This is the question... what is the "correct data"? Would I be able
to see the cyl/sector/head information I've set before in that
buffer? I didn't understand what the sector buffer really is by
reading the docs.
Well, ideally, this contains the data of the last sector
transferred. It provides a sanity check on the data transfer path.
So you should be able to do a "read sector buffer" after the
aborted "read sector" and get some clue.
I now tried something different. I issued a "format track command" and
sent 512 bytes afterwards as described in the ata spec. The drive does
not respond with an error, and when I read the sector buffer right
afterwards, it contains the exact data I transfered after I issued the
format track command.
