I reduced my external HDD capacity to 300MB

My laptop has been giving me a black screen with a movable cursor upon starting up. The problem started after it ran out of power while in hibernation. I have no system restore points or back ups of my system so I tried to fix it without losing my data, but when I tried to clone my disc onto my external HDD the power ran out yet again (yes, I'm quite careless) quite early into the process, leaving my external HDD with 300MB total space.

I've been looking for ages now for a way to restore it to its original capacity and have found a lot of info on fixing internal HDD's, but not external ones. I tried HDD Capacity Restore Tool but it wouldn't recognise any HDD's on my computer. I tried seatools, but it recognise USB. Then I found something called USBASPI which should make DOS work with USB, though I'm not sure if it works the way I need, and if so, how to do it, since the only related help I've found online is about putting Seatools on a USB drive instead of a CD.

I got my hard drive into this mess by using software called Copywipe which was on Ultimate Boot CD. I'd greatly appreciate any help fixing this so I can then get onto fixing my laptop, cheers.

But the disk is well recognized on BIOS?
