       qscan - console tool for	quality	measurement of optical media

       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]

       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

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

       /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


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

       -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
		 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-
		 [BENQ_DVDROM]	use  Benq  optical reader vendor specific com-
		 [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-

       -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

		 [rt]		read transfer rate measurement
		 [wt]		write transfer rate on blank media
		 [errc]		errror correction - Cx-scan / PIE,  PIF,  POE,
		 [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

       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

       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
