After cleaning, same problem. Now, when I try to copy
data off the tape
using "COPY MUA0 NEWS.TAR", VMS gives me these errors:
%COPY-E-READERR, error reading _MUA0:[].;
-RMS-F-RER, file read error
-SYSTEM-W-DATAOVER, data overrun
%COPY-W-NOTCMPLT, _MUA0:[].; not completely copied
when I use dump, like "DUMP MUA0 /OUT=NEWS.DMP", it works just perfectly
fine, which leads me to believe it might be a VMS problem. Prior to now,
I was able to copy straight from the foreign mounted volume OK, but now
it's not working at all, even after I power-cycled the drive and the vax.
When you DUMP the tape, DUMP uses a large buffer. When you use COPY, you
get the default RMS buffer size, which is too small for the tape blocks.
Use
DUMP MUA0:/BLOCK=COUNT=1
to get the block size, then
MOUNT/FOREIGN/BLOCK=xxx MUA0:
to mount the tape with the right blocksize. COPY should then work.
