Enhanced IDE Hard Disk Drive - Partitioning and Formatting the Drive


Installation Guide - Partitioning and Formatting the Drive


Partitioning and Formatting Using OS/2

This section contains instructions about partitioning and formatting an additional hard disk drive for the OS/2 operating system.
If you are using OS/2 on the existing drive, use the following procedures to prepare the new drive in order to install OS/2:

  1.  Refer to the Enhanced IDE Hard Disk Drive User's Guide Supplement in order to obtain the OS/2 device drivers necessary  to use the full capacity of the drive.
  2.  Partition and format the new drive for OS/2 using the FAT16 or HPFS file system, or both FAT16 and HPFS, using directions  given in the OS/2 User's Guide.

    NOTE: In larger capacity drives, the OS/2 operating system can partition only up to the first 2.14 GB,  or the first 1024 logical cylinders, of the drive using the FAT file system.

  3.  However, you can partition the entire drive using the HPFS file system.  Use the following equation to determine the extent of the drive capacity that OS/2 and FAT can partition (see the Enhanced  IDE Hard Disk Drive User's Guide Supplement for specifications on the drive's logical sectors and logical heads):

     (default number of cylinders) multiplied by the drive's logical sectors multiplied by the drive's logical heads multiplied by 512 bytes
     Since you cannot partition the entire capacity of the drive using FAT, you must use HPFS to partition the rest of the drive.

  4.  If you choose to make the new drive a boot drive, refer to the OS/2 User's Guide for information on installing OS/2 on the new drive.


Partitioning and Formatting Using Windows NT

  If you are using Windows NT and you are installing a drive larger than 9 GB, you must obtain the Windows NT Service Pack 3 or later so that the system can realize the full capacity of the drive.

To obtain the Windows NT Service Pack 3 or later:

  1.  Go to the Microsoft Web site at www.microsoft.com.
  2.  Select Free Downloads.
  3.  Select Support Drivers, Patches and Service Packs.
  4.  Follow on-screen instructions.


If you added the drive to a computer that has Windows NT on an existing drive, follow the instructions below to partition and format the new hard disk drive using the NTFS (NT File System) convention:
  1.  Turn on the computer.
  2.  Click on Start on the desktop.
  3.  Select Programs, Administrative Tools (Common).
  4.  Click on the Disk Administrator icon.
  5.  Follow the screen prompts to partition and format an additional hard disk drive.


If you installed the drive to a computer that had no existing drive, follow the instructions below to partition and format the new hard disk drive for the Windows NT operating system using NTFS:
  1.  Insert the first Windows NT installation diskette (Setup Disk #1) in the diskette drive or insert the  Windows NT installation CD-ROM in the CD-ROM drive.
  2.  Restart the computer.
  3.  Use instructions given in the Windows NT user's guide to partition and format the drive for Windows NT.


Partitioning and Formatting Using Disk Manager

NOTE: Disk Manager  will add a Dynamic Drive Overlay (DDO) to the drive if it finds a BIOS limitation on the system. DDO is a device driver that Disk Manager  adds to the drive in order to allow the system to access the drive's full capacity. For important information on starting the computer from a diskette or CD-ROM after DDO is added, see below. To install Disk Manager  in order to partition and format the new drive:

  1.  Turn off the computer.
  2.  Insert the DiskGo!  diskette or CD-ROM and restart the computer.
  3.  If Disk Manager  does not boot automatically, type x:dm where x is the drive letter of the diskette or CD-ROM at the DOS  prompt and press Enter.
  4.  Follow the instructions on the screen.
  5.  When the Disk Manager  main menu displays, select View/Print Online Manual and press Enter to view information by  operating system on how to partition the drive and install the operating system.
  6.  Return to the main menu, select Easy Disk Installation, and press Enter to accept the default partitioning.  If you do not want to accept the default drive partitioning, select Advanced Disk Installation to select the own partition sizes.
  7.  Follow the on-screen prompts to complete the drive partitioning process.
  8.  To install an operating system on the new drive, use instructions given in the Disk Manager Online Manual.


  Starting the Computer From a Diskette or CD-ROM After Adding DDO to Drive
When Disk Manager  adds a DDO device driver to the drive in order to correct BIOS problems on the system, it is important that DDO be loaded every time you turn on the computer.
If you ever want to restart the computer from a diskette, you must use the following procedure:
  1.  Remove the diskette, if present, from the diskette drive.
  2.  Start up from the C: drive.
  3.  When the DDO blue banner displays, press the Spacebar.
  4.  Insert the bootable diskette into the floppy drive and press the Spacebar again.
  5.  You can now start the computer from the bootable diskette.


This process assures that the computer system will be able to fully access the entire capacity of the hard drive.
If you ever want to restart the computer from a recovery CD-ROM, you must follow the Disk Manager  on-screen instructions on starting the computer from CD-ROMs after Disk Manager  has added DDO to the drive.
