qscan(1) qscan 0.7 qscan(1) 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 Gennady ShultZ Kozlov 10.
