Toshiba - MQ03UBB200 Whats The Issue [ Rom/Heads/Platter ]

[Amarbir[CDR-Labs]]

Hi All,
Received This Case From a Routine Dealer .The patient tried to calibrate on sa ,Feels good but then starts knocking .I replaced the Heads To This From 2 Good Donors But Situation is Same .I could not see any contamination of the heads so i am ruling out surface degradation .I then took a good known pcb of same drive and tried that no knocking then is rom a issue in my case .The Rom is attached

PS : Frank i tried the rom cp extraction tools you made but both the tools could not find anything and said unknown rom .

It's not Head problem I think cause when you connect donor PCB with donor rom drive try to calibrate normal when you connect original Rom it start clicking ....

Well,
This would mean donor head adaptives are different from patient head adaptives .Do we have any method to shift adaptives like wdc and seagate ? .On The Other Hand i do not have a data board for this which i should have to experiment a little .I am not a fanboy on usb to data converstion
