Hello,
I didn't try devfs for a long time, I wasn't using it because of a problem
I hadded, but didn't remember which one...
Now, I can remember: I can't access my IDE zip which is normaly (without
devfs) under hdc.
Could someone explain me what I am doing wrong?
I can't test it with a partitionned ZIP as all my ZIP have no partitions.
I give here the output of somes commands (under 2.4.16 with devfs):
[greg@localhost /dev]$ ll hd*

Gregoire,
I'm working (right this minute) on devfs support for ide-floppy
but... your problem doesn't look like an ide-floppy/devfs problem.
On my system, the output from fdisk on a zip 250 looks like
[root@zoltar ide]# fdisk /dev/hdf
Command (m for help): p
Disk /dev/hdf: 64 heads, 32 sectors, 239 cylinders
Units = cylinders of 2048 * 512 bytes
Device Boot Start End Blocks Id System
/dev/hdf4 * 1 239 244720 6 FAT16
so your hdc is a hard disk, not a zip.
Try changing your fstab to point to ide/host0/bus1/target0/lun0/disc
instead of /dev/hdc

Well, I have of course tried this (not in fstab, but in
sudo mount -t ext3 /dev/ide/host0/bus1/target0/lun0/disc /mnt/ext2/
My ZIP 250 isn't shown at all correctly: all infos are the one from my
first HD hda... even if I call /dev/hdc or
/dev/ide/host0/bus1/target0/lun0/disc...
If that's could help, some more infos:

Hello,
I am also interested of any way I could access my ZIP having devfs, but
I don't have anything against making a mknod or whatever needed...
Thanks you very much,
Grégoire

Oups, sorry for the posts:
sudo MAKEDEV -d /tmp/esa hdc
sudo mount -t ext3 /tmp/esa/hdc /mnt/ext2/
Works just great ;-)
