I had the same problem, same drive, tried same solutions, same
outcome. Basically ricoh mp6200s drives are pants. I suspect
they don't work well with scsi adaptors other than adaptec.
I have now gone for eide with a yamaha 4416e which so far is
very reliable, though not 100%. Plextor are generally considered
THE BEST, but at a premium.
