[comp.sys.mac.hardware] Formatting problems with a Syquest

My father bought a Syquest drive 6 months ago (exact brand unknown)
and it seems to have trouble formatting cartridges.

He has been using 4 Syquest brand cartridges for the last 6 months
with no apparent problem.  Then, he bought 2 new cartridges (Mass
Microsystems brand), could not format them, so he had them formatted
at a local store.  They worked fine for one backup, then started
having problems: backup gets stuck after some time.  Tried with one
of the older cartridges: no problem (so the drive is OK).  Tried
again with the new cartridge: fail.  From then on, all cartridges
failed in the middle of the backup.

The store which sold the drive went under 2 months ago.

The system setup is: a Mac SE/30 w/ 2 Meg and 40 Meg HD, running
system 6.0.3 (I think).

There is a formatting program coming with the drive, called Smart
Format.  When trying to "test" the cartridge, it stops after some time
with the following message:
  SCSI error occured
  Sense Key: $04 Hardware Error
  Add'l sense code: $02 No seek complete
  Logical block #: $000022EE

When trying to format the cartridge, it stops with the following
message
  Could not format Device because SCSI error occured
  Sense Key: $03 Medium Error
  Add'l sense code: $32 No defect spare Location available
  Logical #: $00002525

Because of the previous message, I suspect that the formatting program
can't deal very well with defective blocks (just a guess).  Could that
be the case?  Would using a different formatting program (I have seen
Silverlining mentioned here before) make a difference?

Please reply by email.

Thanks.
