Error 5 in principle means beginning of medium but FITLD normally
would process that indicator correctly.  I suspect something wrong
with the tape - what do PRTTP and TPHEAD say?  You coudl run dd to
copy the tape file to disk and then use FITLD on the disk file.
Make sure that dd uses an appropriate blocksize (n * 2880 bytes with n
= 1 - 10).
