DLT III reinitialization in TZ85?

» close window

The Question is:

I am trying to re-use some DLT III cartridges which were originally
initialized and used in a TZ87 drive.
I am trying to re-init them in a TF85 drive.  Most of the cartridges are
coming up with "parity error" on init. Trying to MOUNT results in "not
I've re initialized (/media=compact,/media=nocompact) them in the TZ87
successfully and can write to them (backup/copy) but when moving to the
TF85, I still get "parity errors" on attempting to init them.
I've tried to use a "bulk eraser" (eg, strong magnetic field) to erase them,
no help.
The TZ87 is in a BA350 shelf, connected to an Alpha8400 running OpenVMS 6.2.
The TF85 is connected to a Vax4500, OpenVMS 6.2.
Is there some way to re-use/re-init these tapes so that they can be used in
the TF85?

The Answer is :

  The DLT drives can reinitialize any DLT cassette up to the maximum
  density supported by the drive -- the TZ85 and TZ86 cannot reinitialize
  higher-density tapes.
  The Wizard would also suggest trying a stronger bulk degausser.
