NAME    [Toc]    [Back]

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

SYNOPSIS    [Toc]    [Back]

     None.

DESCRIPTION    [Toc]    [Back]

     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 doesn't include a worm driver, and isn't
     likely to include one in the future.  Future in-kernel support for CDR/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 collection.

     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.

AUTHORS    [Toc]    [Back]

     The first skeleton for a worm driver has been written by Peter Dufault in
     May, 1995.  The driver has then been improved and made actually usable at
     all by Jorg Wunsch in January, 1996.

HISTORY    [Toc]    [Back]

     The worm driver appeared in FreeBSD 2.1, and disappeared in FreeBSD 3.0
     with the advent of the CAM SCSI layer.
