FWIW I have one of those drives. The mechanism was manufactured by JVC,
and I have not had much luck with it. I recall it being extremely
persnickety about errors on tapes, and even when I managed to get a whole
backup onto a tape without the drive going into fits, I was never able to
read that tape back to verify the data.
Yes. I have a box of unreadable backup tapes and data tapes that someone
else made while under the impression that the Gigatrend was really a
working tape drive. :-(
OTOH if the tapes had to be formatted before use and
were block
addressable, that might tend to explain why I had such terrible luck using
that drive as a normal tape device under unix. What was the prescribed
method for using a tape in this drive?
Scrabbling around in the back room, he finds the Gigatrend 1230 Operators
Manual. From Appendix B:
Press ONLINE to go offline
Press TEST to get to menu -- you want level 1.
Press SETUP to increment displayed digit
Press ONLINE to enter that level
In level 1 you want function 1
Cycle through digits with SETUP
Press ONLINE to select format function using default values.
Lights will blink "FFFF"
Insert tape and press ONLINE to activate format operation.
Simple, isn't it. I think I got it all correctly summarized from the manual.
If you want a copy of Appendix B TEST PROCEDURES it is only 8 pages.
Send me a postal address.
