What speed should I use ?
Today after I burn some discs, I use KProbe to scan @8X speed (The disc is written at 4X speed), and I got this results.
IMO, It's not so good.
Then I tried 4X speed cause it's the speed that I burn the disc, and I got this ...
It's not perfect but it's much better than 8X scan.
So, What result should I trust ?
Cause in 8X scan, I got 125 PI and 5 PIF plus 1 error.
But in 4X scan, I got 69 PI and 4 PIF with NO errors (IMO this result is acceptable cause it's really cheap discs -~3.6$ per 12 discs- ) .
P.S. I don't know why there are more Sampling counts in 4X scan than in 8X scan, since it's the same disc (I scan at 8X and follow by 4X W/O taking disc out of the drive) .
Thanks for your help.
