I have an LS-120 drive at IDE1 master:
root> dmesg | grep afd
afd0: 120MB <LS-120 CSMO 05 UHD Floppy> [963/8/32] at ata0-master using PIO2
How can I put a UFS on a 1.44 MB diskette? The following
operations result in an error.
root> fdformat -f 1440 -c 80 -s 18 -h 2 -S 2 /dev/rafd0
fdformat: not a floppy disk: /dev/rafd0
root> disklabel -w -r /dev/rafd0 fd1440
disklabel: ioctl DIOCWLABEL: Operation not supported by device
root> newfs /dev/rafd0
newfs: /dev/rafd0: '0' partition is unavailable
root> fdisk -i /dev/rafd0
******* Working on device /dev/rafd0 *******
parameters extracted from in-core disklabel are:
cylinders=80 heads=2 sectors/track=18 (36 blks/cyl)
parameters to be used for BIOS calculations are:
cylinders=80 heads=2 sectors/track=18 (36 blks/cyl)
Do you want to change our idea of what BIOS thinks ? [n]
Media sector size is 512
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:
The data for partition 1 is:
<UNUSED>
Do you want to change it? [n] y
Supply a decimal value for "sysid (165=FreeBSD)" [0] 165
Supply a decimal value for "start" [0] 1
Supply a decimal value for "size" [0] 2880
Explicitly specify beg/end address ? [n]
Adjusting partition to start at a cylinder boundary

start 0, size 2880 (1 Meg), flag 0
beg: cyl 0/ sector 1/ head 0;
end: cyl 79/ sector 18/ head 1
Are we happy with this entry? [n] y
The data for partition 2 is:
<UNUSED>
Do you want to change it? [n]
The data for partition 3 is:
<UNUSED>
Do you want to change it? [n]
The data for partition 4 is:
<UNUSED>
Do you want to change it? [n]
Do you want to change the active partition? [n]
We haven't changed the partition table yet. This is your last
chance.

I'm able to create a msdos filesystem:
root> newfs_msdos /dev/rafd0
/dev/rafd0: 2840 sectors in 355 FAT12 clusters (4096 bytes/cluster)
bps=512 spc=8 res=1 nft=2 rde=512 sec=2880 mid=0xf0 spf=2 spt=18 hds=2 hid=0
I can also put files on a diskette using tar:
root> tar cf /dev/rafd0 CASIMIRHOST GENERIC LINT
root> tar tf /dev/rafd0
CASIMIRHOST
GENERIC
LINT
