Windows update file can't be deleted

I used my hard drive to update windows because my laptop storage was full and then I accidently stopped windows update downloading. After that, the temp file windows created for windows update can’t be deleted. The root folder name is “asdf”, and there is one sub folder “bcde” and inside it, another folder named “ret” with no file or folder. I can’t delete with del command or rmdir command. And I can’t also run chkdsk command and it returns “unexpected error has occur”. Please help me solve the problem because I need to run chkdsk. I am starting to hear clicky sounds from hard drive.
