i received the drive yesterday. and i tried to enable the perfomance mode in this drive. no pioneer drive utility recognized this drive. but i found a way with linux and a third party program, to enable the performance mode.
you need debian or ubuntu etc and install this program with:
apt-get install qpxtool
now plugin the drive and check with:
cdvdcontrol -l
u will get a output like this:
** CDVD Control v1.4 (c) 2005-2009 Gennady "ShultZ" Kozlov
** scanning IDE/SATA/SCSI buses...
D: [00] '/dev/sr0': 'PIONEER ' 'BD-RW BDR-UD04' '1.14'
** Scan complete: 1 device(s) found
if the drive ist recognized, it will be normaly shown under /dev/sr0
now u can enable the performance mode with:
cdvdcontrol -d /dev/sr0 --pio-limit off --pio-quiet perf
with:
cdvdcontrol -d /dev/sr0 -c
u can check if the performancemode is activated. it will be shown like this:
** CDVD Control v1.4 (c) 2005-2009 Gennady "ShultZ" Kozlov
Device : /dev/sr0
Vendor : 'PIONEER '
Model : 'BD-RW BDR-UD04'
F/W : '1.14'
CDVD Control flags : DEVICE PIOLIMIT PIOQUIET
QuietMode setting : Performance
Speed Limit : ON
normaly, the speedlimit, which is for cd/dvd speed, must be set to off, but it always stay at on.
i testet it with opti drive control. before this, i get constantly only 2x (8mb/s) it starts with 2xand goes till the end with 2x. now checking the same original bd disc also with opti drive control, it starts with 2.61x and it gets constantly up and up, and dont stay at 2xall the time like before. now after ca. 20min 50% of the disc read is reached and the readspeed was @6.18 max, and now after 50% it gets slowly down again. definetly a worth enabling the performance mode, if u only rip discs as fast as possible.
if someone has another, a better way, i would like to it. but for now, its ok like it is
