Code 0x01 in Tatu Ylonen SCSI driver

I've ported Tatu Ylonen's SCSI driver to my Unix system. And
it has been working flawlessly for some time.
However, I recently connected a Fujitsu M2249/SA drive and
I've come across a message from the drive that Mr. Ylonen's
driver doesn't handle.
I regularly get the message:
scsi: unknown message received from drive 2: 0x1
and the drive operates very poorly. Through some research of
my own, I've found that this is a MSG_EXTENDED code that is
not recognized. The following code excerpt is the generator
of the error message:
default:
if (a & 0x80)
break; /* assume it is an identify message */
printf("scsi: unknown message received from drive %d: %x\n",
unit,a);
break;
}
So, can anyone help me develop the code to handle this case? Any
help would be appreciated. Such as a fix for the code, information
on the 0x1 code, or references for general information on the
SCSI protocol.
Thanks in advanced.
