Re: how to retrieve info from a bad disk?



The final, and arguably most important thing is to always back up your
important data...

I know it's a little late in the game, but this is an important lesson
to learn for future reference...

/dev/sdb1  with correct sie, but no possibility to
retive files.
I tried   ntfs-3g    /dev/sdb1  t         gave   segmentaion fault
I tried  testdisk        it   analysed the disk and gathered the data,   I
tried to list the files ,    it gave same error as ntfs-3g, I mean
 segmentation fault??


Is there  another rescue software ??
thanks for help

regards

Firstly, copy the entire disk to another one of the same or larger size by
booting from a live distro such as sysrecuecd and using dd (e.g. dd
if=/dev/sda of=/dev/sdb).

Secondly, using the copy of the disk, try to rescue the disk using testdisk.
This may reconstruct the partition table. If it doesn't work, you can try
photorec to recover files. For photorec, recover the files to a third disk,
not to the original or copy.
