Experiencing problems with a particular drive. It appears to unmount itself repeatedly, preventing access to any files. This occurs occasionally in disk management and sometimes not at all. While some folders appear in Explorer, selecting them triggers the error message: 'A device which does not exist was specified.' This drive is a 2TB Samsung 980 Pro. I've encountered similar issues before, where this same drive was replaced and then reappeared. After reinstalling Windows completely, the problem persists. I attempted to remove the drive in case it was too many drives, but it still causes the issue. I'm unsure what might be causing it. I've updated the BIOS and run various Command Prompts to check for drives and system health. Restarting my PC seems to temporarily resolve the problem, though it reappears later. I don't want to perform a full Windows reinstall just to get this drive working, but I'm unsure of other steps to take. This has happened with two different 980 Pro drives and on two separate motherboards. Initially, I replaced the 980 Pro due to concerns about its condition, and later upgraded the motherboard, yet the problem remains consistent across all units. I urgently need a lasting solution so I can use the drive effectively. BIOS Version 7D52v18. Checked Samsung Magician; drive is up to date. PC Specifications: Ryzen 7 5800x, 64gb DDR4 3200mhz RAM, MSI MPG x570s Carbon max Wi-Fi, Corsair RM750x PSU, Gigabyte 4070ti.
I've changed the BIOS settings.
What BIOS version do you have installed?
Please note which slots the SSD is being used in on the motherboard. If the SSD functions properly, check the Samsung Magician app for any available firmware updates. It might also help to transfer the drive to another known working motherboard.
Have you checked if the drive fits in another M.2 port? Your motherboard offers three M.2 slots.
