Thanks for the error identification. The other drive is of a
*different* model. This drive showed this behavior from the day I
bought it. The drive could be going bad, but I doubt it. Is it
possible that this manufacturer (Conner) has some peculiar
implementation of the spec? I recall reading on this list sometime
back of similar workarounds to unusual drives.

Can I turn on debug mode in runtime, or do I need to recompile
ide-scsi?

Take care,
