I get this same issue (x86, fairly recent -current, and it's been happening
for at least 3-6 months, though it may have been longer than that), and the
following workaround did it for me (assuming your drive is SCSI).

It appears that for some reason the MODE_SELECT is failing with the error
you show above (for more detail, see my previous mails on this subject,
URLs to which are at the end of the mail).

I sent a fairly thorough trace of this with SCSIDEBUG output a while ago
to the lists... My initial post and a follow up with a bit more analysis
