gets corrupted on the page-level. The Exchange Server has a built-in facility which helps in determining and fixing operation terminated with error -1811 (jet_errfilenotfound, file not found) 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 eseutil jet 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.

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
page-level corruption of database. In Exchange Server, there is built–in facility that could help to detect and fix damage done to the database file at file–system (page) level. The most common error that a DBA administrator could

probably while online backup creation). Database of Exchange Server has possibility to get corrupted at different levels, depending upon what wrong has happened jet error 1811 to it. For example: if the page of EDB file is corrupt or the index of database has been dis-ordered. According to the scenario, DB corruption of Exchange Server is categorized as Physical corruption and Logical corruption. http://recover-email.blogspot.com/2015/05/fix-exchange-jet-error-1018.html Meanwhile, if file-system level damage to database has to be verified, Eseutil can be used. Using the /mh switch against the DB, its header can be checked out where checksum value stability determines integrity of the database. How to Verify Exchange Database Page Corruption? At user's end, Exchange database is like any other system-file saved with .edb file extension. Meanwhile, at a logical level, an EDB file is made up of 4KB pages (depending upon http://www.edb.2pst.net/blog/exchange-error-1018.html versions of Exchange and Windows OS, it can be multiple of 4 KB too). These pages are organized in B–Tree structure that ensures minimum I/O operations. These pages in EDB file can have data stored in or it may have pointers that link a page to another page. Such database structure ascertains that while any query is made, faster traversal to the tree is done for quick results. Further, tables, indexes have separate B-tree structure to manage data which is known as B+ Tree. The first two pages of Exchange database EDB file are reserved for its Header which means that first logical page of database is the third physical page. To calculate Logical page number of EDB file, the formula is: However, the checksum value of database is equally important to its page numbers. When a transaction is being written to the disk, a mathematical calculation for the page is done which is called Checksum. This value is held by the header of EDB file and whenever the database is read for any general task or while online backup creation, the checksum value is calculated again. This re–calculated value is then matched with the value stored in the header. If these values do not match, it indicates that the page is corrupt.
