Lost sd-ext on boot, droid x

[JRICKMAN51]

I rooted and installed a rom and upon backup, i noticed during backup that it states that my sd-ext is moved from system. "E" drive is not accessble, want to return this for another before my time is up tommorrow and cannot find a way to reflash an original moto rom to phone due to the above problem, anyone that can assist please, spent days trying to repair whatever i've done as a newbie, help!

Does anyone out there have any ideas on this, i understand if no one knows but please tell me, if i'm in the wrong area please let me know that and i'll go elsewhere, but not one response? Running 2.1.1 with rubix rom, rooted with z4root, anyone? If i've missed a protocal please let me know and i'll oblige, but not even a welcome or sorry your @#$@? I missed my return deadline so now just want to get it back to the way it was, jeff
