You can use testdisk q=

I assume you have a usb host cable so that you can plug the usb stick into the N810.

You will need to be root. http://nitstuff.appspot.com/dists/ch....0-4_armel.deb
then you can simply type "root" into terminal. (while you are at it grab the rest of the packages from http://nitstuff.appspot.com )

But anyway you could certainly use a live-cd. For your purpose, I'd get the GParted Live CD because it has testdisk installed. Download, burn as ISO to a CD/DVD.

Other good live-cds are Puppy, DSL, Sabayon (warning: bloated), and I used to recommend Knoppix but no longer.

As far as installations go. Fedora, Ubuntu, Linux Mint (Ubuntu) are good starts distro-wise.

Here is a guide for testdisk (I guess it also runs on DOS?) http://www.cgsecurity.org/wiki/TestD...table_recovery
