Writes won't work at all, since all our `streamer' drives do not support writing in the middle of a tape, they only allow appending. This is different with 9-track reel-to-reel tapes which are random access media. Read/only mounting should work on the (almost forgotten, but basically supported) block device, but all i get when trying it are IO errors. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
