AD-7280S with strange reading


All DVD benchmark tests on that drive looks like on first attachment. However, my old drive LG H42N IDE reads all these DVDs with maximal speed, absolutely perfect, like on second attachment.
DVDs burned on 7280 and LG, at 8x and 16x. DVD media from Verbatim with MID MCC03RG20, MCC-004.
Quality scans on 7280 are good. Quality score usual >84.

Does it mean that my 7280 is broken? What do you suggest?

Tests in attachment with the same disc.

That is very odd. Try downloading Discspeed and see if it gives the same results?

It seems like the SATA controller isn’t at the proper settings.
