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 optical 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 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:
		 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
