I recently bought a Seagate 5 TB external hard drive. The point was to use it to move stuff around so I could back things up. Ironically, this new drive failed with some non-backed up stuff on it. What happened was, my computer wouldn't always recognize it when I plugged it in to the USB port. It was periodic and then it started working fine for about 2 weeks. Then it stopped again and now, sometimes the computer will recognize it, but not let me open stuff up. I tried a different cable and 2 other computers including a Mac (with the proper software for Seagate). No dice. I tried using Disk Management, but since the drive isn't even recognized, there's not much I can do with the various remedies online like CHKDSK and Scannow, etc. I've thought about trying the 'freezer method,' but I think that's a last resort. Before I spend nearly $400 to recover it, what other options do I have? Thanks.
