Status: offline Dear all,I found I was unable to do a full backup on my Exchange server 2003. The error I've got in my CA Brightstor ArcServe V9 is "E8602 Failed to read from database --EC= Backup Agent Error --(69) Read/Write error in named pipes". So I use eseutil.exe /k to check the database of my Exchange server, I got this result:File: d:\program files\exchsrvr\mdbdata\board.edb Checksum Status eseutil /k (% complete) 0 10 20 30 40 50 60 70 80 90 100 |----|----|----|----|----|----|----|----|----|----| ...............................ERROR: page 956171 checksum failed ( 0x779e779ecac5729d / 0x77c277c2c187091b )......ERROR: page 1130500 checksum failed ( 0x64786478ce5a4091 / 0x64786478ce5a4081 )ERROR: page 1130516 checksum failed ( 0x79aa0655e4ab0b31 / 0x79aa0655e4ab0b21 )..............1534146 pages seen3 bad checksums1286 uninitialized pages0 wrong page numbers0xee43d02 highest dbtime (pgno 0xd4)95885 reads performed5992 MB read55 seconds taken108 MB/second56732585 milliseconds used591 milliseconds per read37281 milliseconds for the slowest read79 milliseconds for the fastest readFile: d:\program files\exchsrvr\mdbdata\board.STM Checksum Status (% complete) 0 10 20 30 40 50 60 70 80 90 100 |----|----|----|----|----|----|----|----|----|----| ...................................................543744 pages seen0 bad checksums77269 uninitialized pagesOperation terminated with error -1206 (JET_errDatabaseCorrupted, Non database file or corrupted db) after 105.31 seconds.Could anybody tell me how to fix this "bad checksums" error?

Also, it explains the difference between all these errors and what kind of problem http://recover-email.blogspot.com/2015/05/fix-exchange-jet-error-1018.html in database results in this kind of these errors. Detailed Information » In Microsoft Exchange Server, there is built-in functionality to identify EDB file-level damage to the checksum error pages. Amongst the various symptoms that inform about this sort of damage to the DB, three of the very famous errors are: -1018 JET_errReadVerifyFailure -1019 JET_errPageNotInitialized -1022 JET_errDiskIO Nevertheless, damage to database of Exchange Server can take place at different levels. Possibility is the pages in the EDB file are corrupt, or the B-tree structure checksum error on is dis-ordered, or the index of EDB file is damaged. Depending upon the scenario, DB corruption is classified as: Page level Database level Application level Using Eseutil.exe /K switch, page-level integrity of database can be checked out and fixed. In order to detect database and application level inconsistency, Isinteg utility is available for help free of cost by Microsoft. Page level damage that generally occurs due to issues with Operating System, drivers, hardware is categorized as Physical Corruption. On the other hand, Database and Application Level damage caused due to problem in B-tree structure, table or index of EDB file comes under Logical Corruption. Exchange Server error messages discussed in this article are caused due to page-corruption of EDB file. Amongst all, -1018 is the mostly-encountered error and thus there is more discussion done in this section on its cause and recovering from it. The other two errors: -1019 and -1022 are generally caused because of bug in the application (Excha
Jet Error 1018 » Fix Exchange Jet Error 1018 » How to Fix Exchange Jet Error 1018 Easily In this post, we will discuss about Exchange Error 1018 which usually occurs when the database gets corrupted on the page-level. The Exchange Server has a built-in facility which helps in determining and fixing any damages which that take place in the database at file-system level. If the EDB file is corrupt at page level, the exchange database is commonly hit by the 1018 JET_errReadVerifyFailure error (probably during online backup creation). Depending on what went wrong, the Exchange ServerDatabase may get corrupted at various different levels. For instance, at times the index is dis-ordered or the EDB file is corrupt. Based on the type of failure, DB corruption of Exchange Server can be classified as Logical Corruption and Physical Corruption. Resolve Exchange 2007 Error 1018 from Physical Corruption Meanwhile, to verify the file-system damage to database, one can use Eseutil. All you need to do is to apply the/mh switch. It will automatically scan the header of the DB for the point where checksum value stability determines integrity of the database. Fix Exchange Errors & Restore Mailboxes withMicrosoft Exchange Recovery Software How to Verify Exchange Database Page Corruption? For a layman user, Exchange Database looks like yet another system-file saved with .edb file extension. However, at the logical level, an EDB file consists of 4KB pages (or even multiples 4KB, depending on the OS and the version of Exchange in use). In order to keep the I/O operations minimal, these pages are organized in a B-tree structure. Some of these pages might contain data while others may have pointers which link one page to another. Having such a structure ensures that once a query is raised, traversal is faster and you obtain quick results. Further, indexes and tables manage data using a separate B-tree structure, which is called B+ tree. The header occupies the first two pages of Exchange database EDB file. This means the
