I have a problem with my hard drive. It keeps trying to unmount itself, which means I can't read any files on it. The computer sometimes shows up in Disk Management and other times it doesn't show at all. I can see some folders on the file explorer screen, but if I click on them, I get an error saying "A device which does not exist was specified." This drive is a 2TB Samsung 980 Pro. I had this same problem before when I replaced that drive with my current one; it would come and go again. After completely reinstalling Windows, the issue is still there. I tried removing just one drive in case too many drives caused this, but it's still happening. I really don't know what could be wrong. I have already updated the BIOS and tried various Command Prompts to check drive health and system health. Restarting my PC seems to fix things temporarily, but the problem always comes back. I am not willing to do a full reinstall of Windows just so one drive works properly, though I'm not sure what else to try at this point. I already had two Samsung 980 Pro drives experience this with two separate motherboards too. I originally replaced that drive because I thought it was bad and later upgraded my motherboard but the problem stays the same now. I just really need a permanent fix so I can actually use the drive normally. My PC specs include: Ryzen 7 5800x, 64GB of DDR4 RAM at 3200MHz, an MSI MPG X570S Carbon motherboard with WiFi, a Corsair RM750X power supply unit, and a Gigabyte 4070 Ti graphics card. BIOS Version: 7D52v18. Samsung Magician software shows the drive is up to date.

I have updated my BIOS. What version do you have? You didn't say which slots the SSD is in on your board. If the SSD works fine, check Samsung's Magician app for updates. It might be better to put the drive in a different known good motherboard too.

Have you tried putting that drive into another M.2 hole? Your computer has three of them.
