HD Data Recovery
Hey list,
A few days ago one of my parents' computers stopped booting, and they
don't have any external backups, so I have to try and backup the data.
BIOS POST revealed that the cause was a hard disk error. I swapped the
drive in as a slave on another comp of mine and attempted to see if I
could salvage any data. However, the kernel doesn't recognize the
partitions and create /dev entries for them. Gparted wouldn't even
recognize the disk. At this point, I assumed it was a partition table
problem, as dmesg revealed that the kernel does see the disk:
# dmesg | grep sdb
[ 3.965910] sd 1:0:0:0: [sdb] 0 512-byte logical blocks: (0 B/0 B)
[ 3.965956] sd 1:0:0:0: [sdb] Write Protect is off
[ 3.965959] sd 1:0:0:0: [sdb] Mode Sense: 00 3a 00 00
[ 3.965980] sd 1:0:0:0: [sdb] Write cache: enabled, read cache:
enabled, doesn't support DPO or FUA
[ 3.966229] sd 1:0:0:0: [sdb] Attached SCSI disk
From here, it looks like the disk geometry is shot (0 blocks!?), but I
figured I'd see if I could rescue.
However, I don't get promising results from the standard disk tools:
# testdisk /dev/sdb
--snip--
Unable to open file or device /dev/sdb
--snip--
# gpart /dev/sdb
*** Fatal error: dev(/dev/sdb): seek failure.
Both programs give "no disk" errors with /dev/sdc, so I know it's
getting at the disk, but just completely failing to do anything.
If anyone knows how I can recover the data off the hard disk, it would
be much appreciated.
Thanks,
