Hi! Wondering if anyone out there knows a way to change the CHS values of a CF Card?

Thanks,

Which card? What kind of motherboard? Which year/era?

Ah!! You are right! Sorry I did not provide more details! I have numerous different CF cards that I am trying to get working. Motherboard is an old Intel Celeron and OS is an old Linux variant. The card needs to wind up having very specific values for things to work. I need it to be 1000C 16H 32S. Problem I am running into is most cards are 63S so I am trying to find a way to change the card to 32S.
Not really sure if that is possible or not but I figured this would be the place to ask since I have seen similar discussions here. Though not specifically about changing those values.

Thank you,

I don't know about hacking the firmware, but old CHS IDE drives could be reconfigured with a custom CHS translation by the BIOS during the POST. This change was volatile, ie it would not survive a power cycle.

There is an ATA command that is responsible for reconfiguring these CHS parameters, but I would need to search through the old ATA standards documents to find it.

Yes I definitely need something that is persistent. I would appreciate any assistance or guidance you could give.

I have never hacked a CF card. I expect that you would need to physically dump the firmware, make some edits, and write it back. How you go about this would be totally dependent on the particular card.

There was a SanDisk tool in an older thread that could convert between ATA and ATAPI configurations. Perhaps it could be adapted to do what you want. IIRC, the OP in that thread lost interest in the job.
