worm(4)

NAME

worm - write-once (CD-R) disk driver

SYNOPSIS

None.

DESCRIPTION

The worm driver was provided under FreeBSD releases prior to

FreeBSD 3.0.

The FreeBSD SCSI layer was replaced for FreeBSD 3.0 by a

CAM-compliant
SCSI layer. The new SCSI layer does not include a worm

driver, and is
not likely to include one in the future. Future in-kernel

support for
CD-R/CD-RW/DVD drives will likely be implemented through the

cd(4)
driver. Users who wish to write CDs on a WORM, CD-R, or CD

RW drive
should use cdrtools, which is in the FreeBSD ports collec

tion.

The cd(4) driver provides read-only access to CD, CD-R, and

CD-RW drives,
as well as WORM drives that support the CDROM command set.

Therefore,
users wishing to mount CDs in a WORM drive should use the

cd(4) driver
instead.

HISTORY

The worm driver appeared in FreeBSD 2.1, and disappeared in

FreeBSD 3.0
with the advent of the CAM SCSI layer.

AUTHORS

The first skeleton for a worm driver has been written by Pe

ter Dufault in
May, 1995. The driver has then been improved and made actu

ally usable at
all by Jorg Wunsch in January, 1996.
