MK8007GAH 1.8" Toshiba Parameter storage

Hi,

Anyone has an idea where the parameters for this drive are stored ?
The Marvell chip is cooked, so i hope it is not in that one.
Any help appreciated.

Thanks in advance,

Hi Dobre,

Let's think a bit...
IC6 seems to be Motor Combo,
IC21 must be Buffer RAM,
IC26 seems to be a DC-DC converter,
As I don't see any other IC, I am afraid the ROM code is in the Marvel.....
However I am almost sure there's a copy on the surface, but I haven't have time to research this matter and how to load this code into a new PCB....
so I don't have a solution for this thing at the moment.
sorry,
pepe

That's correct pepe
ROM is inside Marvell chip

Hi Helpdisk,

As soon as i put power on it the pcb draws some amps and the Marvell Chip gets really really hot.
