Summary 8mm tape problem

Date: Sat May 06 1995 - 02:23:53 CDT

I received a few responces to my problem but nothing has worked so
far - Yes I regularily clean the drive. One sugestion that looked
promising was to use /dev/rmt/0l (for low density) but that
failed also.

Another suggestion which I did not try was to contact Exabyte for
a firmware revision that will correct the problem. This apparently
fixed a similiar problem for another user.

Lastly, I did as all good UNIX administrators are taught to do, PUNT.
I moved the drive to another Solaris system and it is happy in its new
home. Works fine!

Thanks to all.

I have installed solaris 2.4 with ONLY the patches provided on the distribution
CD_ROM. Is there another patch kicking around that may solve the problem?
