Data recovery and disk repair questions and discussions related to old-fashioned SATA, SAS, SCSI, IDE, MFM hard drives - any type of storage device that has moving parts

Toshiba hybrid drive mq01abd100h. Drive spins up, sounds fine, SMART diagnostics report health OK, no bad or pending sectors. And yet data is completely unreadable. From searching around it appears to be a relatively common issue on these models, possibly a NAND failure? Anyone have success with these? Is a PCB swap with ROM transfer possible on these hybrid drives?

The following thread suggests that, at least in some SSHDs, one could perform a secure erase on a donor drive, thereby clearing the donor's NAND cache, and then transfer the patient ROM to the donor PCB.
https://www.data-medics.com/forum/st100 ... t1732.htmlAre you able to read the ROM?
Would it be worthwhile to check the PCB voltages? I could help you with that if you could provide a detailed photo.

Turns out there was a Carbonite backup so it was not necessary to recover data from the drive but I will file this idea away for a future case. The link seems to suggest P3K is required to perform the secure erase, any idea if there's another way?
Thanks as always!

NAND is faulty. There's a solution.
