comment Rescue data from damaged hard disk
@Lexsys: Partial recovery of a sector is supported (instead of discarding the entire sector). From grc.com/srrecovery.htm: " ... with this "mostly correct" now-readable sector so that all but a few data bits of the file can still be read and used. This is obviously a huge improvement over losing the entire file due to one of its sectors being completely unreadable.

comment Rescue data from damaged hard disk
@Lexsys: I found a more accurate reference, grc.com/srrecovery.htm: "During the defective sector re-reading, the drive's read/write head is deliberately relocated to either side of the troubled sector -- and at varying distances -- so that when the head is again placed over the troublesome sector, it might come to rest at a slightly different position than it did last time ... and might allow the sector to be perfectly read."

@Lexsys: there is a very detailed description of how SpinRite works in this document: grc.com/files/technote.pdf, "SpinRite. What's Under The Hood."

comment Rescue data from damaged hard disk
@Lexsys: I don't know about gddrescue (I found packages.debian.org/sid/gddrescue) - do you have a reference to a good description? SpinRite tries to influence the physical movement of the read heads over the damanged sectors in order to get the right read signal that will allow correct reading of the sector. It is in-place recovery - data is written back to the disk in case the reading of the bad sector succeeds. It may try up several thousand times on the same sector.
