Today I built a new computer with an Asus Drw-24b1st. It worked great for installing Windows, and I got everything up and running, but I've run into problems trying to get anything else to run off of it. The drive itself is recognized by Windows. I can find it in the device manager, etc. However, anytime I insert media of any type, it spins and the green light comes on like it is supposed to, but I can't pull open the files on Windows. Now, I don't have the latest firmware, but I can't install it off the the DVD because of this problem. I tried getting it off of their website, but when I tried to open one of the files, it said I had the wrong version (32/64 bit) of windows. I'm sure I downloaded Windows 7 64 bit drivers, and I'm sure I'm running windows 7 64 bit. The other file says that it is meant for a DRW-24b1st and I have a DREW-24b1st_a 1.04.
