Private Information Store (priv.edb) in MS-Exchange Server gets corrupt because of many reasons. These reasons include sudden server shutdown, malicious virus, anti-virus scanning, log file corruption, and human errors. Once the priv.edb file gets corrupt, you start getting nasty error messages on your screen. Due to these errors, data of the Information store becomes totally inaccessible. In such critical situations backup can be used. In case you don’t have a backup file, you have another option of using third party Exchange recovery software.

Exchange Server Recovery for Corrupt Priv.edb file
Public folder store and Mailbox store are the components of Exchange store. These stores further contain different files in them. In mailbox store, the files are priv.edb, priv.stm and in public folder store, the files are pub.edb and pub.stm. Both these Exchange store components are vulnerable to corruption and their corruption can stop the working of Exchange store service, which can lead to complete inaccessibility of Exchange Server database. To get over the corruption of mailbox store and public folder files, you can run an utility known as 'eseutil/p'. However, in some cases, this utility does not prove helpful to repair damaged database. For such cases, the last solution is a third party Exchange Server recovery tool.
Suppose, you use MS-Exchange database of around 300 GB. The Priv.edb file of your Exchange Server database has got corrupted and you executed the 'eseutil/p' command to resolve the issue. The repairing process by 'eseutil/p' command proceeded successfully, but suddenly stopped with an error message. The error message can be written as below:
“Assertion Failed: dPercentage >=0, file G:\ese97\src\eseutil\edbutil.cxx, line 563.”
Repair process remained incomplete and the data of Microsoft Exchange database became totally inaccessible. After that, the above error message appears every time you try to repair the Exchange database.
Why the error is coming?
The cause, that is responsible for the above stated error message is the corruption of priv.edb file and 'eseutil/p' utility falls short to solve the problem of corruption.
How the error can be solved?
For resolving above error message and to make the data of Exchange Server accessible, You have to follow the below suggestions:
- Use the latest or highest service pack level for Exchange Server 5.5.
- If, the problem still remains the same, you can use an up-to-date backup to restore the database.
If backup is deficient to restore the data or is not available, then you need to go for a third party Exchange Server Recovery product. Such third party Exchange recovery software easily solves the problem of corruption and makes the Exchange Server database accessible. These tools are very simple and even can be used by a person from a non-technical background. You need not have to possess knowledge about Exchange server and once you use the tool, it provides detailed instruction to perform the repair operation.

How to Solve Event 217 and 478 In MS Exchange Server ?
Microsoft Exchange server has been using in small to large sized organization as the server side of e-mail communication systems. In case of Exchange Server crashes, storage groups and exchange databases that stores the data, are the most important component for recovery. When a corruption situation occur in database, You might observe some unexpected behavior. For example, you may not be able to backup it and the corresponding event which indicates the failure is logged in application event log file with the detail description of the cause. However, a damaged or corrupted Exchange database (.edb) file should be restored from the backup. But in the absence of backup, you need an effective Exchange Repair tool to repair and restore the same.
For example, suppose you try to perform an online backup of the ESG (Exchange Storage Group), the operation may fail and you might see the below events logging into application log:
Event 217:
Event Type: Error
Event Source:ESE
Event Category:Logging/Recovery

Event 478:
Event Type: Error
Event Source: ESE
Event Category: Logging/Recovery
Event ID: 478
Date:11/23/2006
Time:10:21:32 PM
User: N/A
Computer: EXCHANGE
Description:

The expected checksum was 2914298788 (0x00000000adb4aba4) and the actual checksum was 4278044063 (0x00000000fefdc59f). The read operation will fail with error -613 (0xfffffd9b). If this condition persists then please restore the database from a previous backup.
Cause
Event 217 in Exchange Server illustrates backup failure and event 478 exihibits the corruption in database. Event 217 might also be occured because of "beyond end of file (EOF)" condition.
Solution
Make sure all the hotfixes and latest updates are available for your Exchange Server. In order to solve the database corruption issue, you need to perform following steps:
1. Restore the Information Store database, using last online backup
2. Attempt to transfer user mailboxes to another store, if you are using Enterprise edition of Exchange Server 2000 or 2003
3. If above solution doesn't works, try to repair the exchange database by executing eseutil /p repair command followed by eseutil /d command to defragment the database. But these command line utility deletes the pages that it encounters as corrupted. For safe MS Exchange repair, you should run EDB Repair tool that uses safe and advanced algorithms to repair and restore damaged Exchange databases.
The interface of these Exchange mail repair utilities are simple and easy to use that provides complete Exchange Server Repair results. You just need to browse or search the corrupt .edb (exchange database) file and the tool scans the damaged file entirely to repair it.

How to Solve Page Checksum Mismatch Error in MS Exchange Server ?
MS Exchange Database files get corrupted or damaged due to many reasons such as abnormal shutdown of Exchange Server, Virus attack, hardware failure and more. When this type of situation occur , the database becomes totally inaccessible and unusable. In case of edb file corruption , you may encounter critical user's data loss situations and at this point, EDB Recovery is the best way to get your data back.
When EDB file gets damaged or corrupted, you would not be able to access your data such as email messages, contacts, notes, tasks, calender entries etc with MS Outlook. This behaviour occurs because MS Outlook will not be able to access your data from the corrupted mailboxes.
Consider a practicle example, when you try to run an online backup of database after corruption, the operation can not be completed and you come across the following error message:
"Database page read failed verification because of a -1018 error" (page checksum mismatch)
You can not access your valuable data from the database after above error and users might face the following problems:
- Cannot send or receive e-mail messages and other items.
- Unable to start MS Outlook.
- Online backups fail to complete with a -1018 checksum error.
- Online defragmentation surfaces a -1018 checksum mismatch error.
To gain access of your data in MS Outlook, you need to identify the root of this issue and perform EDB to PST conversion.
Cause:
The root cause of this error is that faulty hardware parts, firmware and device drivers of hard disk subsystem. The error -1018 indicates checksum mismatch and the specific referenced database page within the Exchange store is corrupt.
Solution:
Try the following steps to resolve the issue:
- Test the system for related hardware issues and replace it
- Upgrade the firmware drivers if needed
- Use the last available online backup to restore the exchange database.
- Perform hard recovery using inbuilt eseutil /p utility or use a third-party EDB PST Converter such as Stellar Phoenix Mailbox Exchange Recovery.
