Looking for Toshiba MK3275GSX resources

[yco]

Hi gurus.

I came across a rare Toshiba drive (or maybe it's rare in my area).
Heads are OK, so is PCB. Looks like ROM problem.

Does anyone have resources for this model?

Thanks,

ROM problem? Doubtful. Not impossible but unlikely.

What are the symptoms?

Hi pcimage. Sorry for very later reply, but we are quite busy here.

For starters - drive was clicking badly. I couldn't get exact donor so I used 76GSX for head swap.
Drive is still clicking exactly the same way. I tried patient heads in the donor drive and it works perfect.
I managed to save most of the CPs and dumped ROM via terminal from patient drive.
I got resources for similar drive and tried to compare them with my drive, and found many differences.
I don't remember now which exactly CPs I wrote into patient PCB, but at the moment drive is not clicking.
It stays BSY for a long time, then comes up DRD DSC with full SA access (using 76GSX utility), but no sector access at all.
I managed to save DD module (p-list) which is stored in service track, so there is an access to the media.
Also physical test runs OK. I cannot get access to G-List at all, cannot clear it (don't remember exactly what error it gives right now - I don't have the drive hooked up to PC3K).
It looks weird thou. Possibly there is a physical defect on SA preventing access to the g-list track.

Any ideas?

If DRD and DSC shows up with full SA access (and assuming you have the updated Data Extractor) you can try using the Toshiba G-List error solution utility within the DE. Then, try to read sectors in PIO mode.
