Does anyone know how to identify and mark bad blocks on these generic SCSI drives?  I have a 160Mb Wren and a 780Mb Hitatchi, both of which contain 0  size for 
Badblk.sys file.  They are both installed on our VAXStation 3100 running VMS
5.2.

Ive tried >>>TEST 75 from the opcom prompt which ran for several hours but did
not create any bad block data.  I've also tried $ANALYZE/MEDIA which reported
123 bad blocks on the 780Mb drive, but would not output the data to a file.

Checking with DEC, they basically said that analyze/media only works with their
drives, and to ask the vendor.  The vendor doesn't seem to understand why 
there is a problem, and keeps sending me more and more drives to try (I have 6
now!)  

Thanx for any help.  PS: The drives continuously error to syserr.log saying
BAD SENSE DATA.
