ac_dispatcher Posted November 9, 2004 Report Share Posted November 9, 2004 OK I messed up big time. Here is the skinny if anyone has something else I can try please help. fstab /dev/hda1 - /mnt/windows <fat32> /dev/hda2 - / <reiserfs> /dev/hda3 - swap /dev/hda5 -/mnt/data (22GB) <ext3> /dev/hda6 - /mnt/linux (DistroHo partition) <ext3> OK here is what I tried to do. Boot to windows and started up Partition Magic. Tried to: delete /dev/hda4 expand the logical drive (hda4) to incompass the freespace (hda4) enlarge hda5 to addon the 500mg of hda4 create hda7 for swap Set it all up and hit "OK" AN ERROR HAPPENED When I first booted hda4 was gone and their was free space in the front of hda5. hda5 said unknown file format. I was able via a MDK disk1 to reset hda4 as it was (primary partion). But /dev/hda5 still lists itself as unknown file format. When I boot to a MDK disk it lists it as ext2 (its ext3). When I try to mount it: arora acdispatcher # mount -t ext3 /dev/hda5 /mnt/data mount: wrong fs type, bad option, bad superblock on /dev/hda5, or too many mounted file systems OK next we try: arora acdispatcher # e2fsck /dev/hda5 e2fsck 1.35 (28-Feb-2004) Couldn't find ext2 superblock, trying backup blocks... e2fsck: Bad magic number in super-block while trying to open /dev/hda5 The superblock could not be read or does not describe a correct ext2 filesystem. If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock: e2fsck -b 8193 <device> OK now Im real worried Did I say that my backup is corrupt too? go go google: http://edseek.com/archives/2004/02/25/ext3...block-recovery/ http://forums.scotsnewsletter.com/index.ph...topic=503&st=50 They gave me good ideas. Here is what I tried: arora acdispatcher # mke2fs -n /dev/hda5 mke2fs 1.35 (28-Feb-2004) Filesystem label= OS type: Linux Block size=4096 (log=2) Fragment size=4096 (log=2) 2709120 inodes, 5407872 blocks 270393 blocks (5.00%) reserved for the super user First data block=0 166 block groups 32768 blocks per group, 32768 fragments per group 16320 inodes per group Superblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208, 4096000 Ok got some backup superblocks (I think) so we try: arora acdispatcher # e2fsck -b 32768 /dev/hda5 e2fsck 1.35 (28-Feb-2004) e2fsck: Bad magic number in super-block while trying to open /dev/hda5 The superblock could not be read or does not describe a correct ext2 filesystem. If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock: e2fsck -b 8193 <device> I did that for all the above block numbers. Im stuck. Ive tried Partgui, QTparted, Partition Magic wont even come up anymore. Then in terminal I found this: arora acdispatcher # partgui Session management error: Authentication Rejected, reason : None of the authentication protocols specified are supported and host-based authentication failed Warning: Unable to align partition properly. This probably means that another partitioning tool generated an incorrect partition table, because it didn't have the correct BIOS geometry. It is safe to ignore,but ignoring may cause (fixable) problems with some boot loaders. Lovely wish I knew that prior to mucking around with the partitions. The data is there. I just need to get to it. At last resort I did this: dd if=/dev/hda5 of=/path/to/network/drive With my network this will take a while. Even then this is reaching for straws. Does anyone have any other ideas? Quote Link to comment Share on other sites More sharing options...
ac_dispatcher Posted November 9, 2004 Author Report Share Posted November 9, 2004 (edited) OK the dd didnt work. Over file size limit. What about formatting hda5 so it all looks nice then try a data recovery? Edited November 9, 2004 by ac_dispatcher Quote Link to comment Share on other sites More sharing options...
