This might be a good source for cheap 1.8 drives but remember... this HD was installed in a portable MP3 player. Could have been used by some jogger while (s)he ran marathons

. It would be ideal if you could get a non-DOA guarantee on the hard drive for a "parts or repair" Zen Touch but that might be asking too much. It also looks like Hitachi's DFT program does not support C4K drives. As I'm a bit of an X4 newbie, does anybody know if there's a hard drive diagnostic program for the 1.8" drives?
I have (somewhere in the house) a first-generation Rio Nitrus. It uses a 1" 1.5GB hard drive. I was amazed that it never skipped, nor did it ever experience a head crash, while I went skiing for a couple of seasons with it buried in my suit pocket. It was quickly obsoleted by flash-based players (also made by Rio, along with Apple and the rest) where you don't have to worry about dropping it or subjecting it to G forces beyond it's design limits. Even given that I know the drive's past history, I probably would not want to use it for any critical data storage applications.
