NAME

       qscan - console tool for quality measurement of optical media

SYNOPSIS

       qscan [-l] [-h]
       qscan -d DEVICE [-S] [-i] [-m]
       qscan -d DEVICE [-p] [-r] [-w] [-v]
       qscan -d DEVICE [-f] [-s] [-t] [-v]

DESCRIPTION

       qscan  is the linux console tool for error correction measuring with optical devices.  The
       related plugin allows one  to  use  vendor  specific  commands  on  your  optical  device.
       Currently  supported  vendors  are  Asus,  Benq,  Liteon,  NEC,  Pioneer and Plextor.  For
       detailed information look at http://qpxtool.sourceforge.net/supported.html

DEVICE

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

       Linux:
       /dev/hdX: IDE device
       /dev/scdX: Linux 2.4: SATA, SCSI, USB device, or IDE device via ide-scsi emulation
       /dev/srX: Linux 2.6: IDE device via new ATA layer, SCSI or USB device

       OpenBSD/NetBSD:
       /dev/rcdX

       FreeBSD:
       /dev/cd: SCSI device
       /dev/acd: ATA device

       MacOS X:
       /dev/disk:

       win32:
       C:,D:,E:, ... X:,Y:,Z:

       -S, --speeds
                 detect  available  read and write speeds for selected -d DEVICE and the relating
       media

       -i, --info
                 show device info of selected -d DEVICE

       -m, --media
                 show media info of selected -d DEVICE

       -p, --plugins
                 list all available plugins

       -f, --force-plugin PLUGIN [ ASUS | BENQ  |  BENQ_DVDROM  |GENERIC  |LITEON  |NEC  |PIONEER
       |PLEXTOR ]
                 force  usage  of the selected plugin to use the vendor specific commands for the
       slected device.
                 Default behaviour auto detection modus.

                 [ASUS]         use Asus vendor specific commands
                 [BENQ]         use Benq optical writer vendor specific commands
                 [BENQ_DVDROM]  use Benq optical reader vendor specific commands
                 [GENERIC]      use generic mmc commands
                 [LITEON]       use Liteon vendor specific commands
                 [NEC]          use NEC vendor specific commands
                 [PIONEER]      use Pioneer vendor specific commands
                 [PLEXTOR]      use Plextor vendor specific commands

       -r #, --rspeed #
                 set read performance speed to selected value.
                 Use -S option before, if you are unsure which speeds are supported

       -s #, --speed #
                 set measurement speed to selected value.
                 Use -S option before, if you don't  know  what  speeds  are  supported  by  your
       device.
                 Don't use this with -r or -w option.

       -t, --test [rt|wt|errc|ft|jb|ta]
                 select  the q-check you want to be proceeded. Not all tests are supported by all
       devices.
                 For detailed information about the terms read the project page:

                 set write speed to selected value.
                 Use -S option before, if you don't know what write speeds are supported by  your
       device.

       -v, --verbose
                 gives verbose output and debug information

       -W, --write
                 perform real write instead simulation for write transfer rate

EXAMPLES

       qscan -l
                 scan all buses for available optical devices

       qscan -d /dev/sr2 -S
                 Show available speed steps of device /dev/sr2.

       qscan -d /dev/sr2 -t errc -s 5
                 Proceed an error correction scan on device /dev/sr2 with 5x speed.

       qscan -d /dev/sr0 -t wt -s 12
                 Proceed  a  write  performance test in simulation mode on device /dev/sr0 (dummy
       mode) with 12x speed
