I just bought my 2GB Clip a week ago. I was running XP Pro with SP2 and WMP 11. I plugged it in, it showed up, and everything worked great.
My PC at work was running the same OS, but had WMP 10. I couldn’t see the player in My Computer when I plugged it in. I tried the “Hold switch while pressing the center select button” to force it into the MSC USB mode. I could see it on the PC. It showed up as Sansa M350, but I couldn’t see the files I loaded from the other PC running the same OS, but with WMP 11.
I downloaded WMP 11 on the PC that had WMP 10, and that fixed the problem. Now the Clip shows up on both PC’s with the “Sansa Clip 2GB” icon in My Computer and all the files show up. To sum it up, WMP 11 worked, WMP 10 didn’t. The package says you only need WMP 10, but that wasn’t the case for me. I also downloaded some security updates for XP at the same time, but I doubt if that solved the Sansa Clip issue. It was probably the new version of WMP.
So far there are a couple things I like about the Clip when comparing to my m200 players. The faster “fast forward” is great for my talk show podcasts that are usually 40 minutes per file. No more holding down the FF button until my finger hurts to get to the point where I stopped listening. I also like the OLED display. It’s brighter, easier to read, and shows more characters per line. My 47 year old eyes can see it better than the backlit LCD display on the m200’s.
This thing is amazing and so tiny. It reminds me of the old original Star Trek series. Mr. Spock used to stick a small card (but much bigger than an SD card) into the computer and look at data and pictures. It was science fiction in 1968, but available for 60 bucks today at Best Buy.
