D drive

Hi,

Based on the details you have provided us, it appears that there might be some corrupted contents on the said partition. We can also consider that this is caused by a virus.

• Type Command prompt in the search bar.
• Type-in the following command:
  
  attrib -h -r -s /s /d D:\*.*

If you think that there is nothing important stored in it, then we suggest that you reformat your D drive so that you can use the free space for important files.

D: drive disappeared

Number 2 is my graphic card. Only no 1 is the drive.

I did as you suggested: unplugged the two cables, booted the PC, restarted, turned off, re-attached the two cables and booted again. And we're back to square 1.

Note: whilst I had the drive disconnected, the 'unknown unit' did not appear on the list of drives.
