Tape Drive has some problem, so that we need to erase the data on /dev/nst0 but actually we are backing up the data on /dev/st0.
Does anybody know the different between /dev/st0 and /dev/nst0 ???
I read on an ebook, and found that /dev/nst0 uses nonrewinding device file. Is that true ?

you must specify the device using its device file. These files are stored in
/dev and are understood by the kernel to
stimulate the use of device drivers that control the device. Archiving programs
that use the device files need no knowledge of how to make the device work. Here
are some typical device files you may find on Linux systems:
