hellow to all..
i am trying to install windows NT 4.0 on 80gb harddisk , i recive error msg that it is too big the partion , i try to install it on 40gb , also i recive the same msg ...
the install only works on 4gb , and it is so slow !
how can i resolve the problem ..
help thank's ...

First I presume you HP BIOS supports these hard drives, second 128MB of memory is ideally the minimum when all the updates have been installed. Yes NT4 was developed in the days when 4GB HDD were common, see the following:

so how can i install maxsimum disk space on my system ?

read the linked articles:

http://support.microsoft.com/default.aspx?scid=kb;en-us;138364

After the system is installed, use drive manager to create data partiton/s using NTFS or FAT file systems to utilize the maximum disk space.

Very bad advice.

Guess folks have forgotten the 7.8gig bios/ntfs boot bug in NT. If system/boot partition exceeds 7.8gig the system can be rendered nonbooting due to the bios's inability to address the boot files if they get moved beyond 7.8gig.

I developed this technique in 1999 to get NT to larger hard drives and not fulfull the conditions for the bios boot bug. See here

I've always found partitioning the drive elsewhere (eg, slaving it to existing NT SP6 system and using disk administrator to create the partition) and using the atapi driver (press F6) here:- http://www.htl-steyr.ac.at/~morg/drivers/NT_Atapi/ during the install process (so install can recognise disks larger than 7.8GB) works for me.

Steve recognizing the disk was never a problem dispite the hipe since sp3 for NT. No sp4 atapi driver required [doesn't work on some systems anyway]

Again it comes back to if you exceed 7.8gig for system/boot you can end up with a nonbooting system.

I consider that really bad especially for a server in production.

Here is my two-pennies worth, i wonder if anyone will read it.

i have installed NT4 on a 40Gig HD with no problem. It is true that when you first install NT it will only recognie the 7gigs you mention, but after putting SP6 on you can recover the rest as one seperate drive in an extended partition using disk administrator. i have seen in a commercial environment a server with a 6gig primary disk and a 40gig slave disk (NTFS ). i agree that i am surprised that these is such a small limit for NFTS for NT4. in the commercial company i mention above, they have one server, and both disks are practically full up, and they don't know what they are going to do next. Add another server i suppose. But then again....
i have two external hard drives that are NTFS, one is 160gig and the other is 250gigs. i know that only XP SP2 can read them, but surely there must be something for NT4, but i don't know what it is.
if there is a program to read FAT32 drives, then there must be something for NTFS for large drives as well.

Hey I will read it :-)

NTFS is limited to 16 terabytes even with NT. You don't need an extended partition since you can use a primary [you are allowed 4 primary's per disk]. You can make any size partition for boot you want. Don't forget now in ms-speak boot is where winnt folder resides and system is where boot.ini resides.

The ntfs/bios bug I refer to only involves system or when the same partition is used for system/boot. Don't exceed 7.8gig for system or system/boot.

There are no other limitations after that for NTs ntfs. I have had a 65gig raid array running on NT for 6 years now. Still running strong [did have to replace/upgrade the drives]
