help recovering HD
I don't have the partition table listing (I'm not at home now) but it seems that it may be corrupt. I'm looking for advice on how I can recover the data off this drive and to see if the drive is bad.
Please let me know what info I can provide to help.
I going to try to dd the data to a new HD, but how do I do that if the HD's are different sizes? And, the source drive has server al partitions... do I mount those separately on the new HD once the old one is copied?
Thanks!
Bob

Re: help recovering HD
If you have another system with Linux on it, then simply connect the faulty hard drive to it and try to mount it after the system has booted. If your lucky, you might be able to get access to your data and then copy them straight to the system your using.
If you haven't got another system, then look for a small hdd to temporarely install linux on it and try the above.
I hope this helps !
Cheers,
Chris P.

Re: help recovering HD
Separately, it seems that the partition table is messed up:
device boot start end blocks ID
/dev/hda1 * 1 7 528884+ 83
/dev/hda2 8 2912 21961800 83
/dev/hda3 2913 5182 17161200 83
/dev/hda4 5183 5295 854280 f
/dev/hda5 5183 5234 393088+ 83
/dev/hda6 5235 5269 264568+ 83
/dev/hda7 5270 5295 196528+ 82
Notice how partitions 4, 5, and 6 seem to overlap! Also note that partition 4 is set as a WIN95 Ext'd (LBA) partition. I never set it that way.
Also, it seems that copies of the superblock aren't working to restore that.
If I'd have to guess, I'd say that some process (perhaps Samba?) corrupted the FS. Any other help on getting data from this drive, please??
I have another HD that I could install and move data, but I don't know how I can if I can't mount the partitions.
Thanks,
Bob

/dev/hda1 * 1 7 52888+ 83
I'm thinking maybe I can guess at what the correct partition info should be from the block count?
Thanks,
Bob

Re: help recovering HD
e2fsck -nv /dev/hda2 > file 2>&1
I get this output:
e2fsck 1.27 (8-Mar-2002)
Pass 1: Checking inodes, blocks, and sizes
Error reading block 65541 (Attempt to read block from filesystem resulted in short read) while doing inode scan. Ignore error? no
Error while scanning inodes (32704): Can't read next inode
(This is only stdout. I can't seem to get stderr to show up in the file?)
Any other ideas how to get the data off? Or fix the drive?
Bob

Re: help recovering HD
I you would also try from /dev/hda6 up and do a backup of good partition you find.
In the end You may have to accept that you have lost a parttion !
I also noticed that you say no to correct error on fsck
I have reread man e2fsck and did you try e2fsck -p from hda6 upwards (BEWARE -p will try and correct) as oppose to -n that does inform (report bad blocks) you but does not do correction on your file system.
Keep us informed
Hope this helps
