<EM>This HOWTO discusses essential do's and dont's for the <CODE>ftape</CODE>
|
|
floppy tape driver under Linux. It focusses on the newest version
|
|
which is <CODE>ftape-4.02</CODE> at the time of this writing. This HOWTO is to
|
|
be intended as first step help and source of information.
|
|
The <CODE>ftape</CODE> driver interfaces to QIC-40, QIC-80, QIC-3010 and
|
|
QIC-3020 compatible drives, and to the Iomega Ditto 2GB and Ditto Max
|
|
drives. The QIC-3010 and QIC-3020 standards are also known as
|
|
`Travan' (TR-2 and TR-3). These drives connect via the floppy disk
|
|
controller (<B>FDC</B>) which may be either an internal FDC or inside of
|
|
certain parallel port floppy tape drives. Please refer to the section
|
|
<A HREF="Ftape-HOWTO-6.html#supp_drives">Supported drives</A> for further
|
|
information.
|
|
<CODE>ftape</CODE> <B>does not</B> cover SCSI or QIC-02 tape drives. DAT tape
|
|
drives usually (always?) connect to a SCSI controller.
|
|
This is but one of the Linux HOWTO documents. You can get an index of
|
|
the HOWTOs from
|
|
<A HREF="http://sunsite.unc.edu/LDP/HOWTO/HOWTO-INDEX.html">the Linux HOWTO index</A>, while the real HOWTO's can be fetched (using
|
|
<CODE>ftp</CODE>) from <CODE>sunsite.unc.edu:pub/Linux/doc/HOWTO</CODE> (this is
|
|
the ``official'' place) or via the World Wide Web from
|
