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.

Thanks
