ntoskrnl.exe is corrupt' errors now. I can't move on until I sort this out.
Yesterday, the file system of my mp3 player went corrupt. So I tried to format it to vfat, which in the past hasn't solved the problem and instead just made another corrupt partition. I have fixed it before by using dereks boot and nuke (dban) and filling it with only zeros so its ready to be repartitioned.
Now this time I tried to save some time by using dd instead of dban.
So I did dd if=/dev/zero of/dev/sdb
The process got interrupted by my system shutting down after about 15 min.

I have earlier downloaded many video and picture files to blank DVD's using Brasero with ubuntu. But now most attempts fail. This might be after upgrading to latest ubuntu, but then again maybe this is not the cause, 'cos maybe once in 6 attempts brasero works ok.

A few months ago I tried to shrink an NTFS partition using gparted and use the free space to install Haiku. However, gparted crashed in the middle of the resize, leading to a corrupt partition table. I tried to solve the problem myself, using testdisk to detect the partitions. However, the fix is not perfect, and it left me with a partition table that goes "outside" of the disk (i.e. the partition table has allocated more sectors than there actually are on the disk to the last partition).
Recently I need to reinstall Ubuntu Natty, but because the partition table is corrupt, the installer on the Ubuntu Natty Live CD (as well as gparted) see the disk as entirely unpartitioned. What is weird is that the Disk Utility (aka palimpsest), fdisk on my current Natty distro (upgraded from Maverick, which I want to replace with a fresh install), and GRUB 2 see the partitions fine (with some errors, such as listing a few trillion TBs of available space, a result of the corrupt partition table).
I am using an Asus U30Jc laptop with a single 500GB HDD. My current setup is supposed to be like this:
/dev/sda1: A hidden FAT32 recovery partition generated by Windows 7, listed as containing Windows Vista by GRUB 2
/dev/sda2: NTFS partition containing Windows 7 (labeled "OS")
/dev/sda3: Extended partition containing "DATA", Ubuntu, swap, and the erroneous trillions of TBs of space
/dev/sda5: NTFS partition containing user data (labeled "DATA")
/dev/sda6: Ext4 partition containing Ubuntu
/dev/sda7: swap partition
(*Though I'm not supposed to have it, and it isn't listed in /dev while running the Live CD, /dev/sda4 exists as a zero-length partition in the output from sfdisk; not sure why)
Currently I've tried the following:
- testdisk, using "deeper search" and writing the partition table back to disk; produced a (usable) partition table that was bad.
- [URL], fsck didn't do much at all, except raise various errors on all partitions except the one containing Natty.
- [URL], tried to substitute the numbers caljohnsmith gave to thegreat with the corresponding values from my run of fdisk -lu, but because caljohnsmith didn't explain where the values came from and what they meant (no offense to him), I was lost; after the last step (setting the end sector on the extended partition to the last cylinder boundary (which I didn't really understand; tell me if you need details on what I did)), gparted went from showing the trillions of TBs of free space as outside all partitions to showing them as inside the extended partition; this also somehow caused the partitions to overlap.(The error parted raises changed from "Error: Can't have a partition outside the disk!" to "Error: Can't have overlapping partitions.
