MS Exchange 2007 database corrupt

Hello All....

I have a single node, MS Exchange 2007 server that experienced a hard drive failure (RAID 5) last night.  In the process, Exchange failed.

I have replaced the failed drive twice today.  Each time, the array rebuilds, and exchange starts, but after about 45-60 minutes, the message store crashes:

Event ID: 481 - ESE - An attempt to read from the file <path>\mailbox Database.edb at <ofset information> failed after 0 seconds with system error 1: "Incorrect function".  The read operation will fail with error -1022.  If this error persists then the file may be damaged and may need to be restored from a previous backup.

I then get another event:

Event ID: 1159 - MSExchangeIS - Database error Disk IO error occurred in function JTAB_BASE::EcRetrieveColumnByPtagId wile accessing the database...

I am assuming the database is corrupt.  The failure occurred during last night's backup.  I would prefer to "repair" instead of going to an older backup.  

What is the best method to repair, and how long should it take.  The db size is about 100G.
