Miserably, I met with the HDD1 error problem.
I installed one GPS application and was testing one GPS application, and I wanted to suspend the CF GPS card before I suspend my C3000. So I clicked the console icon, but it didn't appear. And a few seconds later, the GUI quit and froze there. I can do nothing but take out the battery to do a reboot.

Then the HDD LED is green, and the screen tells "HDD1 error". I don't know what happened to my C3000. How can this happen? Have I done something wrong to it? Or is there something wrong with the microdrive? How to avoid such kind of problem?

I just followed Zaurus_Support's thread, and did the menu 3 and 1 option, then it works again, but I lost all my applications and datas on my microdrive. It has plenty of software and some of my working compilation for dosbox/bochs/libSDL stuff.

Too miserable.

you can disable the hdd3 erase dealie when you do a factory restore.

Would you like to give me more information on how to disable the HDD3 erase?
Thus avoid such kind of consequences.

check out meanie's site. He has the rc.rofilesys lines you need to change etc.
