EDB Corruption When Defragmentation Fails

Microsoft Exchange Server runs a defragmentation process to rearrange the mailbox store and public folders and stored data more competently, eradicating unused storage space.
You could use Eseutil utility for defragmenting the Exchange Server database. It examines the basic structure of the database and rearrange them. It is required for better performance of the database.
Sometimes when you defragment the database, the process fails half-way though. After the process gets halted, you get a temporary file of Priv1.edb. When you rename this file, it gets disappeared. In such situations, the Mailbox store gets corrupted and you can not mount it. In this case, when you use the Eseutil /MS (to dump the space usage), the operation gets terminated with the following error message:
“Error -2211 (JET_errSLVHeaderCorrupted, SLV file header contains invalid
information)”
After getting this corruption error message, when you use Eseutil /P to repair the database, you will get the further error message stating:
“Checking database integrity. Operation terminated with error -1206 (JET_errDatabaseCorrupted, Non database file or corrupted db) after 1.912 seconds.”
This behavior results into the inaccessible Exchange Server database. You can not retrieve even a single bit of data from the database and you may fall in the grave situations of data loss.

Cause

As stated in the above error message, this problem takes place due to damaged Exchange Server database. The database corruption could be the possible result of unexpected system shutdown, virus attack, oversized EDB file and so forth.
It does not matter what the reason of data loss is. The only thing which matter is how to retrieve your precious data? The answer of this question is Exchange Server recovery.
Exchange recovery is the process of repairing the damaged database with the help of EDB recovery software and restore it. EDB recovery software are easy to use tools, which help you in all cases of EDB corruption and can recover all of the EDB objects.
Stellar Phoenix Mailbox Exchange Recovery is the most advanced Exchange Server repair software. It supports EDB repair from Exchange Server 5.5, 2000, and 2003. It systematically scans the entire database and ultimately gives you fruitful results of Exchange Server recovery.
