That means the drive was detected as being Single-Ended, Ultra-Wide, 
Not LVD Ultra2 Wide (that would be 80.0MB/s). Are you using the 
correct type of SCSI bus terminator for LVD? Is the drive jumpered to 
use LVD instead of SE?

Note also that under ideal conditions, the very best you'll get is 
30MB/s out of this drive:

If you want to fill the LVD SCSI channel, you need more than one 
drive on the bus, RAIDed in some way.

Secondly, you might want to try the esiop(4) driver instead of 
siop(4); it was split out from siop to take better advantage of the 
53c875 and higher.
