NAME

fdformat − format diskettes for use under SunOS

SYNOPSIS

/usr/bin/fdformat [ -L ] [ -2 ]

AVAILABILITY

Sun386i systems only. 

DESCRIPTION

fdformat is a program for formatting diskettes to use with the SunOS operating system.  All new blank diskettes must be formatted before use.  fdformat formats and verifies each track on the diskette, and terminates if it finds any bad sectors.  fdformat destroys all existing data on the diskette. 

By default, fdformat formats a 1.44 megabyte 3.5-inch high density diskette.  Use the -L option to format 720 kilobyte 3.5-inch diskettes.  Use the -2 option to format diskettes in the optional external 5.25-inch floppy drive. 

To format a diskette for use under MS-DOS, use the MS-DOS FORMAT command in a DOS window on the Sun386i system. 

OPTIONS

-L Format a low density diskette. 

-2 Format a diskette in the optional external 5.25-inch floppy drive.

BUGS

The SunOS system currently doesn’t support bad sector mapping on diskettes.  Therefore, a diskette is unusable if fdformat finds an error (bad sector).
