Though i admit that it's not supposed to be a good response to fall
into panic, the ft device is not yet ready to be read from and written
to. All the data transfer has to be done via ioctl's. This is mainly
due to the braindead architecture of those drives. I don't remember
exactly the command, but there must be something like qtar of ftar to
backup/restore on floppy tapes.
