Hello all,
Long time listener, first time caller...
I hope someone can shed some light on a tape issue that has arisen between
two different locations within my company. On system A we've created some
tapes using a generic "tar cvf /dev/rmt0h <dir>" to a DLT7000 drive, but
these are turning out to be unreadable on system B, with a TZ88
drive. Some details are appended below (in which System B has a tape from
System A mounted).
My fundamental question would be, do we stand a chance of reading these
tapes on system B, or are these drives just plain incompatible? Sorry if
this is a dumb question, but I haven't really dealt much with tape drives
since 1600 bpi was considered high density...
