Good to know! I've regularly used dd on drives, but not on ones that
were in trouble (maybe once ...)

But now drives are at the point that you cannot guarantee an error-free
scan even on just one pass, I guess I'll have to make sure I use
ddrescue from now on - I usually just read an (old) drive into a file on
a new larger hard disk, loopmount it, and proceed from there ... never
had any trouble so far ...

Cheers,
