Today I by coincidence found myself with DVD-RAM disk.
Given that my DVD drive ( NEC DVD_RW ND-4571A 1-01 ) should be able
to work with DVD-RAM disks my curiosity got the best of me. Currently

I have to support writing files to a DVD-RAM in a Windows compatible mode.
Normally I would treat the thing as a slow HD and read and write at my
leisure, but Windows does not play nicely with UFS. So I came upon the
solution of writing an ISO image out

Howdy Hackers,
I have a DVD-RAM:
cd0 at sym0 bus 0 target 4 lun 0
cd0: MATSHITA DVD-RAM LF-D200 A120 Removable CD-ROM SCSI-4 device
cd0: 10.000MB/s transfers (10.000MHz, offset 16)
dd(1), newfs(8), mount(8) et. al. work just great on it, except
for newfs_msdos(8):
bash-2.05# newfs_msdos

I didn't realize it until we used it under 95/98, but the DVD-ram appears
to act like an MO drive. IE, one can add, remove, change files at will.
