I've done a fair amount of work with the Disk On Chip 2000, and my company even has them for sale if you need more. We also have our own little toolbox for formatting and partitioning the drives, however its all setup to use our controllers so i'm not sure how much use it is to you. You can take a look though: www.jkmicro.com http://www.jkmicro.com/downloads/zip/DiskOnChipToolbox.zip It could just be that your DOC isn't formatted and thus not showing up, and i've also seen failed DOC that won't respond at all. You might want to make sure you start with a fresh one. I wouldn't be surprised if the old WinCE firmware on there used some wacky partitioning to obscure their executables. If they are FAT formatted though you could plug them into one of our boards and at least get the executables off.
