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* lr-xr-xr-x 1 root root 32 Nov 27 2001 hda -> ide/host0/bus0/target0/lun0/disc lr-xr-xr-x 1 root root 33 Nov 27 2001 hda1 -> ide/host0/bus0/target0/lun0/part1 lr-xr-xr-x 1 root root 33 Nov 27 2001 hda2 -> ide/host0/bus0/target0/lun0/part2 lr-xr-xr-x 1 root root 33 Nov 27 2001 hda3 -> ide/host0/bus0/target0/lun0/part3 lr-xr-xr-x 1 root root 33 Nov 27 2001 hda4 -> ide/host0/bus0/target0/lun0/part4 lr-xr-xr-x 1 root root 33 Nov 27 2001 hda5 -> ide/host0/bus0/target0/lun0/part5 lr-xr-xr-x 1 root root 33 Nov 27 2001 hda6 -> ide/host0/bus0/target0/lun0/part6 lr-xr-xr-x 1 root root 32 Nov 27 2001 hdc -> ide/host0/bus1/target0/lun0/disc [greg@localhost /dev]$ cat /proc/partitions major minor #blocks name 8 0 8925000 scsi/host0/bus0/target0/lun0/disc 8 1 136521 scsi/host0/bus0/target0/lun0/part1 8 2 8787555 scsi/host0/bus0/target0/lun0/part2 22 0 244736 ide/host0/bus1/target0/lun0/disc 3 0 14114520 ide/host0/bus0/target0/lun0/disc 3 1 4200966 ide/host0/bus0/target0/lun0/part1 3 2 136552 ide/host0/bus0/target0/lun0/part2 3 3 16065 ide/host0/bus0/target0/lun0/part3 3 4 1 ide/host0/bus0/target0/lun0/part4 3 5 1052226 ide/host0/bus0/target0/lun0/part5 3 6 8707198 ide/host0/bus0/target0/lun0/part6 My /etc/fstab contains: /dev/hdc /mnt/ext2 ext3 nosuid,noauto,nodev,user 1 2 [greg@localhost /dev]$ mount /mnt/ext2/ mount: wrong fs type, bad option, bad superblock on /dev/hdc, or too many mounted file systems [greg@localhost /dev]$ sudo fdisk /dev/hdc The number of cylinders for this disk is set to 1757.
