While the sticker might say 94171-307, a SCSI query for it's ID might
reveal it is a 94171-9, that is  a MacWren IV. The geometry of both drives
is probably 1409 cylinders, 9 heads, 46 sectors.  I beleive it has a
slightly smaller capacity than the 94171-344.  I succesfully formatted one
on a sun 4-110, but when came time to boot of of it,  I got the following
error: sense key =2 error =5;

The only difference between a Wren and MacWren is the firmware.

I anyone ever got a sun 4-110 to boot off a 94171-307 (94171-9) I would
appreciate hearing about it.
