Purchased this drive about a year ago. Its a 750GB OWC SSD. Earlier today I put my computer to sleep with absolutely no problems, opened it up a few hours later and the hard drive isn't recognized anymore (I have one drive as the boot drive, that one is fine, but this one is my user folder/data). Is this just a dead drive or is there any other explanation or anything I can try to get it back up and running. Thanks.
