Hi-MD as usb drive (*BSD)

Ok, so I love the format, and store all sorts of data on mine as well as the music. Unfortunatly my OS of choice as a network admin is OpenBSD which doesnt seem to play happily with the way Hi-MD represents itself as a umass device. Have any of you managed to figure out the drive geometry that might make the hi-md work? It would realy rock to have hi-md working on all the umass aware OSs that I know. Also on the drive geometry issue, have any of you tried to use a non Sony cardreader->usbdrive copier? This would also be quite nice, being able to dump photos to MD where (since I carry them with me in the feild) I wouldnt have to worry about anything damaging them. Once again a plus for the only format that is cheap, rugged and heat resistant.

Thanks in advance for your time,

Robert Szasz

Havn't tried it on BSD but should be same for most linux distros, ive mounted it on RH a few times:

mkdir mount_pt # eg /mnt/hi-md

mount -t vfat /dev/sda mount_pt

cd mount_pt

The usb drive may come up as a different device so if that doesnt work try /dev/sdb, /dev/sdc...

Hope this helps

i guess it is a quirk of the obsd msdos mounting then.. it does create the sd0 device. but the msdos mount command fails, and dd seems to make four copies of each sector on read. Could you be so kind as to post the output of disklabel?

This is on FreeBSD 6 with a fresh 1GB disc:

umass0: at uhub0 port 1 (addr 2) disconnected

(da0:umass-sim0:0:0:0): lost device

(da0:umass-sim0:0:0:0): removing device entry

umass0: detached

umass0: Sony Hi-MD, rev 2.00/1.00, addr 2

da0 at umass-sim0 bus 0 target 0 lun 0

da0: <SONY Hi-MD WALKMAN 1000> Removable Direct Access SCSI-0 device

da0: 1.000MB/s transfers

da0: 964MB (494023 2048 byte sectors: 64H 32S/T 241C)

bsdlabel errors with no valid label found, but mount_msdosfs does mount the raw device /dev/da0

Weird. I'll see what happens if I format the disc with Windows.
