High-level formatting

High-level formatting verifies the information written by the low- level format and creates file allocation tables used to catalog and access files.

Caution. Make sure that you know the correct drive letter for the partition you wish to format. Formatting a drive that contains data may destroy the data on that drive.

1.Run the FORMAT program. Insert a DOS program diskette containing the FORMAT program into your diskette drive. At the DOS prompt, type format, followed by the drive letter for the first drive partition you want to format (for example, format C:). Then, press ENTER. Repeat this procedure to format each of the new drive partitions you have created. Consult your DOS manual for FORMAT command options.

Note. If you are formatting the drive partition that will be used to boot your computer (the “C” drive), copy the DOS system files to this drive. To do this, type /s after the format command (for example, format C: /s)

2.Verify the drive capacity. After high-level formatting a drive, you can verify the usable drive capacity by running the DOS CHKDSK utility program.
