slower than specified

[xlr8]

hi

 

it is some time i have the blu ray recorder lg ggw h20l

 

i have the following problem, this is happening only recently

 

sometimes imgburn refuses to go faster than 1x to record 50 gb verbatim disks

 

it is not always, only sometimes, and obviously i always specify write at 2x speed, so it is not the pio mode problem

 

the disks are written ok, as far as i have checked but it took too much time to write them and after verify them

 

the log reports the correct media and the correct speeds to write them to, and it writes "....recording speed at 2x..." but it is not true:

If the buffer are both full (and rock solid), there probably isn't anything I can do about it anyway.

 

ImgBurn will always send data to the drive as quickly as it'll accept it - so if it's burning at 1x, that's all your drive wants to do.

thx for your reply

 

so what could be the cause?

 

bad blu ray disk? (how do i check it?)

 

damaged sata cable? (maybe tomorrow morning i go buy another)

 

recorder towards physical failure?

 

and what is that 40 mb buffer reported in the log, and how (if) can i increase it?

 

 

 

checked hard disks with sandra and they are ok, no virus and so on...

 

 

thx again
