NOOB, I don't know where to begin describing my problem / attempts at recovery.

Hello, I guess I should start saying I am as scientist, biologist, and Linux dabbler (since about 2015). Some TI-BASIC (TI-82), mid 90s, in high school, and some 6502 assembly, early 2000s after college, but couldn't afford to pursue my interest in MASM AND TASM and "real computing", at the

Hexadecimal input

Dear Ddrescue, I wanted to use following command on a 2TB disk, because it was taking to much time for pass 5, so tried to use the part of the disk with --cpass=1 first, using hexadecimal numbers to define the bytes to be read. The error message from ddrescue is also given. What am I doing

Re: Suggestion about error control

To be honest I don???t think I ever used any T10 documentation for the SCSI passthrough. It is needed for ATA passthrough, but there is plenty of other documentation and open source code for the SCSI passthrough, and I know for sure everything I found was free. And from what I can tell, the

Re: Suggestion about error control

The tools mentioned (hddsuperclone and DMDE) are not open source and have paid versions for a reason. The authors have spent much time and effort working on them to make them special. Realizing the different error conditions of a device cannot be done with normal commands. Comparing those
