Hardware :: Data Recovery On HDD - EXT3 File System

Aug 29, 2009

I accidentally formatted a HDD when I meant to format a USB thumb drive. The HDD is a 250GB drive that had about 180GB of data in the EXT3 format. I was actually attempting to make a bootable USB thumb drive with TRK (Trinity Rescue Kit). Kind of funny/ironic to mess up a drive while trying to make a rescue disk. Anyway, as soon as I realized what had happened, I pulled the drive out of the computer to make sure I didn't do anything else stupid to it. I have been searching for some way to recover and haven't really found much. There are a lot of programs to get Windows data back, but I haven't seen anything specific on the EXT3 file system.

Fedora :: Hard Disk Data Recovery Of Ext2 And Ext3

Jul 1, 2010

I am student of MCS and working on final project. I am the user of windows xp. I am new in Linux. I am working on a project that titles "Hard disk data Recovery of ext2 and ext3 in linux". In windows, including dos.h and bios.h header files in program of c language I can send interrupt to bios and access most of the devices like parallel port, hard disks etc. But problem is that there is no bios.h and dos.h files in gcc. Now how can I access my hard drive using c program. How can I call int13h interrupt in linux or there is any other function in the linux to access the hard disk. In fact I want to access sectors of my hard disk using c language program. How can I do it?

General :: Recovering Data From Ext3 Partition With Hardware Errors - Recovery Required On Readonly Filesystem

Jan 10, 2010

I have an external 3.5" USB 250Gb HDD which is showing symptoms of hardware problems (repeated /var/log/messages errors of "reset high speed USB device using ehci_hcd"). This was originally plugged in to my NSLU2 running Debian Etch. I have just installed Ubuntu Desktop 9.10 to a spare Pentium-3M laptop and was hoping to copy the contents of this HDD to a fresh drive. However, I cannot mount it even read-only; mount -o ro /dev/sde3 /mnt/disk fails, and the /var/log/messages error is "recovery required on readonly filesystem", "write access unavailable, cannot proceed". I cannot understand why mounting a disk read-only should require write access. Following advice I googled elsewhere, I tried running mke2fs -n /dev/sde3 to try to list the alternative superblocks - but once again I got the error that the device was read-only. How can I go about accessing the data on this disk?

Nov 3, 2010

I have configured a "Syslog" server on /var directory as a separate ext3 partition - to receive the logs and events from the clients & the firewall as well. The directory needs to grow dynamically as the logs are populated. Is there a way i can make the filesystem grow dynamically as and when the directory is full.

Server :: Mounting Ext3 File System As Ext2 On Slackware With Custom Build Kernel?

May 16, 2010

I just rebuild the kernel for slackware 13, everything works, but root file system which is ext3 is mounted as ext2. Normally I've build ext3, ext4 and so on as modules, not in the kernel... but if I do this, then the kernel mounts the file system as ext2, which is build in the kernel. I also modified rc.modules so I can make sure that ext3,ext4,jbd are loaded, but it doesnt work.

Fedora :: Data Recovery From Drive On Dead FC4 System

Jun 26, 2009

I have Fedora Core 4 PPTP server (poptop) that died (motherboard). I am setting up a replacement system but need to get the data off of the drive from the dead FC4 system. They are just plain text config files. So I removed the drive and mounted it to another system using a USB enclosure. But I can't mount of the root partition, only the boot partition. I have done some Googling and see that the reason is that the / partition is an LVM format. But of course the replacement system already has a /dev/logvol..... type of partition defined. So how can I mount the LVM partition from the dead system on the new system to get the data? Understanding this will be valuable for similar situations in the future.

General :: Recover A Deleted File Using The Ext3 File System?

Jan 10, 2011

I used the ext3 format when I formatted my partition prior to installing Ubuntu10.10. I had accidentally deleted a file and began the process to get it back. It wasn't critical but helpful to recover the file. To make a long story short I ran into to some unexpected road blocks. I tried to use PhotoRec to get the job done but with no success.

I'm just looking down the road in the event I might have to recover something important.If it would be better going back to the Fat32 file system I would rather do it sooner than later. Just as a side note I am dual booting between linux and windows.

CentOS 5 Hardware :: Hard Disk Crash / Data Recovery In RAID1 Webhosting Server

Feb 1, 2011

We have had a hardisk crash in our RAID1 webhosting server running CentOS5 and Plesk. We first realized something was wrong when our main site didn't load but showed MySQL errors. We then found out that the system was in read-only state. Something that also happened the day before yesterday, but we could fix with a FSCK. Then the system worked well til around 18 hours later when it crashed with the same sympoms. So, we rebooted the server and wanted to do a filesystem check again. But the HDD wouldnt even load. It was gone. Unfortunatelly it was not realized that the second disk in the system was also not working any more for some time now. Fortunatelly we had our main site backed up externally though. So we could re-install a fresh box and mounted the two drives to the system. We checked the harddisk. One is practically empty (the older one), the other has almost only files in 'lost + found' but these are all "numbered", no real filenames or so.

