Corrupted RAW files on CF Card

I just shot a wedding and just about half the images are corrupted on the card... Brand new 30D with a LEXAR 80x 1GB

Do I need a voltage regulator for external flash devices?

Have I Fried my camera? or Just Damaged some files because of the flash output?

I'm not sure what to do... someone please help

Need more info. What flash device??? how is it connected??? What makes you think the CF is corrupted??? Can you see image in the cameras LCD???

From camera I have no luck connecting with the computer..
From PCMCI I can view for a while and then CRASH... It stops responding and is no longer recognized in MY Computer...

The Camera's LCD Can view the few I was able to download... And then shows me a screen with a big question mark and the text "Corrupted files"

There image recovery software out there that you can try they might b able to reassemble some of them for you.

I'm Trying photorescue 2.1 Demo with no luck.

The PCMCIA Drive keeps crashing the computer and software.

Anyone out there know what to do?

You might have better results with a USB reader; I don't particularly think it'll make much difference, but for $10-$15 it's worth a try. Also try using file recovery software on the card, rather than opening it in Explorer. But Lexar cards have been busy earning the company a bad reputation around here in the past couple of years.
