First, let me point out that you can get a namebrand (NEC, Toshiba, etc.) internal DL/all-format DVD burner for under $80; try Amazon and Newegg. I found this I/O Magic at my local computer store so I bought it. Big mistake. The drive reads DVDs slower than my 3-year-old Iomega (no relation!) and write speed (on DVD-Rs) is nowhere near as advertised. Worse, about half the time it would not recognize my DVD-Rs when first inserted. This is a terrible product. Luckily I returned it for a full refund. Then I found out I could buy a better brand on Newegg for less.This was my first I/O Magic product. I just read online reviews of their hard drive products and looks like this company's products suck big-time. They also sell under the Hi-Val brand, so beware.
