PATCH: Fixes for ide-disk.c
Quoted 5 lines · John Bradford
Did we ever establish what the best way to ensure that the write cache is flushed, is? An explicit cache flush and spin down are both necessary, but I had problems with drives spinning back up when we did the spindown first.
Disks that don't support flush should be sent an IDLE command, IIRC.

If the drive is compliant it will issue an abort if not supported. Otherwise one should check the identify page; however, there are several cases where the bits are improperly set. Another double edge sword to make the driver more interesting.
Cheers,
