DVD-R media compatibility and write quality:
In these tests we will be using a Lite-On SHW-1635S drive with firmware YS0N along with K-Probe to measure the disc quality. We will also be using the NEC ND-3540A with firmware 1.03 along with CD-Speed for our read-back tests.

PI errors are quite high throughout the disc but well within specification, and the read-back test is perfect. The result is good.

The cluster of PIF errors is a bit alarming although the read-back test is perfect. The result is ok.

The PIF errors are astonishingly low, and the read-back curve is perfect. An excellent result. Highly recommended!

Once again the cluster of PIF errors near the end of the disc is worrying, and we have a small slowdown in our read-back test.

The PI error levels are quite high throughout the burn and PIF levels are fairly constant throughout the burn, but all well within specifcation. The read-back test is good, another good result.

Again we have a cluster of PIF errors at the end of the disc, this doesn't affect the read-back test which is perfect, another good result.

Again we have the PIF cluster near the end of the disc. Overall the error averages for PI/PIF are good, but we see a slowdown in our read-back test. The result is ok but could be better.

The Lite-On SHW-16H5S has handled the Traxdata DVD-RW media well. A very good result.
To sum it up: Overall, the write quality is good on DVD-R and DVD-RW media, but some improvements would be nice with DVD-R.
Head on to next page and read about DVD+R DL compatibility and write quality...







I have used it only once or twice as it was causing seizure of the computer after the cd had been burnt. I only recently was able to burn CDs without problems when the Nero 6.5 software bundled with the product
that was conflicting with the Roxio software bundled with XP Wizard was removed.
I now find that it will only recognize CDs and will/can-not burn DVDs.
Has any one experienced this problem? Any solution?

Does anyone knows how the Verbatim -R's do on this drive?
