We are purchasing an Everex 386/25 machine with a 676 MB Micropolus hard disk. This will have an Esti interface. We have a problem with formatting it with MS-DOS 4.01. Dos is only recognizing a maximum of 512 M. Does anyone know how to solve this problem? It was suggested that we switch to UNIX, but we have 4 other machines running in DOS, plus various specialized applications.

Compaq DOS 3.31 has a special version of format (or fdisk?) that allows hard disk capacities in excess of DOS 512M limit.

The solution is to get a disk controller which does TRANSLATION. This controller will make DOS believe that your disk has less cylinderss and more sectors per track. This translation is transparent to DOS and will require only the proper low level formating of the disk. -- cj
