The ENHDISK.SYS device driver made it possible to access multiple MS-DOS
partitions created by earlier versions of the MS-DOS FDISK utility on fixed
disk drives. ENHDISK.SYS was used under Compaq MS-DOS 3.2 and earlier to
provide partitioning support for hard disks greater than 32 MB.
ENHDISK.SYS had to be the first device driver installed in the CONFIG.SYS
file. This was done to ensure consistency for drive assignments through all
the utilities that support partitioned drives created by earlier versions
of the FDISK utility.
Compaq technical support recommends backing up the hard drive prior to
running MS-DOS 5.0 or later upgrade. If the upgrade has already been
performed, and the extended drives are inaccessible, use the MS-DOS
UNINSTALL disk to restore the previous version of MS-DOS.
Take the following steps with the old version of MS-DOS installed:
• Back up all necessary data on the hard drive.
• Repartition the hard drive with the MS-DOS 5.0 FDISK command.
• Format all drives on the hard disk. For example:
• Restore necessary data.
