My relatively new hard drive has completely stopped showing up in explorer after I was blowing dust out from inside the tower with compressed air while the computer was shut down. I made sure it was properly connected and even reseated the connections but that didn't change anything. It does seem to spin up when the computer turns on but it stops after a few minutes from what I assume is inactivity. I also tried looking for it in disk management and BIOS but it's not showing up in either of those. I then tried removing it from my computer and putting it into an external drive enclosure and plugging that into a different computer and just it does the same thing where it spins up but wont show up in file explorer or disk management. It seems to spin up fine with no weird sounds or anything but it quickly spins down again. When it's in the enclosure it sometimes spins up randomly but stops after about half a minute. I've read a couple of other threads of people with similar issues but none of their solutions worked for me.
