I think photorec is the right tool for you. It's part of the testdisk
package, which somebody mentioned already. I've used photorec several
times to recover files (all kinds, not just photos) from drives that
were unreadable by other means.

I have already started testdisk and it is analysing the disk since the
last hour or so. Should be finished soon. It might give me an hint as to
what is the status of the disk.

Thanks,
KS.

Good luck!

Install smartmontools and try to run smartctl -a /dev/sdb on it. Then
post the output. It might be that smartctl doesn't work over USB. In
that case you would have to connect the disk directly via SATA/IDE.

No, it coudn't find any partition table after 2 passes.

I started photorec and it has found hundred's of files. It says it will
take around 20 more hours to finish.

The HDD is connected to internal SATA connector. Sadly, the external USB
drives sold these days don't have the capability of reading SMART data.
I have an old WD external disk which does, but a newer Lacie does not
and it doesn't spin down the HDD either!

Waiting for photorec to finish.

Hi,

I made a list of forensics packages:

Although you missed most popular

testdisk

this list was a good one.
