Without the disk connected, what is the output of
If there is any output, then you have copied the files to a directory called /media/usbdisk not the disk itself.

Just plug the disk in and it should appear on the desktop. Click it to open it, then copy your files to that place. Then right click the icon on the desktop and select unmount volume.

Thanks for the reply..

it throws error like it is already mounted on /media/usbdisk

If you have successfully unmounted a partition the kernel has to tell you that the device isn't mounted if you issue the same command again!

A partition, as in your case, can be unmounted by "umount" command either with
or
The kernel does not need to know the other parameters for unmounting it. It will still be shown in "fdisk -l" until you unplug the device or power down it.

In Linux you can manually mount and unmount a device (partition) any number of times. Issuing a command "ls /media/usbdisk" should tell you the status of it or if you open a file manager in the desktop you can actually see the files disappear and re-appear in front of your eyes.

to unmount the device forcefully use this replace hda2 with ur mount point
fuser -km /mnt/hda2
hope this helps
