Quality Check

Quality Check

KProbe2 is one of the frequently used applications employed for testing readability of written discs. Written by a former employee of LITE-ON (though not in an official capacity), it works naturally on LITE-ON optical drives and helps to give a numerical value to the burn quality of a DVD. This is expressed through the amount of PI (Parity Inner) and PIF (Parity Inner Fail) errors found on the written disc and there is a certain amount of correlation between these values and the write quality of the drive on the various media that we tested. As a rough gauge of the write quality, the average values for PI and PIF for a readable disc should not be more than 280 and 4 respectively.

While the values returned by KProbe 2 are certainly useful for assessing the readability of a written media and the DVD writer that was used to write the disc(s), we must stress again that the average PI and PIF values should be taken as just an indicator; a disc with a less than ideal value may be read without any problems on a drive. What worked on one drive might not necessarily work on another (not to mention that disc quality variation may occur as well).

Despite a few blemishes, the LG GSA-H62N looks like a decent drive that is fast and reliable. Some of the KProbe2 results may not look perfect but most were more than decent. The brand of the media may also be an important factor here. We have some sample KProbe 2 scans below for those who are interested.
