Your status output looks OK. Notice that your tape is write-protected.
It is possible that your drive or tape is bad. I would get a new tape
if possible, make sure the write protect is off and the use tar or dd
to write a file and try and read it back. Not sure what else you can do.

my tape is OK, but with this Linux driver I just cannot read the
write protected tape. For me its not the problem any more, but
this must be an error in the driver.
Thank You

Try add "bs=512" to your dd command. The tape has a block
size of 512 according to your status command and you typically
need to read a tape with the correct block size.
QIC tape drives also have other oddities when you write to them.
