Hi.  I pulled the following off of GEnie the other day.  I'll let it
speak for itself:

WARNING:

Owners of Teac 150 MB Backup units should be aware of a ROM Bug which allows
these drives to incorrectly overwrite data by mispositioning the tape during
backups.

This problem was identified in February 1991 by Dantz Development, publishers
of Retrospect.

Teac Japan has acknowledged this bug within the past week.

This condition is results in a Retrospect error message 106 (data overwrite
attempt) - and is a "fatal error" - complete data loss.

Teac believes that the 150MB ROM Rev. E will correct this problem. Accoring to
Retrospect Technical Support, the PD Utility SCSI Probe, (file #17308 in the
GEnie Mac Library) will report what Teac ROM is in any given tape drive unit.

Your drive vendor can contact Larry Zulch at Dantz for a copy of the Teac
acknowledgement letter. Teac is supposedly committed to upgrading installed
devices to ROM Rev. E.

In the interim, always veryify files before deleting them from your ha  hard
disk to insure that they have been correctly recorded to tape!
