SUMMARY

The device driver LDRIVE.SYS provided with some Future Domain hard drive controllers is incompatible with MS-DOS versions 5.0 and later. To install MS-DOS 5.0 and later onto the hard drive, it is necessary to back up the hard drive, repartition and reformat the drive under MS-DOS 5.0 or later, and restore backups. The device=LDRIVE.SYS line should be removed from CONFIG.SYS.

LDRIVE.SYS is intended to provide greater than 32 MB logical drives under MS-DOS 3.3 and earlier. It provides this service by using a technique called logical sectoring in which sector sizes greater than 512 bytes are used. Without a driver such as LDRIVE.SYS, MS-DOS is not capable of reading these disks. This necessitates reformatting the disk using MS-DOS FORMAT to make the disk usable without special drivers.
