Ok so here's a weird one. I have a couple mismatched drives that I use for archival purposes. One of them is a Seagate 1.5TB drive and it only spins up if it's standing vertically (ports facing up). If I lay it down normally, it spins up for a fraction of a second, clicks, shuts down, and starts over. SMART tests are perfect, and Seagate SeaTools says the drive is perfect.
The drive has been secured with all four screws in a case for the past year or so. It just hasn't been plugged in. I mean, I'm not worried, because I can just pull all the info off and put it on a new drive, but I'd like to get it working again.
