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-DOSInstallation Guide. If you are using another operating system, follow the instructions that came with it.

If you do not prepare the drive correctly, you will not be able to store data on the disk. For example, if you have partitioned the drive and formatted it for MS-DOS (or another operating system) but you do not copy the operating system to the drive, you will not be able to load the operating system from the hard disk when you turn on the computer.

If you are sure the hard disk has been installed properly and you have prepared it for use as described above but you cannot access the drive, review the instructions in your MS-DOS Installation Guide. Make sure you performed each step in the installation process correctly for your configuration.

If you cannot identify the problem, consult your dealer.

Accessing Data on the Drive

If you have been using your hard disk drive successfully for some time and notice a reduction in performance, the data on the disk may have become fragmented. You may want to back up all your data and then use a disk compaction utility to reorganize the files on your disk. Contact your dealer for information.

If you still have trouble with your hard disk, you can back up your data and physically format the disk. Then you’ll need to reinstall MS-DOS and copy your files back onto the disk. See “Hard Disk Format” in Appendix B and your MS-DOS Reference Manual for instructions.

If you cannot access data on your hard disk or you are receiving read/write errors, the disk may have a physical problem. Contact your dealer.
