cdvdcontrol -l
cdvdcontrol [-d DEVICE] [OPTION]


pxcontrol gives you access on all features that are supported by your Plextor drive. This tool is what you want, when you use optical devices which were manufactured by Plextor.

-l      scan busses for all available optical devices


cdvdcontrol supports the following features: AutoStrategy, BitSetting, DiagnoseMode, GigaRec, Hide-CDR, MediaLock, PlexEraser, PoweRec, SecuRec, SilentMode, SingleSession, Simulation, SpeedRead and VariRec.

The available features depend on your drive. Take a look at or simply read the glossar on: to see supported features.


can be an IDE, SCSI, SATA, USB or FireWire connected optical drive. Not all SATA controller support all Plextor features.

AutoStrategy (AS) is a Feature to determine a writing strategy for an inserted empty DVD media. Writing strategies are saved in the AutoStrategy DataBase (ASDB). This command needs a specified DEVICE.

--as-mode mode
                select the AutoStrategy mode

        auto    drive selects the strategy from the ASDB or from
                        the firmware. If there is no entry available, a
                        new one is created.
        forced  creates a new ASDB entry, even if there is already
                       one available in the ASDB.
        on              an existing AS from the DB is used. If there is no
                       entry, the strategy from the firmware is used.
        off             only strategy from the firmware is used. If there
                       is no entry available, the default strategy is used.

                view complete ASDB list.

--as-on #
                activate ASDB entry number X (value between 1-10).

--as-off #
                deactivate ASDB entry number X (value between 1-10).

--as-del #
                delete ASDB entry number X (value between 1-10).

                remove all ASDB entries form the ASDB.

--as-create mode
                creates an AS database entry.
                Mode should be combination if [q|f] and [a|r]

                 q            quick AS creating.
                 f            full AS creating. Media is written.
                 a            AS is appended to the list in the ASDB.
                 r            AS entry replaces relying ASDB entry.

--as-load #
                load an ASDB from a file.

--as-save #
                save ASDB into file. For PX-755/PX-760 only!
                PX-755 export maybe buggy.


due to some compatibility problems of some DVD readers, it could make sense to use BitSetting, which sets the Booktype of media to DVD-ROM. This OPTION requiers a specified DEVIVE.

--bitset+r mode
         enable / disable Bitsetting for DVD+R.
                on      defines DVD+R as DVD-ROM media.
                off     keeps DVD+R media as what it is.

--bitset+rdl mode
                enable / disable Bitsetting for DVD+R DL.

                on      define DVD+R DL media as DVD-ROM media.
                off     keeps DVD+R DL media as what it is.


are OPTIONS to detect the drive itself, the current settings and the available features.

-c, --current           show current status of selected DEVICE.

-h, --help              show help.

-l, --scan              search all busses and list detected drives.

-s, --supported show features supported by selected DEVICE.

-v                              show output in verbose mode.


Increase (higher value) or Decrease (lower value) the regular capacity, which can be written on CD media. Ejecting the disc results in flushing the GigaRec settings. Buffer UnderrunProof is disabled while GigaRec is active. The recording speed is limited to 4x or 8x DAO. Use cdrdao or cdrskin for writing media with GigaRec function. Otherwise if you use cdrecord your values are flushed. GigaRec settings need a specified DEVICE.

--gigarec #
               set GigaRec to <state>, which is a value in the
                range of 0.6, 0.7, ..., 1.3, 1.4 or off.


prevents media from being detected by an application as CD-R to defeat the ATIP protection. Hide-CDR settings need a specified DEVICE.

--hcdr [on|off]
                enable / disable Hide-CDR.
              on      enable Hide-CDR. Defeating ATIP protection.
              off     disable Hide-CDR.


can lock your media to prevent an accidently opening. It is always a good idea lock the drive. This OPTION needs a specified DEVICE.
                enable lock modus. Media can not be removed.
                disable lock modus. Media can be removed.


destroys the data on your CD/DVD and makes it unreadable. DEVICE needs to be specified for this command.

--destruct mode
                WARNING: command destroys your media.

                quick   destroy only the lead in of CD/DVD media.
                full            destroy complete CD/DVD media.


Plextor Optimised Writing Error Reduction Control (PoweRec) should detect the optimized writing speed for your media-combination. Higher recording speeds than recommended can result in increased writing errors. PoweRec should prevent you from these errors. DEVICE needs to be specified for this command.

--powerec [on|off]
                enable / disable PoweRec.
                on      enable PoweRec. enabled by default.
                off     disable PoweRec.


Creates a password protected CD-R. To access a password protected CD-R, it is necessary to enter the correct password and to specify the DEVICE

         disable SecuRec.

--securec <passwd>
                enable SecuRec and use a given password. <passwd>
                must have at least four, but not more than ten characters.


Allows some speed finetuning on your drives. Lower values result in more silence. You can specify read speed and tray loading speed. DEVICE must be specified for this command. All settings will be active after reboot. ;-) pxfw /dev/hdX -r

--silent [on|off]
                enable / disable SilentMode

                on      enables SilentMode. This will give you access to
                        further speed and read settings. Default is on.
