Hi folks,
Silly question, perhaps, but I wasn't able to figure out source of the
problem myself...
I used rarely magneto-optical disks to transfer data to/from Windows
machine. For compatibility, disks used HDD FAT16 format.
About a month ago the disks began to refuse to mount under -current:
# cat /var/run/dmesg.boot |grep '^da2'
da2 at ahc0 bus 0 target 6 lun 0
da2: <FUJITSU M2513A 1700> Removable Optical SCSI-2 device
da2: 10.000MB/s transfers (10.000MHz, offset 10)
da2: 606MB (310352 2048 byte sectors: 64H 32S/T 151C)
# fdisk /dev/da2
******* Working on device /dev/da2 *******
parameters extracted from in-core disklabel are:
cylinders=151 heads=64 sectors/track=32 (2048 blks/cyl)
parameters to be used for BIOS calculations are:
cylinders=151 heads=64 sectors/track=32 (2048 blks/cyl)
Media sector size is 2048
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:
The data for partition 1 is:
sysid 6 (0x06),(Primary 'big' DOS (>= 32MB))
start 32, size 309216 (603 Meg), flag 80 (active)
beg: cyl 0/ head 1/ sector 1;
end: cyl 150/ head 63/ sector 32
The data for partition 2 is:
<UNUSED>
The data for partition 3 is:
<UNUSED>
The data for partition 4 is:
<UNUSED>
# mount_msdosfs /dev/da2s1c /mnt
mount_msdosfs: /dev/da2s1c: No such file or directory
Indeed, there is only /dev/da2 node now.
But how can I tell the devfs system to create needed nodes?
