I just got another 7200S as my last one had some kind of mechanical problem. straight away problems. It does not like writing at 16x or 18x, the disk does actually write at those speeds but they have errors in playback on DVD player, will not analyze past around 30% in DVD Shrink and do not even show up as a DVD in my Liteon drive.
I have tried the following:
Using Verbatim MCC 004 DVD+R media & Sony16D1 DVD-R
About 5 different firmwares, official and not.
Removed the Nvidia IDE & Sata drivers.
Still nothing, bemused by this as my last 7200S was a solid performer and I never had these kinds of problems. Any advice would be appreciated.
