mount/umount

[nogagplz]

When ever I try to eject a CD/DVD, it comes up with an error saying:

"Unfortunately, the device system:/media/hdc (/dev/hdc) named 'Kubuntu 7.04 i386' and currently mounted at /media/cdrom0 could not be unmounted. The following error was returned by umount command:
umount: /dev/hdc: not mounted
umount: /media/cdrom0: must be superuser to umount
umount: /dev/hdc: not mounted
umount: /media/cdrom0: must be superuser to umount"

Prior to this, I could just hit the button on the drive, and be on my way. Now I have to type "sudo eject /media/cdrom0" or "sudo mount /media/cdrom0".

Any ideas on how to make it how it used to be?

Re: mount/umount

guess we need to take a closer look at your set up.
pls, eject any cds you should have mounted and
post the result of the following commands:

ls- l /dev/hd*

ls -l /dev/cd*

ls -l /media

cat /etc/fstab

hopefully i haven't forgotten anything.

i could be it's just a matter of removing this /media/hdc,
which doesn't sound right...

but let's see...

Not as technical as jankushka!

How do you try to eject disks?

Do you see an icon of the disk on your desktop and does it have a green mark at the bottom corner. The green mark means it it mounted.

RIGHT click on the icon and choose "Eject". What happens?

As for clicking eject in the context menu, the first time it did nothing, then it gave the same error that I got from physically pressing the button.

Re: mount/umount

two things:

a) i actually need "ls -l" not "ls -1"

b) in your /etc/fstab, you have 2 entries for /dev/hdc
this is not good.
remove the one for /media/cdrom1.

Sorry for the mixup with 1 and l >.>;

Re: mount/umount

all right...
sorry i'm a bit in a hurry, so i'll try and keep it simple.

it appears you have 2 cd drives (or 1 cd and 1 dvd): is this correct?

your /dev/cd* both point to /dev/hdd.
the entry in your /etc/fstab is for /dev/hdc.

you have to get these right, i think.

also (for cleaning purposes) you may remove "disk" and "disk-1" from the /media folder.
mount points for removable media are created/removed dynamically.

let us know how it goes.
if you need me to clarify anything, pls, also let me know.
