2. If you installed the hard disk in your computer yourself, did you carefully follow all the instructions in Chapter 7? Review the instructions and check all cable connections to make sure you installed it correctly. Also check the jumper settings on your drive to make sure they are set correctly. 3. If you installed a non-Epson hard disk drive, was it physically formatted by the manufacturer? A blank, new hard disk must be physically formatted (or initialized) before you can partition it and install an operating system on it. If your drive was not physically formatted, you must do it yourself. If the drive came with its own format utility, use that program; if not, follow the instructions in Appendix A. Note that a physical format is different from the softwarebased logical formatting commands (such as the MS-DOS SELECT or FORMAT commands). If you're sure your hard disk has had a physical format, see "Preparing the Drive," below, for more information. Preparing the Drive Before you can store data on a new hard disk (which has already been physically formatted), you must prepare it for use as follows: 1. Run the Setup program to define your hard disk as part of the computer's configuration. (See Chapter 2 for instructions.) 2. Partition the drive, format it for MS-DOS, and install MS-DOS. Step-by-step instructions for performing these procedures are provided in your MS-DOS manual. If you are using another operating system, follow the instructions that came with it. Troubleshooting B-21
