Root Cant flash new roms after swapping SD cards

[timcity]

I got a Droid 2 recently and decided to put the 16 gb card from my O.G. Droid but before so I wiped everything from it, minus my pics and vids. My Droid 1 is rooted and I wanted to go back to it but now when I try to flash a rom it doesnt work and it looks like a bunch of stuff is missing from the SD card or whatever it needs for clockwork to do its magic.

So the question is what do I need to do to get back to where I can flash roms willy nilly like before? Do I need to go to stock then re-root or is there a more simple way?

Thanks in advance.

reformat the sd card. Flash recovery via rom manager. You could back up anything important to the computer first and restore it later. like music,movies,pics, etc..
