[SOLVED] Fujitech Clone dock 2 and cloning hdd with lots of bad sectors

[Kiippa]

I’m looking ways to save files from hdd with lots of bad sectors (approximately 1,5%) and one option that popped into my mind is to use hdd duplicator to copy contents of “badder” hdd to new good and fresh one.

So, if source hdd has bad sector, will that same sector in destination (identical) hdd marked as bad or that sector skipped, written zeros or how them are handled in destination hdd?

Background: hdd went dead and gotten back to live by changind pcb and transferring old bios to new pcb. But only half way there as even pc bios sees the hdd, it is seen as unpartiotioned and unformatted by windows now. And looking for ways to salvage pictures and videos and one thought is to work on (physically) better hdd and thus having an idea to duplicate contents.

Bad sectors will probably just be skipped, losing whatever data may have resided there.
Or, the clone process will simply stop at that point.

You need an intelligent, multi-pass cloning tool. HDDSuperClone and ddrescue understand how to deal with bad sectors or bad heads.

HDDSuperClone is optimised to skip over bad heads and clone them at the very end. Ordinary cloning tools will keep thrashing a bad sector, thereby accelerating the failure of the drive. A tool such as ddrutility can parse the log files produced by HDDSuperClone and ddrescue, and identify those files that are affected by bad sectors.
