SUMMARY
=======
If Microsoft Defragmenter (Defrag) displays unmovable blocks (denoted by an "X")
and you don't have any hidden system files on your disk, you probably have one
of the following:
- Lost allocation units. To correct this problem, run CHKDSK /F before you run
Defrag. Or, if you have MS-DOS 6.20 or higher, run Scandisk before you run
Defrag.
- Executable files (.EXE or .COM files) that do not have the MS-DOS signatures
for .EXE or .COM files ("MZ" or "SC"). Old executable files, shareware files,
and some executable files used in copy- protection schemes do not have the MZ
or SC signatures.
NOTE: Defrag looks for *DOS.* and *IO.* to find all the system files on your
disk. Defrag does not move system files and represents them in the user
interface with an "X."
