CD burning problems

[syhead]

My T42's drive won't burn CD's at speeds faster than 4x.
This problem started a couple of months ago... it used to work just fine.
Anybody here has experienced something like this???

Have you tried updating to the latest firmware ?

It could be the media you are using. Even if you are using the same brand, there may have been a change. For an example: I was using Verbatim CD/R's for some time with good results. I went out and bought a new package of Verbatim CD/R's and was having nothing but trouble. I went on Plextor's site to see which CD/R's were on the manufacturer's approved list. My older Verbatims were listed (by part number), but the newer ones were not. After looking over the package more carefully, I saw that the "good" ones were made in Taiwan, and the "problem" ones were made in India. It turns out they used a different dye in the manufacturing process between these two disks.

FTR, I still use Verbatim disks (made in Taiwan). Verify that you are using quality media.

EDIT: I just thought of one other thing to check. Go to Device Manager, and under IDE ATA/ATAPI controllers > Secondary IDE Channel, verify that the current transfer mode is Ultra DMA 2. The Primary IDE Channel (your hard drive interface) should also be using Ultra DMA.
