if am not wrong you can recover them if you are under ext2 ( am not so sure about this ) when you do rm ,the file contents are not actually deleted ,they are still on your HDD its just the link that is deleted. Its always best to have a hardlink of your important data,so that if one file is deleted by mistake,the contents of the file can be still access via the other link.

See this if it helps,i never tried it myself.

First use dd to copy pen drive contents to a file on your hard disk:

Code:
mkdir /root/pendrive
dd if=/dev/sda1 of=/root/pendrive/pendrive.img
(Before running that command assure what device uses your pen drive).

Next try PhotoRec to recover data from pendrive.img file.

mkdir /root/pendrive
That should give him a "Permission Denied" (and this is his first post to LQ)

But it's a very good idea to take an image before you start playing with recovery tools (because your pendrive is un-written to, and therefore untouched by "recovery" tools )

A better way to do it might be:
Code:
dd if=/dev/sda1 of=~/pendrive.img                # copy the data over, bit-by-bit , so you have an image
mkdir ~/pendisk                                  # create a mountpoint for the image at /home/omraj/pendisk
mount -o loop -t ext3 ~/pendrive.img ~/pendisk   # mount the image
* ext3 will have to be changed if your pendrive's filesystem isn't ext3 ( most are FAT32 or type vfat - see man mount )

Now the image is mounted at ~/pendisk just as if it was a real disk. Run your recovery tools on that. If you mess up, you can always re-image your pendrive ( dd if=/dev/sda1 of=~/pendrive.img ) and start again.

Welcome to LQ!
