Windows 10: Case of the Disappearing Drive

    Case of the Disappearing Drive

    Hey, folks --

    Has anybody else run into a recent problem with hard drives simply disappearing off your computer's radar?

    My wife's machine is running Win 7 (also 2 other OS's, but that's her main squeeze), and her third drive, a 2TB we use for backup, has vanished. I name those backup drives "Z", for convenience, and up until about two weeks ago, no problem. All of a sudden, the drive vanishes. Not "offline", it just doesn't exist in Disk Management at all. I tried pulling it out and checking it elsewhere, and the drive itself is fine. Put it back in, and the machine recognized it again. But a couple of boots later, it vanished once more.

    I thought maybe there was a hardware or cable problem, and was about to start troubleshooting there. But tonight, I see that my OWN machine (running Windows 10, most of the time) has the same exact problem. My "Z" drive is only 1TB, and suddenly it is just not there. The chances of BOTH machines having the same hardware problem at the same time are very remote, to say the least.

    So what I'm wondering is, was there something that came along in Windows Update recently that is causing issues like this? Something to do with drive letters further down the alphabet? I saw an earlier thread which pertained to very large drives (3-4TB), but it was an old thread and these drives are not that huge. Anybody have some insight here? I'm pulling my hair out!
