I guess I should've picked a better title for my thread about setting up EWF on XP Pro since it doesn't seem a lot of people know what I'm talking about...

Anyways, like knubile said: we've setup XP Pro to be readonly. Regardless of whether you use it with a CF card or not I think this is a much better solution. You can have a readonly volume with the OS on it and another drive (I'll be using a 2.5" USB drive) for your datafiles (MP3's, videos, etc.). What I'm thinking of doing is, like Drivesoft says, have the system always go into standby. Doesn't the Opus automagically shutoff when it sees the voltage drop too low? If not just setup a scheduled task to shut the system off after X amount of time. This wouldn't be a problem since you can just shut the machine off and Windows won't complain or try to run chkdsk on reboot since the volume can't be corrupted (it's not doing any writes thanks to EWF). Also, you can make what MSFT calls a "Hibernate Once Resume Many" system. Instructions are in the EWF thread. This allows you to come out of hibernation every boot even if you just pulled the plug on your system or didn't hibernate explicitly. There are a lot of cool possibilities using EWF and once I get my damn CF card I'll be able to test it out. MSFT has some tips for XPembedded developers on deploying to a CF card. They suggest using FAT if you don't need NTFS since that minimizes writes even more. They also talk about how to install XPe on a CF card with the removable flag. Anyways, we'll see how this goes.
