Aptiva - Unmovable Clusters in DEFRAG
Applicable to: United States
When running the DOS command DEFRAG, you may notice that a number of blocks in the disk map are marked with an X. These blocks contain certain system files that are not meant to be moved, since the system programs that use these files may expect them to be in a certain location or have a certain set of attributes.
Some of these files are for DOS, such as the operating system files. Some of them may be for Windows, such as a permanent swap file. Others may be for use with certain system functions, such as Rapid Resume. Still others may be for DOS utilities, such as Undelete Sentry, or used by application programs.
In general, there should be no problem with having X'ed areas in the disk map and there is usually no reason to be concerned about them. There are no built-in DOS functions or utilities that will assist you in identifying the actual files being used in these unmovable clusters. You can, however, use the DOS DIR command to at least be able to identify the files that may be somewhere in these unmovable clusters. The command format to use is:
DIR C:\ /AH /S /P
This command will search your entire disk, looking for hidden (unmovable) files, and produce an output to the screen that identifies the file name, its size, and the directory it is in. This command will not tell you which clusters are being used with the file; it will only provide information about the presence of such files.
In any case, it is not advisable to try to manually move these files or erase them. The files were set up this way for a purpose by the operating system or an application, and trying to manipulate these files so that the disk map "looks prettier" can lead to problems with the operating system or the applications that you use, resulting in a great deal of work to get the system back to normal.
There are third-party utilities that you can obtain at a local software store or computer store that may help you to identify these files and where they are located. These utilities may be complicated to use and understand, however, and may require an in-depth knowledge of the DOS file system and the organization of the DOS files.
