My configuration is: IBM 350/486 DX100 32 MB with Adaptec 2940 PCI SCSI card. The tape drive is recognised at bootup as follows: (ahc0:3:0): "TANDBERG TDC 4100 J04:" type 1 removeable SCSI 2 st(ahc0:3:0): Sequential-Access density code 0x0, 512-byte blocks, write-enabled However when i go to access the tape drive (using the test suggested in the news group archive): dd if=/dev/zero of=/dev/rst0 count=100 objs=512 I get the following error message: st0(ahc:3:0): ILLEGAL REQUEST csi: 0,8,0 asc:24,0 Invalid field in CDB fielod replacement unit 2 st0: Cannot set selected modest0: oops no queued .. It then goes on to repeat the operation a number of times until I Ctrl^c out. I previously had FreeBSD 2.0.5 installed (on a 386/Adaptec 1542CP) which came up with the same message when I tried to access the tape drive (i also get this with tar). Any suggestion/help would be appreciated. Thanks for any help. John Hartley. jbh@labyrinth.net.au Graphica Software Pty. Ltd.
