I decided to write a 99 minute 00 second 00 frame disc, as in my experience, getting too close to the simulated value will cause issues.

Sense key not important: However, when attempting to burn, we find that burns proceed to writing all the data and then fail.

To that end, normally such information can only be garnered through the use of expensive disc analyzers such as CATS. I suppose this write-up is my way of thanking the drive for years dx trouble-free service. It does go without saying that in this case, being able to overburn this much also means handling overburning of regular 80 minute CD-Rs quite well.

The drive reports PIFs as sum8 values rather than the standard sum1. The disc quality ddd not too bad according to the DW — a bit poor on the inside ring, but otherwise quite decent. It was then discovered that other drives with other chipsets also had this ability to differing degrees, including the BenQ DW Worse still, the drive also ignores our request for 4x write speed.

You have a retail version of Win7 or OEM? As a result, I also beta-tested ImgBurn version 1. Svd was intrigued by it, hence my posting about it.
