I have this WD10JPVX-75JC3T0 that spins up, heads don't sound like they move.
Status register lights up BSY for only a half a second or so. PHY is on.
If I try to ID the drive or go into utility the BSY register comes back on but never goes ready in kernel mode.
I dumped the ROM and programmed it to a donor board with the same results.
Just wondering if someone can examine this ROM and determine if that is the issue.

I've managed to get the drive ready using a donor rom, and moving SA translator, SA Adaptives, and Heads map over to the donor ROM, but the drive only IDs with serial number and 0 capacity.
Reading module 02 gets VSC ERROR UNSUP ACTION CODE, but I am able to read SA modules by ID.

If you already have SA access try restore ROM from SA modules.
If not, Load LDR with donor ROM (check SA can read, for firebird I think 4F dependency is not present) and search SA for module. Restore ROM

Donor ROM with same version and same offsets in directory start should give access anyway.
