This won't be of immediate help, but just fyi: I'm using an old hp
surestore 6000 (DDS-2) tape drive to back up my i2000 (aka big sur).
Each backup is usually ~8GB in size and I haven't seen any problems so
far (I also use dump/restore).

Can't help with deciphering the error message.  I vaguely recall that
there may have been a problem with early versions of "dump".  The one
I'm using is 0.4b27/libext2fs v1.27 as shipped by Debian/ia64.
