Formatting the Extended Partition
Once you have formatted the primary partition and copied the
remaining MS-DOS files to the hard disk, follow this procedure to
format the extended partition:
1. Insert the working copy of your MS-DOS Startup diskette in
drive A (if it is not there already).
2. At the
A>
prompt, type the following and press Enter:
FORMAT D:/V
3. The screen displays this message and prompt:
WARNING, ALL DATA ON NON-REMOVABLE DISK
DRIVE D: WILL BE LOST!
Proceed with Format (Y/N)?
4. Press Y and Enter to begin formatting the extended partition.
The screen continuously displays the changing head and cylinder
numbers. When the procedure is complete, the screen displays
the following message:
Format complete
Volume label (11 characters, ENTER for none)
5. It is a good idea to enter a name (volume label) for drive D, to
protect it from being accidentally reformatted later. If you want to
name this drive, type up to 11 characters and press Enter. If you
do not want to name it, just press Enter.
The screen displays information about the total disk space
available on drive D. The A > prompt reappears.
6. If you have created additional logical drives on your hard disk,
repeat steps 1 through 5 above for each additional logical drive.
Substitute the appropriate drive letter in the FORMAT
command. For example, to format drive E, type the following and
press Enter:
FORMAT E: /V
