Maxim,
Is it possible to get recover the Palmar,Spyglass without help of "Unlocked PCB" ? I mean only PC3000 is not sufficient for those family (hdd) ?

betty, For now the unlocked PCB is necessary to work with Palmer drives.

Yes, definitely. I dealt palmar more easily due to new version.

Yes, you need to buy UNLOCKED PCB

Correct (but you can get SA access using Spyglass on older version PC3K; still need unlocked PCB).

Hello all!

Anybody know what is different about these 'unlocked' PCBs? I see a few people out there selling these drives as 'unlocked' but for a ridicules amount. I would be very curious what the difference is in the firmware that makes these drives such a - in the butt to work on.

If anyone knows, please do share. :-)

Thanks.

Fraser

For one, the PCB is SED locked inside itself. You literally can't even read the ROM short of removing it and reading by an external programmer. So the unlocked ones are PCBs that don't have the built in SED lock. Most likely these are getting sourced from a country where this type of encryption is regulated by local laws so it's factory disabled.

Then there's the issue of the translator. Apparently, with these, the translator is built/updated as data is added to the drive. The problem is, certain firmware operations and even swapping heads that aren't fully compatible can cause the translaor to reset and all data will be returned as 00 00 because it thinks there's no data there and doesn't even try to access the sectors.
