In 40+ years, I've had remarkably good luck with hard drives. Prob had over 1000 go thorugh my hands, and only had a couple real failures.
Are you sure they've actually failed (make unusual noises etc.) or could it just be that the boot sectors/OSs have been damaged and
the drives need to reformatted/restores.
I've only "fixed" one of the actual defective drives... This was a case of "stiction" where one of the drive heads stuck to the platter
and it wouldn't spin up. I disassembled it, freed the head, polished the spot on the platter ... didn't expect much, but the drive
did come back, formatted without errors and I used it for several more years (never really trusted it so I didn't put valuable stuff
on it).
Not sure I'd try this on a laptop drive ... very small room to work!
