After installing gparted and mgmt-tools from Penguinbait and using them to clone the flash to internal SD, the N800 can no longer read any SD card. It reports that every one is corrupt even though they are accessible in other devices and on my Mac. It even refuses to format or repair them. I can boot from either from flash or SD but while in Maemo I can not access any memory card with any file manager.

Do I need to reflash?
