Hello All

My friend has been having trouble with their tape
drive - ditto 2 gb internal. I was suspecting that
his machine may have some hardware conflict issues
so I took the tape drive home, installed ftape-util
from debian woody and tried to use the drive.

I retensioned the tape and then tried to get a list
of the files on the tape cassette:
 
 $tar -tzvf /dev/nqft0

I did get some output but after 3 hours it had still
not finished. I finally killed the tar process inorder
to stop it.

Almost all the time that it was running it was outputing
the error messages like the following:

Jul 28 15:32:15 Cuckoo-2 kernel: [059]     ftape-read.c (correct_and_copy_fraction) - ecc corrected segment: 3877.

Any clues as to what this error message means? Is the
drive destined for the rubbish bin or is there something
I or my friend can do to get it working properly? Trouble-
shooting tips would also be very welcome.

I include much of my /var/log/messages below if anyone is
interested.

Thanx in advance!!!
