Try to see if you can delete them without errors by booting into safe mode.
One way to boot into safe mode is to
- Press Windows + R
- Type
msconfig
- Go to the
boot
tab and select safe boot
- Select any other options and press OK and restart the computer
If you can delete them there and restart back into normal mode, the problem may be fixed. If not, additional troubleshooting may be required.
Some possible causes of the issue may be that the hardware is failing or the OS cannot map properly to the hardware. If you have other drives, or perhaps a USB drive, check for the same error.
Unfortunately, I can't find any resources that may identify the root cause.
