[comp.sys.mac] Restoring Mirror harddisk with tape drive for Mac+

lmeanab@astrid.ericsson.se (Anders Abrahamsson TX/UZ) (12/20/88)

Promised to mail this for a Mac-user that do not have
access to UUCP/News:

"Equipment:
 Macintosh Plus, 40MB HD Mirror 40/40 with build-in 40MB
 back-up tape drive. According to manufacturer, now defunct,
 the unit consists of a NEC HD and a 3M tape back-up.
 Back-up and restoration software Mirror version 2.1.
 Harddisk was not partitioned into volumes. Documents on disc
 were mainly Microsoft Word 3.01b.

 Problem:
 After harddisk crash and reformatting, version 2.1 will only
 restore the uppermost folders on the tape onto disk.
 When lower-hierarchy documents are specified for restoration,
 tape drive gives status report after several minutes stating
 that files could not be copied. If attempts of restoring files
 continue longer than one hour, resoration status report
 will state "File header error occured".

 Version 2.2 does not recognize the tape drive, stating that
 no cassette has been inserted.
 
 Version 2.3 will look for volumes and cannot find any. When
 restoration is attempted anyway, the tape drive will stop after
 18 secs. Status report indicates that restoration has been
 completed, but nothing has been copied to disk.
 
 Has anybody else had similar problems and is aware of a
 solution?"
