This Toshiba PCB 003138A only die "power off" nothing else I have experience in at least 1000 drives I have worked.
Something confusing clear this first..
1- drive is dead and stuck in bsy and motor doesn't spin (i assume that the problem in the pcb) so i desoldring the rom and make a dump of it and wrote the dump in another pcb and test it but nothing is changed drive stuck in bsy and motor doesn't spin.
Why you didn't swap the original rom to donor pcb and try may be you missing something?

I already try this after my 1st attamp but i didn't mention to sorry i prefer to making dump of the original rom and wrote it to donor rom but after my 1st attamp dosnt work i soldering the patient rom on the donor pcb and same results stuck in bsy and motor dosent spin.Quote:
2- i desoldering the dononr rom and soldering it on patient pcb drive spin up with clicking and still stuck on bsy no matter how long !? the drive shows id after while only if i isolate hda from pcb.
Yes this is what exactly should be no correct head map found from donor rom.

Soldering donor rom after wrote dump file to it thats what i meanQuote:
What?? i desoldering the dononr rom and soldering it on patient pcb drive spin up with clicking, patient pcb drive spin up???

After making 3 dumps file by using 3 deferent programmer i noticed that there is a defrence in some bit in hex decimal all dump isn't the same so i try all of them and all of them give same result on donor pcb but when i try on patient pcb one of them give different result drive spin up with none stop clicking !? So i test patient pcb on donor hard disk and same result none stop clicking after that i soldering the donor rom to the patient pcb after wrote donor dump on it and test it on donor hard disk and same result none stop clicking !? So i maked sure of the the patient pcb doesn't work as it shoul be
The problem in the patient rom and pcb
After wrote dump file on donor rom give different result on the patient pcb !? And i maked sure of that patient pcb is faulty.
One more thing i test donor pcb with its native rom on patient hard disk and its start spin up normaly no clicking
