After you install the FAT32 file system on a drive that uses OnTrack DiskManager version 6.03 or 7.04, one or both of the following symptoms mayoccur:
  • All drives use MS-DOS compatibility mode.
  • The computer seems to take an unusually long time to boot.
Dynamic Drive Overlay is unable to find files in the root folder thatit needs to start correctly.
To resolve this issue, use either of the following methods:
  • Configure Disk Manager to avoid searching the root folder for overlayfiles, or upgrade Disk Manager to version 8.0 or later.

    For information about or assistance with configuring Disk Manager, pleasecontact OnTrack Technical Support.
  • OnTrack has an upgrade patch available at the following Web site that resolves this issue without the need to change overlay settings using Dm.exe:Microsoft provides third-party contact information to help you find technical support.

More information
Dynamic Drive Overlay makes calculations for the starting root foldercluster based on FAT12 and FAT16 volumes and returns a value of zero forFAT32 volumes. This occurs because of changes made in the root folderstructure. The overlay software searches all possible clusters in the rootfolder for its overlay files.

Configuring the Disk Manager Dynamic Drive Overlay software to avoidsearching the root folder causes Disk Manager to not hook the DOS ArenaChain, forcing Disk Manager to load low in conventional memory.
