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]
       qscan -d	DEVICE -t wt [-s #] [-W]

DESCRIPTION
       qscan is	the linux console tool for error correction measuring with op-
       tical devices.  The related plugin allows to use	vendor	specific  com-
       mands  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:

OPTIONS
       -l, --scanbus
		 scan busses for all available optical devices

       -h, --help
		 show help

       -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  com-
       mands
		 [BENQ_DVDROM]	use  Benq  optical reader vendor specific com-
       mands
		 [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 sup-
       ported

       -s #, --speed #
		 set measurement speed to selected value.
		 Use  -S option	before,	if you don't know what speeds are sup-
       ported 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:
		 http://qpxtool.sourceforge.net/glossar.html

		 [rt]		read transfer rate measurement
		 [wt]		write transfer rate on blank media
		 [errc]		errror correction - Cx-scan / PIE,  PIF,  POE,
       POF
		 [ft]		focus and tracking error measurement
		 [jb]		jitter and beta	measurement
		 [ta]		time analyzer measurement

       -w #, --wspeed #
		 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 availabale 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

       please report man page improvements to T.Maguin@web.de
