I think that you are on to a bit of a loser with this card for anything but a CDROM under FreeBSD. A year or so ago, I got one of these cards free and started to hook up a SCSI disk I had lying around. I could format, disklabel etc, but could not copy reliably. I had a look at the source to the driver and it doesn't really seem to be written with anything other than a CDROM in mind. The block size seems to be fixed at 2kB, DMA is a faked etc, (all from memory). I think (but cant remember) that the errors were the same as you are seeing. However, under Win95 the drive and card were fine.
