Note Formatting destroys any previously existing data on a disk
and ignores drive assignments
created with the assign command.
You should
not format disks on drives used in the assign, join, or
subst commands, and you cannot format disks over a network.
Format returns the following exit codes:
o
3
4
5
Successful completion
Terminated by user ( CONTROL·C)
Fatal error (any error other than 0, 3, or 5)
N response to hard disk prompt, "Proceed with format
(YIN)?" .
You can check these exit codes by using the errorlevel condition I
with the if batch processing command. L
!Examples:
To format a floppy disk in drive A and put the operating system
on it, type the following:
forma t a: Is
And to format :a floppy disk in drive A for use with data, type the
following:
format a: Iv
The Iv switch causes format to prompt you for a volume label.
You should type a label since it will help you identify
the data
that
the disk contains.
