Never attempt to open the hard disk unit. The disk itself is enclosed in an air-tight container to protect it from dust.

If you plan to move the hard disk unit, the read/write head must be moved away from the disk recording area. The MS-DOS program to protect the read/write head is HDSIT. Refer to your Diagnostics or MS-DOS manual for details.

Inserting and removing diskettes

To insert a diskette into a disk drive, hold it with the label face up and the write-protect notch to the left (so that the read/write slot is away from you). Then slide it into the disk drive as shown in Figure 2-3. Be careful not to force the diskette into the slot. When it is all the way in, push in the disk lock/release button to secure the diskette in the drive. This enables the read/write heads to access the diskette.

Figure 2-3.Inserting diskettes

To remove the diskette, press the button again. As you release it, the labelled edge of the diskette pops out. Carefully pull out the diskette, place it in its protective envelope and store it properly,
