292.Sh BUGS
293This driver lacks many of the hacks required to deal with older devices.
294Many older
295.Tn SCSI-1
296devices may not work properly with this driver yet.
297.Pp
298Additionally, certain
299tapes (QIC tapes mostly) that were written under
300.Fx
3012.X
302are not automatically read correctly with this driver: you may need to
303explicitly set variable block mode or set to the blocksize that works best
304for your device in order to read tapes written under
305.Fx
3062.X.

307.Pp
308Fine grained density and compression mode support that is bound to specific
309device names needs to be added.
310.Pp
311Support for fast indexing by use of partitions is missing.
308Partitions are only supported for status information and location.
309It would be nice to add support for creating and editing tape partitions.
