Solution:

If you are using Windows NT 4.0 Workstation, Server, or Terminal Server,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. Please follow these instructions to solved that question: 1. Download the updated Atapi.sys from Microsoft's FTP server 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.
