Swap circuit board on HD?
A friend's hard drive quit working, and he's anxious to get the data off it -- without paying DriveSavers' astronomical fees if possible. The disk spins up, clicks once or twice, then spins down. I have another disk of the same model (IBM Travelstar DJSA-220 20GB, it's an ATA drive) that works okay, but SMART Utility says it's failing, so it's been retired. I've read it's sometimes possible to swap the PCB from one drive to another to get a dead drive going, and thought I'd try that. Can anyone speak from experience?
And does anyone know what size Torx screws these are that hold the PCB to the drive? They're smaller than my IFixIt® T-6 driver; they appear to be the same size as on a late-model Hitachi Travelstar SATA drive (IBM sold its drive business to Hitachi back around the time of the transition from ATA to SATA).
