hi,

i tried to mount a msdos filesystem (preformated) on a maxtor
onetouch 200gb usb harddisk.

but=20

  mount -r -t msdos /dev/da1s1 /mnt

gives the following error:

mountmsdosfs(): disk too big, sorry

the disk is detected fine:

umass0: Maxtor OneTouch, rev 2.00/2.00, addr 2
umass0: Get Max Lun not supported (STALLED)
da1 at umass-sim0 bus 0 target 0 lun 0
da1: <Maxtor OneTouch 0200> Fixed Direct Access SCSI-0 device=20
da1: 650KB/s transfers
da1: 194480MB (398295040 512 byte sectors: 64H 32S/T 63408C)

Information from DOS bootblock is:
The data for partition 1 is:

        beg: cyl 0/ head 1/ sector 1;
        end: cyl 214/ head 254/ sector 63
The data for partition 2 is:
<UNUSED>
The data for partition 3 is:
<UNUSED>
The data for partition 4 is:
<UNUSED>

is this a known problem? under linux mounting the fs works
flawlessly. seems like this is a limitation of the freebsd msdosfs
driver. is it possible to port the driver from linux?

thanks for your time
