About DriveMapper

  • When you create, delete, hide, and unhide partitions, your drive letters can change, causing applications not to run because application shortcuts, initialization files, and registry entries refer to incorrect drives. DriveMapper is a wizard that lets you easily update drive letter references.

    Important: DriveMapper does not change drive letter assignments; it only changes references to the drive letters, which are assigned by your operating system.

    You can run DriveMapper from the PartitionMagic main window. DriveMapper also runs automatically if the following conditions are all met:
    1. You apply changes to your system that affect drive letter assignments
    2. . You are running Windows 95 or Windows 98 ?Your hard disk contains only FAT or FAT32 partitions
    3. . You have no more than one CD-ROM drive and no more than one removable drive.
    If you are using Windows NT or Windows 2000/XP Professional as your only operating system, we recommend using the Change Drive Letter operation (Operation > Advanced > Change Drive Letter) rather than DriveMapper. Change Drive Letter lets you permanently set the drive letters for your partitions so that adding and removing partitions does not affect drive letters. Note that if you merge or split partitions, drive letters will change even if you are using Windows NT and the Change Drive Letter operation.
    If you have installed an alternative desktop on Windows 3.11 or Windows 95 with the desktop files residing on a different drive than the Windows system files, DriveMapper may not be able to adjust your paths. Because DriveMapper is a Windows program, it must have Windows loaded to run. If the drive letter has been changed for the drive that holds your desktop files, you may not be able to start Windows.

    Using DriveMapper with Multiple Operating Systems
    If you run multiple operating systems, you should reinstall applications rather than use DriveMapper. The following issues make using DriveMapper in a multiple operating system environment difficult and error-prone:
    1. Drive letter assignments are based on the file systems supported by an operating system. If you do not put all FAT32, and NTFS partitions after all FAT partitions, drive letters will change depending on the operating system currently running, and DriveMapper may be unable to correctly identify which changes should be made.
    2. Registry settings are changed for the current operating system only. If you manually run DriveMapper from another operating system, references in files will already be changed in the current operating system and further changes will introduce errors in the other operating systems.
    3. When DriveMapper is running, files contained in hidden partitions are not updated. If you are using multiple primary partitions for different operating systems, only the active primary partition may be visible. Thus, only files in that primary partition will be updated.

    Changing Drive Letters in the Correct Order
    You must change drive letter in the correct order to avoid destroying original references before they are used to make changes for other drive letters. For example, assume you have two partitions on your hard disk (a primary partition assigned the drive letter C: and a logical partition assigned D:) and a CD-ROM drive assigned E:. Suppose you create a logical partition between C: and D:. The drive letter of D: changes to E:, and the drive letter of E: changes to F:; however, references in certain files continue to reflect the old drive letter assignments. Using DriveMapper, you must first change the drive E: references to F: and then change the drive D: references to E:.
    When you make a change to your hard disk that adds drive letters, always change the highest affected drive letter first (drive E: in the previous example). Likewise, when you make a change to your hard disk that decreases the number of drive letters, always change the lowest affected drive letter first. Changing them in a different order changes source references needed to modify other drive mappings.
