Error encountered when Windows 10 SSD fails to recognize the device under heavy system usage.
Error encountered when Windows 10 SSD fails to recognize the device under heavy system usage.
Hi! I've noticed this strange problem lately with my M.2 SSD, where it occasionally stops working temporarily. Windows sometimes shows an error saying "A device which doesn't exist was specified" when trying to access files on the drive. This usually only affects certain folders, and I can still use the rest of the system normally. After restarting, the drive disappears completely even from the BIOS, and I've only managed to fix it by unplugging the power cable and holding the power button for a few seconds. Once I do that, it comes back and works fine again.
This issue has happened occasionally, especially when running a demanding AI tool that can cause system stress and trigger this drive error.
I've tried the following:
- sfc /scannow - no errors
- chkdsk - no errors
- updating and reinstalling drivers on all devices
- re-seating the SSD
- relocating the SSD to a different slot
Still nothing has resolved it. It's not a major problem, but it's unusual and I'm curious if others have faced similar issues.
System details:
- Ryzen 3700X
- RTX 3070 TI
- Asus TufGaming B550 Plus
- 4 x 8 Gb 3200MHz HyperX Fury DDR4
- Samsung 990 Pro 2Tb PCIE SSD (the one in question)
- Windows 10 Home OS
I observed that when under heavy load, my 3vcc voltage in hwinfo falls significantly below the required level (sometimes even dropping under 3v). It looks like my inexpensive power supply is having trouble maintaining the voltage during high demand. Also, reducing the GPU's power limit to 50% helped avoid both SSD crashes and voltage fluctuations.
