I have a rooted Vibrant on Tmobile, original ROM. I started having a problem last week of not being able to make a back up of my current ROM. I accidentally ran the option to install Update.zip this morning and now I get "Can Not Mount External SD card error". I ready tried flashing an old ROM but ROM manager tells me it needs an working SD card.

I tried numerous combinations of removing the external card, using the USB to PC cord, USB debugging and even flashed to stock form . No luck. I scrubbed a few online combos and ideas. Im stuck on this one.

Right now its in stock form with the ext card in it (I checked it it looks ok in another PC and on Pupeee Linux). I added ROM Manager, Astro, and Root Explorer. in Astro the SDCARD folder is empty :-(. I know the card has data on it. Is this a partition issue??

Help!

I can get into Recovery mode if that is a start...
