Installing Windows NT on a Hard Disk Configured with EZ-Drive

• Microsoft Windows NT Workstation versions 3.5, 3.51
• Microsoft Windows NT Server versions 3.5, 3.51

SYMPTOMS

If you install Windows NT on a Conner hard drive configured with the EZ-Drive utility, one of the following error messages appear:

Hard drives are not usable by NT

-or-

NT cannot access the partitions prepared by DOS

CAUSE

This problem occurs if the Windows NT Compatibility Mode (also called Floppy Boot Protection in later versions of EZ-Drive) is not enabled for a computer using a hard drive that does not have logical block addressing (LBA) capability. If the system has LBA capability, then the EZ-Drive Overlay Manager does not need to be used.

RESOLUTION

To correct this problem, enable the Windows NT Compatibility Mode. To enable the mode, do the following:

1. Backup the contents of your hard disk.



2. Insert the EZ-Drive disk in the floppy drive and type "EZ" (without the quotation marks).



3. From the menu list, select Windows NT Compatibility Mode.



4. Save and exit the EZ-Drive utility.



5. Reboot the computer. You do not need to repartition or reformat the hard disk. If you wish to remove the EZ-Drive Overlay Manager once it has been installed and the LBA options enabled in the CMOS, type the following at the MS-DOS prompt:

   FDISK /MBR
