Does anybody know how to format a DVD-RAM disc with FAT32 in FC3? If I try
to format the whole disc without partitioning, I get:
$ /sbin/mkdosfs -F 32 -n DVDRAM1 -v -I /dev/hdc
mkdosfs 2.8 (28 Feb 2001)
mkdosfs: unable to get drive geometry for '/dev/hdc'
If I partition the disc, then fdisk -l shows the partition but there's no
/dev entry for it:
$ /sbin/fdisk -l /dev/hdc

Did you try working with a sector size of 2048? (-S parameter on mkdosfs)
I know a lot of devices (like MO disks and most DVD-RAM) work with 2k sectors
rather than 512 as is the default assumption a lot of times.
CD-ROMs also use a 2048-byte sector size. AFAIK, only disks actually
use 512-byte sector sizes. Well, way back when, Sun used a 512-byte
sector size on CDs, too (Sun SPARC SLC, etc.). I never did figure out
why. Fortunately, I had some old NEC Multispin CD drives that could be
jumpered either way, so I put on a switch.
