Hmmm, another piece of the puzzle perhaps. If memory serves, "read
sector buffer" and "identify" are two operations that are restricted to
PIO 0 mode (I'll have to check, but I think that's true).
If you issue a "read sector buffer" right after the LBA read sector
aborts, do you get the correct data back?
If so, I wonder if the drive is expecting that DMA mode will be used by
Just a thought.
