I've had problems getting NT Server 4.0 to recognise that I have a 17GB HDD! To install NT in the first place, I created a FAT16 partition (using Fdisk with large disk supprot turned off, and then formatting from DOS), and then converted this to NTFS during the installation. Now it's up and running, Disk Administrator thinks that the disc is only 8056MB (ie, the 2GB system partition + 6GB of unpartitioned space)! How do I convice it to *see* the full 17GB?

Thanks

SYMPTOMS

During the installation of Windows NT to an 8 gigabyte (GB) or larger IDE hard drive,
the computer may stop responding (hang) during the format portion of setup. If the
drive was previously formatted as FAT and designated to be converted to NTFS, the
computer may hang during the conversion process. Other symptoms include the drive
taking an extremely long time to format or Windows NT not recognizing the entire size
of the drive.

CAUSE

The Microsoft supplied generic IDE driver (Atapi.sys) may not be fully compatible with
drives larger that 8 GB. This issue only affects IDE-based drives 8 GB and larger.

RESOLUTION

Windows NT 4.0 Service Pack 4 (SP4) has a new Atapi.sys file that allows the drive to
be formatted during setup of Windows NT. SP4's Atapi.sys can also access space
beyond 8 GB on these IDE drives.

The system parition (boot partition) is still limited to 7.8 GB whether an updated version
of the Atapi.sys file is installed or not. For more information, please see the following
article in the Microsoft Knowledge Base:

Q114841 Windows NT Boot Process and Hard Disk Constraints

NOTE: The system board BIOS must support and recognize drives larger than 8 GB before Windows NT can access the entire drive. You can verify this ability by entering into the BIOS or contacting your system board manufacturer.

If you are using Windows NT 4.0 Workstation, Server, or Terminal Server, follow these
instructions:

1.Download the updated Atapi.sys from Microsoft's FTP server

ftp://ftp.microsoft.com/bussys/winnt/winnt-unsup-ed/fixes/nt40/atapi/ATAPI.EXE

and copy the file to a blank floppy disk. Run Atapi.exe on the diskette and the
new Atapi.sys file will be extracted to the diskette. Label the disk "Microsoft
ATAPI Service Pack 4 IDE Driver."

2.Boot from the three setup disks supplied with Windows NT Server.

3.When asked if you would like setup to detect your mass storage devices, press S
so that detection is skipped and you specify a mass storage device.

4.When setup list devices found, which should list , press S again and insert
the Microsoft ATAPI Service Pack 4 IDE Driver disk and press ENTER twice.

5.After setup reads the disk and list the Microsoft ATAPI Service Pack 4 IDE driver,
press ENTER to accept the driver.

6.Setup will now list Microsoft ATAPI Service Pack 4 IDE Driver as an installed
driver. If you have additional drivers for other mass storage devices, press S; if
not, press ENTER to continue through setup.

7.Setup should continue through normally but, it will prompt you to insert the disk
labeled "Microsoft ATAPI Service Pack 4 IDE Driver Support Disk" at the copy
phase after you have chosen or formatted a partition on a hard drive.

try the files in service pack 4( a friend told me) mind you he is not that reliable=:)
