recorder suddenly slow

[xlr8]

hello

tonight i have found a problem recording a blu ray disc

using lg ggw-h20l unit on win xp sp3

 

i am using imgburn last version

 

until now, i was able to record blu ray media at 2x, with the 2 buffer indicators at 100% steadily

 

tonight it seems i can not go above 1.3x, and the device buffer indicator fluctuating between 30% and 50%, while the buffer indicator remains at 100%

 

even the rewritable speed for blu ray is slowed, and dvd also are slower, in both reading and writing

 

i have benchmarked every component of my pc (cpu, hard disks and ram) and they are all at same level as usual, so i can not find any bottleneck

 

no hardware changes, no software changes, no virus and so on, every hdd defragmented, same media brand etc

 

this can be a faulty drive? of there can be another cause? someone could suggest me some test or some software for understanding it? it seems it works well, apart the speed of anything it does is half the normal...

 

the sole component i have not checked is the power supply, i do not know any program than could check it, someone knows if it is possible the unit is slower because it is receiving insufficient current or voltage?

 

i do not think it is related strictly to imgburn, but it seems it is the sole program with 2 buffer indicators (at least i know), maybe someone knowing the difference could understand what is happening, what is the cause of device buffer unable to fill and buffer normal at 100% and why all of sudden

 

thank you for attention

from 22 to 00.30 it is 2.5 hours the double as usual, it tries to set 2x write speed but the final is 1.3x

usually the verification is done at 12-15x if i well remember, now it is at not even 2x......

 

(strange file this log it is filled at top)

[xlr8]

solved

 

my apologies

i should have read the faq :-)

 

it seems my drive decided it did not like anymore good transfer mode and gone to pio mode

 

deleted controller and reinstalled, it it ok now

 

thanks for attention

 

 

suggestion: this nice log is very big,

it is not possible to add the transfer mode of the selected drive? imgburn can read it from the hardware?

so next time i fall down in it and i have forgot the cause (me or another person :-))

... this will be immediate to understand

There's no reliable way to check the transfer mode (Windows lies), so the only sure shot way is by removing the controllers and rebooting
