If you do that you will not have any chance to recover your data. It will delete evet thing on your drive. On the other hand your drive might be usable again afterwords

Subject: Re: NTFS drive wont mount - "unknown filesystem"?

Hi Karl.

Thanks for getting back so quick, but I have a little problem with
that. The partition on the broken hard drive is bigger than my
internal hard drive, or any hard drive that i own. That might not work
so well. Also, I'm not too good with opening hard drives or computers.
I'm good at fixing software, but I'm no use for fixing broken

However, I noticed in GParted that it allows me to "Format as NTFS". I
didn't actually do it, but I was wondering what would happen if I did.
Does format strictly mean that it will erase everything on the hard
drive, or will it just make the hard drive into an NTFS partition? If
it just makes it into an NTFS partition, then I could probably try
that, right?
