How to Run chkdsk on a disk without a drive letter

Open a command prompt.

Execute the mountvol command which will tell you all the volumes on your system and give you the GUID of them.



Windows will give the GUID if it’s has valid and recognized partition.

Then run CHKDSK in this fashion:

chkdsk “\\?\Volume{eb38d03c-29ed-11e2-be65-806e6f6e6963}”

Use /f and other switches as appropriate.
