Hi there!! I'm now in my spending months where I buy all kinds of stuff till I run out of money again I was tired of my bulky conventional cd player so I bought a creative zen: http://www.nomadworld.com/products/Jukebox_ZenXtra/ It's got 30 gigs of space and it's sound is very good. The thing is that, as you may know, It saves the mp3 files in a hdd disk, not in a memory device. I'm now going to the gym and I run about 30 minutes every day. Thats a lot of movement and I'm afraid that the HDD will get damaged or it will eventually fail. Should I turn of the Zen player while I'm running?
