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.
Help?
Well, looks like cleaning did help after all :-) the error above
looks like a simple block-size mismatch. You need to set the
proper block size with MOUNT, like
$ MOUNT/FOREIGN/BLOCK=10240/RECORD=10240 MUA0
if the tape has been written with 10 kB blocks. When you
do not set the block/record size it assumes default 512
I believe, which means it can't get a full tape block into
its memory buffer, which is another word for data overrun.
You're on the path to success :-)
