This burns DVD's and CD's great. The only problem I have with it is that I can't copy any CD's or DVD's with it. It always says to insert a disc to copy even though there is already one in the drive. I don't know if it is a problem with the burner or with my OS. Other than that it works perfect. I have burned over 100 DVD's with it with 0 coasters.

The LightScribe image progressively got lighter. Now, finally, my drive can no longer detect recordable blank media. It only sees CD's and DVD's that are already burned. And, Windows 7 now calls it a CD ROM. I plugged in a different burner at the same SATA location, and it burns properly. So, i guess my AD-7241S died after only 6 months and maybe a dozen writes.

I've owned several burners but I have to say this is the best burner I have ever owned!
