Chapter 5
Moving the Hard Disk
This chapter describes the procedure you use when you plan to move
your computer. Even if you are moving the computer only a short distance,
use option 5, Prepare hard disk for moving, to prevent damage to the hard
disk.
This program moves the read/write heads of each installed hard disk
drive away from the disk surfaces and locks them securely in position. If the
heads are not secure and the computer endures a shock or vibration, the
heads may bump the disk surfaces which could damage the drive. At the
very least, you may lose a considerable amount of data.
To secure the heads, select option 5 from the OPERATION MENU.
You see a screen of information reminding you that the heads will not be
unlocked until you reset the computer or turn the power off and on again.
Next the program moves the heads and disables the keyboard. You can now
turn the computer off and move it to the new location.
You can also secure the heads on your hard disk by executing the
MS-DOS HDSIT command.
