When you say it wont load, Im assuming you mean that the computer with this drive wont boot?
If so, I would yank out the hard drive, and hook it up to another computer. An external enclosure would be the easiest way if you have one then you just plug it in to another computer with usb, otherwise youd need to open up a second computer, and hook it up there. (external enclosures - here
- make sure you know whether the hard drive is IDE or SATA before buying one though)
If that doesnt work, it all comes down to how important the data is, and how much youre willing to do to get it back. If it comes to that, post here, I'll toss out a few ideas.
