unable to mount/unmount in ubuntu 10.04

[bilol]

Hi all,

I am unable to mount partition in ubuntu 10.04. Icons for different partitions are not coming within "Places".Every time I have to manually mount the partition or CD or DVD and manually unmount it.
Seldom it shows the partition icons within Places>Computer. Then the partitions are getting mounted upon double clicking its partition-icon. But I fail to unmount the partition as it throws the error "media/partition_name is not in the fstab (and you are not root)."
Need your help......

Open a terminal (Applications -Accessories - Terminal) and run these commands:

$ sudo fdisk -l

And post your results, then:

$ cat /etc/fstab

And post the results.

This information will help us to determine what is wrong.

I have done a fresh install of ubuntu 10.04 and this problem was not existing in ubuntu 9.10.
Sorry,right now I can not post you the output you wanted, because the concerned PC is in my home and now I am in office.

This is the intended output :

hi
yeah your fstab is looking strange. all the windows stuff is missing. why ? i don't now.
but follow those steps.
1. sudo mkdir /win01 /win02 /win03 /win04 ( or name that mount points as you want ).
2. insert into your /etc/fstab ( use your prefered editor for that ).
/dev/sdc1 /win01 ntfs defaults umask=000 0 0
/dev/sdc5 /win05 ntfs defaults umask=000 0 0
/dev/sdc6 /win06 ntfs defaults umask=000 0 0
/dev/sdc7 /win07 ntfs defaults umask=000 0 0
save the file
test your entries: sudo mount -a ( or mountall )
have a look if your entries where mounted: mount
if every thing is ok the filesystems will be mounted on every boot.
have fun
ciao

thanks a lot rnerwein....
to auto-mount my flash drive (FAT 32) what similar lines to be added in fstab?

[bilol]

your fstab is looking strange. all the windows stuff is missing. why ?

I don't think fstab need to have all info regarding different windows stuff.
In another Lynx-installed desktop( my office PC) there is no problem in auto-mount.Let me show you its fstab:
