Can't open old tape!
Posted on 1998-10-06
I have an 8mm tape that was dumped back in '96. The system it was dumped on is an Auspex server running Sun OS 4.1.3 at the time(and I'm quite sure it was dumped with the b 126 option). The server now runs 4.1.4 and some incantation of an auspex bug package.
For some reason, I'm unable to restore from this tape using restore on that server, ufsrestore on a Solaris 2.3 machine I have or using dd to manually read. I can query the tape using mt, and I can extract the Table of COntents using tar.
But when I try to initiate an interactive restore it ends up spitting out:
Media Block Size is 20
tape not in dump format.
I know that this tape is(or was) in dump format as we had restored from it before.
Anyone know how I can determine what is wrong here and/or how I may force the output to a different readable block size?
Thanks for any help!
