problem accessing the CD-Rom??



Hello!

on my Laptop i have the problem, that i can't access the
dvd-reader/writer....

i put in  a tested dvd, try to mount it, and get:
mount /dev/hdc /mnt
mount: you must specify the filesystem type

huh?

mount -t iso9660 /dev/hdc /mnt
mount: /dev/hdc already mounted or /mnt busy

laptop:~# lsof /mnt
laptop:~# 
laptop:~# lsof /dev/hdc
laptop:~# 

ehm...

strangely i see the drive in /proc/ide, on boot i get:
Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2
ide: Assuming 33MHz system bus speed for PIO modes; override with
idebus=xx
ICH5: IDE controller at PCI slot 0000:00:1f.1
PCI: Enabling device 0000:00:1f.1 (0005 -> 0007)
ACPI: PCI interrupt 0000:00:1f.1[A] -> GSI 18 (level, low) -> IRQ 193
ICH5: chipset revision 2

hdc: HL-DT-ST DVD-RW GWA-4040N, ATAPI CD/DVD-ROM drive
ide1 at 0x170-0x177,0x376 on irq 15

a grep on lsmod shows that the correct modules are loaded:
ide_cd                 42656  0 
cdrom                  40732  1 ide_cd
ide_generic             1408  0 
ide_disk               19296  6 
ide_core              139940  4 ide_cd,ide_generic,piix,ide_disk

just to be sure that no system like autofs etc are installed:
laptop:~# ps aux |grep auto
root     22117  0.0  0.0   1548   476 pts/5    S+   09:02   0:00 grep auto
laptop:~# 

i have discover installed though....

i am at the end of my clues, don't know what is going wrong and how to
fix this....

any hint welcome!
