I'm always having a hard time to figure out what `byte 9' might be.
If i'm counting correctly, byte 9 is the MSB byte of the block length
parameter in the block descriptor.  It is really weird that the drive
complains about it being 0.

Can you run the following on your drive?

scsi -f /dev/rsd2.ctl -v -c "1a 0 0 0 v:i1 0" 12 -i 12 \
"{mode data len} i1 {type} i1 {device-specific} i1 {blkdesc len} i1 \
{density} i1 {numblk} i3 {reserved} i1 {bllen} i3"
mode data len:  15 
type:  0 
device-specific:  16 
blkdesc len:  8 
density:  0 
numblk:  0 
reserved:  0 
bllen:  512 

Btw., what drive (vendor) is it?
