To replace a hard drive, first disconnect power from the system. Remove the controller, data, and power cables from the unit. Next, remove the mounting hardware and remove the drive. Install the new drive and attach the power and controller cables. Check the drive documentation and determine the drive type. The drive type finds certain disk parameters, such as number of heads, sectors, and the total megabyte storage capacity. This information is provided with a new drive, or can be obtained from reference books.
Once you have determined the drive type, power up the system and will CMOS setup program. Enter the new drive type number when prompted. If the drive type is not available, many bios manufacturers offer a type XLVII, user-defined option. The user-defined type allows you to manually enter each drive parameter as requested, thus creating a new drive type.
The next step is preparing the disk for use. When you boot up the first time after a new drive installation, you must use a floppy disk at with DOS on it. Place the disk into drive A, and power up the computer. If you have an MFM or RLL drive, perform a low-level format, partition, and high level format. If installing an IDE drive, partition and high level format only. After formatting, install DOS and other software is needed. Run a disk diagnostic program to verify everything is okay. If the computer is booted with DOS 5.0, it will automatically prompt you to partition and format the hard disk.
