Hard Drive No Longer Available

Hey all,

So yesterday my laptop died, got the folder with the question mark in it. I took the hard drive out, put it in an enclosure, and used disk utility to repair it. Put it back in, still nothing.

I pulled it out again, backed up my files, then reformatted it and put it back in. Still nothing. Any suggestions on what the problem might be?

No weird sounds from the hard drive, and the enclosure is recognizing it no problem. Is it really the hard drive or is something else in play here?

Thanks!
