If no one is then at least it will sit in the archives or something. :-> I have a 2.1.5-RELEASE system and the patch (below) allows me to use 425ft tapes in my Colorado Jumbo 350 floppy tape drive. So far I haven't had any problems with this change and I have no idea whether or not this will break things for users of other types of drive. All the geometry numbers were taken from the QIC-80 standard which I downloaded from the QIC web site. Both the ft and lft programs work well with this change also. Is there any chance that this could be considered for -current? (or something..) Thanks, Joel... PS: If anyone is interested it takes about 1 hour to back up 150MB (my /home) and several hours to format a tape. If you hear about 1 MB/sec for this drive then they're talking about the dedicated controller board. Regular cleaning of the heads also helps. *** /sys/i386/isa/ft.c-orig Wed Dec 11 18:46:49 1996 --- sys/i386/isa/ft.c Thu Dec 12 14:40:08 1996 *************** *** 152,158 **** { 1, 3, "QIC-40", "295/900", 0, 0, 0, 0, 0 }, /* ??? */ { 1, 4, "QIC-40", "1100/550", 20, 365, 11680, 128, 32512 }, { 1, 5, "QIC-40", "1100/900", 0, 0, 0, 0, 0 }, /* ??? */ ! { 2, 1, "QIC-80", "205/550", 28, 100, 3200, 128, 19200 }, { 2, 2, "QIC-80", "307.5/550", 28, 150, 4800, 128, 19200 }, { 2, 3, "QIC-80", "295/900", 0, 0, 0, 0, 0 }, /* ??? */ { 2, 4, "QIC-80", "1100/550", 28, 537, 17184, 128, 32512 }, --- 152,158 ---- { 1, 3, "QIC-40", "295/900", 0, 0, 0, 0, 0 }, /* ??? */ { 1, 4, "QIC-40", "1100/550", 20, 365, 11680, 128, 32512 }, { 1, 5, "QIC-40", "1100/900", 0, 0, 0, 0, 0 }, /* ??? */ ! { 2, 1, "QIC-80", "425/550", 28, 207, 6624, 128, 19200 }, { 2, 2, "QIC-80", "307.5/550", 28, 150, 4800, 128, 19200 }, { 2, 3, "QIC-80", "295/900", 0, 0, 0, 0, 0 }, /* ??? */ { 2, 4, "QIC-80", "1100/550", 28, 537, 17184, 128, 32512 },
