When you try to gain access to an NTFS file system volume, you may receive the following error messages at the command prompt or in Explorer: X:\is not accessible. There is not enough space on the disk.
This problem occurs because the NTFS volume has an invalid or damaged record in either the $UsnJrnl file or the $LogFile file. Both of these files are internal files that are used only by NTFS; Chkdsk does not check the integrity of these two files. Chkdsk ensures only that the Master File Table (MFT) has entries for these files and that the entries are valid entries.
