Hi there whoa199,
It would be nice to provide some more information on the issue.
Is this a laptop or a desktop?
Is the drive recognized by BIOS? You can check that out.
In case it is not, you can attach it to another system, as Martell1977 suggested. If the issue persists, then the HDD is dead.
Check Disk Management. If it appears over there, you can run some data recovery tool on it.
Let us know how this goes,
