Today I tried a Ritek G04 4X DVD-R and it burned smoothly at 4X till the end. But the disk cannot be recognized by the burner, I tried another DVD-ROM(pioneer) and DVD player, both said the disk is blank.
Then I tried SONIC 8X DVD+R to burn about 4G data.It ran okay first but when it came to 97%, I got the “focus or tracking error”. I got the same error before when I burned a Smartbuy(prodisc) 4X DVD+RW at about 34%. But the same DVD+RW can be burned very well at 2X.
So far, the only disc that I burned without any problem is the Maxell DVD-RAM.
I am kinda frustrated and gonna exchange this drive tomorrow.
Any one got any idea??
Thanks a lot.
