2.Have you inserted the right type of diskette? The diskette type is normally shown on the manufacturer’s label. In the top drive, which has a storage capacity of 360KB, use 51/4-inch, double-sided, doubledensity, 48 TPI, soft-sectored diskettes. If you have a second 360KB floppy disk drive, use the same type of diskettes in this drive.

If you have a second floppy disk drive that has a storage capacity of 1.2MB, use 5?&inch, double-sided, high-density, 96 TPI, soft- sectored diskettes in this drive.

The two diskette types are not interchangeable between the two types of drives. You cannot read or write to a high-density diskette in a 360KB drive. You can read a double-density diskette in a 1.2MB drive, but do not write to it unless you format it in a 1.2MB drive as a 360KB (or 320KB) diskette first. See “Choosing Diskettes for the Equity II” and “Drive and diskette incompatibilities” in Chapter 3.

3.Is the diskette write-protected? There may be a write-protect tab over the notch on the side of the diskette. Before you remove the tab, check the directory to see what files the diskette contains-it may contain information you do not want to change or lose. (Your oper- ating system manual tells you what command displays a directory.) Although you should normally write-protect all software diskettes, some programs store temporary files on the diskette. These pro- grams do not work if you write-protect the diskette.

4.Have you told your system what types of floppy disk drives it has? First see “Setting the DIP Switches” in Chapter 1 to make sure you set switches l-l,l-7,and l-8correctly. Then use the MS-DOS SETUP program to check that your drive type settings match your system configuration. See the MS-DOS manual for instructions.

Hard Disk Problems

If you have problems with your hard disk when you first start to use it, check to see if it is set up properly. See “Using a Hard Disk Drive” in Chapter 3 and refer to your MS-DOS manual.

If you cannot access data stored on your hard disk, you may have accidentally repartitioned or reformatted part or all of the hard disk. If you have not done so and your hard disk does not function properly, have an authorized Epson service center check your hard disk. Never open the air-tight container that encloses the recording disk.
