Hi again, I've managed to pick up a SONY MO drive and having trouble using it. Can anyone help with this? Scsi reports it as a SMO-E501-08 drive, 1024 byte sectors, 307MB, 9830 cyl, 1 head and 32 sectors per track. I've compiled a kernel with the od device and the devices are in /dev. I can also put a disklabel on it but can't seem to get a filesystem installed :( Using newfs without a disk type gives an error "can't read disklabel, disk type must be specified." If I construct a disktab entry (attached below), and put a label on the disk, I get an error using newfs: "write error: 314536" "wtfs: Invalid argument" Using: newfs -S 1024 -s 150000 -T SONY /dev/od0c seems to work (maybe the media is only 150Mb) but when I try to mount the disk, the mount point disapears :) % cd / % ls -ld mnt drwxr-xr-x 2 root wheel 512 Apr 17 18:08 mnt/ % mount /dev/od0c /mnt % ls -ld mnt ls: mnt: No such file or directory <grin> System is 2.2.1-RELEASE on a PCI board (486dx100) with 1542C isa scsi adaptor. I can't find anything of use in dejanews or the questions/hackers lists.. I'll attach the output from disklabel -r below also.
