Large secondary drives

Specs: Windows NT4.0, 2x Pentium Pro 200MHz, 64MB
I have two PCs running Windows NT (one NT4, one NT3.51). I want to install additional (non-system) hard drives in both, but I know NT natively has a very small partition limit. I have successfully installed a small reg edit in Windows 2000 to overcome the 137GB limit, is there a similar technique to install large drives in earlier NT versions? How large a partition would I be able to install in this earlier form of NTFS?

This is old, but...

You need to enable "ATA-6" 48-bit LBA in NT 4.0 in order to exceed 137GB. The default LBA for NT 3.x, NT 3.5x, and NT 4.0 is 28-bit.

Here it is: Universal ATA driver for Windows NT3.51/NT4/2000/XP

Please note this solution has not been tested by me and I cannot be responsible for any loss that may arise out of the use of this product!

Here is some additional information: Windows NT 4.0 Large HDD Information

Let us know if this works.

NT4 and NTFS have always supported large drives. The problem is that your hardware, BIOS, or drivers may not.
