sorry folks, forgot about this,
Ubuntu 9.10 has gParted by default to run from a LIVE DVD to re-format any pendrive in ext3/4 that windows cannot recognise,
download and burn to DVD, insert DVD into the drive and reboot PC
when your PC boots go to BIOS and set to boot from DVD/CD
select > try without installing
it will boot into Ubuntu . albeit a slower version as it is running from you DVD drive and RAM only,
you can still get internet access etc on it though, :)
@bazcfc1
if your PC can see the drive, try downloading ' photorec ' if its available for windows , it can recover most files from your external dish
do NOT try and save the recovered items to the same disc you are recovering from, it may [ WILL ] possibly overwrite the same file you are trying to recover
otherwise, use the above method with ubuntu, and insert another pendrive to download and run photorec to/from
