Exchange 2007 database won't mount due to E00 corruption

I rebooted my Exchange 2007 server due to some issues I was having and my main database will not mount now. I should note that this database is ridiculously large (420GB) which of course contributed to some of my issues in the first place.

The key error in the event log seems to be - "MSExchangeIS (1984) First Storage Group: Corruption was detected during soft recovery in logfile C:\Program Files\Microsoft\Exchange Server\Mailbox\First Storage Group\E00.log. The failing checksum record is located at position END. Data not matching the log-file fill pattern first appeared in sector 2047 (0x000007FF). This logfile has been damaged and is unusable. "

I tried deleting the .chk file and it replayed all the logs, but gave the same error. eseutil /ml on e00.log fails as well. I think I have all the necessary files, but e00 is just corrupt.

I have a backup from 2 days ago. I'm currently copying this storage group folder to the server (i hope that's all I'd need) in case I need to go this route though at 420 gigs, it's going to take awhile...

I'm really hoping to get things back up and running in the next few hours before the start of the work day. Thanks.