Ubuntu :: Corrupted EXT3 File System?

Feb 9, 2011

I am using Ubuntu since release 8.10, but it is first time when i can`t solve problem

when i tried to create new NTFS partition on unallocated disk space with Paragon Partition Manager (damn, that was stupid). Process was aborted with error (later i finally made it with Gparted without problems)

After reboot mine Ubuntu say:

Code:
Errors were found while checking the disk drive for /

Press F to attempt to fix errors, I to ignore, S to skip mounting or M for manual recovery. I pressed "F" but that had help only for a boot and doesn`t really fix error :`(

Later i booted from liveCD and had checked partition (/dev/sdb1; file system - ext3) with gparted (result - aborted fixing process with error) Now i can`t even boot from that partition and even mount it from other linux system.

mine fdisk -l
Code:
/dev/sdb1 * 1 5957 47849568 83 Linux - problematic partition (unmountable)
/dev/sdb2 5958 29983 192988845 7 HPFS/NTFS

[Code]....

PhotoRec recover most of my files, but i need complete partition.

Fedora :: Evaluate The Ext3 File System Performance

Apr 13, 2010

I need evaluate the ext3 file system performance; i need define:

- services provided
- parameters and
- the performance with different parameter values; for example, changin the value of the "data" parameter (journal, ordered, writeback).

I do not know what services ext3 provides. Well, i know intuitively that it provides services to read, write and erase files. But, there are anything more?. Where can i find the API?. Is the ext3 file system POSIX compliant?

General :: Mount A File System (/dev/sdb) As Ext3 (rw,acl,user_xattr)?

Jul 15, 2009

I'm trying to mount a second hard drive as a ext3 (rw_acl,user_xattr). I type the ff.:

# mkfs.ext3 -c /dev/sdb1(it seems to create a file system from this 2nd HD)

then type:

# mount -v /dev/sdb1 / type ext3 (it seems to mount it)

But when I check the ext3 systems with typing:

# mount -t ext3 (to check the list of ext3 devices, it gives me this)
/dev/sda1 on / type ext3 (rw,acl,user_xattr)
/dev/sda2 on /home type ext3 (rw,acl,user_xattr)
/dev/sdb1 on / type ext3 (rw)

How can I make /dev/sdb1 on type ext3 as (rw,acl,user_xattr) as the others?

General :: Mounting An Ext3 File System Destroys Superblocks?

Jun 27, 2010

I have an image of an ext3 file system done with dd. I know that the file system is corrupted but I want to try to recover some files. Whatever I dd it again to the original partition or assign the dd image to a loop device, that's what happens:

- dumpe2fs -h gives me a valid ext3 superblock.

- as I try to mount the device read only, it fails with a bad magic number error.

- executing dumpe2fs -h again gives bad magic number error.

- trying debugfs or fsck with backup superblocks fails the same way.

For me it seems that in spite of mounting the device as read-only, mount command do something wrong with the superblock as before the mount the superblock is correct and it's there.

Hardware :: Change My External Hard Drive's File System From Ext3 To Fat32?

Feb 9, 2010

i needed to change my external hard drive's file system from ext3 to fat32, to use it in windows, which i did the simple way: i shrunk the ext3 partition, made a fat32 partition, copied the files over, removed the ext3 and made the fat32 bigger. unfortunately, while gparted was making the partition larger, my computer shut down. i lost all my files and the partition messed up immediately. i made a new fat32 partition, after deleting the old one, but noticed that gparted was showing 100 gigs already in use (???). so now i have a 300 gb hard drive with only 200 gb i can use; i ran df to make sure gparted wasn't messing up, but indeed it shows the partition as being only 200 gigs in size. i haven't tried making any other kind of partition yet, such as ext3, for fear of losing my files again, and because it wouldn't be permanent anyway, because i need those files in windows and stupid microsoft won't make their OS ext3 compatible.

General :: Ext4 New File System Mounting Compatibility With The Older Ext3 Type?

Sep 7, 2009

How well is the ext4 new file system mounting compatibility with the older ext3 previous Linux installations ? I refer to Ubuntu 9.04 and the new Fedora 11 which have the option to install with the ext4 file format. Will it be better if I install with the older ext3, so that I will be able to mount all other Linux from each other in a multi-boot system ?
