Gregory's Server@fraggle @shawnhooper The data corruption seemed to be related to write caching by SmartDrv, where it could sometimes wait a few seconds at the doors prompt before writing. DoubleSpace just made it more severe, because the corruption could hit the filesystem.
Power failures could also cause problems, but didn't experience any that did corruption.
@arem @shawnhooper apparently the "solution" was to flush write buffers whenever an application exited. So as long as you waited until you saw the C:\> prompt before powering off, you'd be safe. Kind of a hack but I can't imagine a better solution considering the limitations of the system and what people expected of it
