From Debrick guide V1, you tried the following?

“If DiskInternals Linux Reader will not recognize the partitions, it may be because you have a corrupt partition table.
Try using R-Linux http://www.r-tt.com/free_linux_recovery/Download.shtml

if you cannot see the drive with gparted or other app which allows to see Linux partitions on Win, the drive is probably dead.

  

Also, are you sure USB-SATA adapter is good?

And last, you could try some Linux forums for help, these devices have Debian Lenny version.
