name Entry has a bad size.
The directory specified in the message has an entry with a bad file size.
Run the chkdsk command with the /f switch to fix the problem. Keep in mind that you should not run chkdsk /f on an NTFS partition without first doing a backup. If there is a problem with any of the metadata files, the index entries for them will be deleted and you will not be able to reboot the system.
