other reason, then the error will be prompted: "-1022 (JET_errDiskIO) The hardware, device driver, or operating system is returning errors". Why does error -1022 JET_errDiskIO occur? The above error occurs because of a disk input/output (I/O) failure. Whenever the exchange requests a database page and the operating system cannot gain access to that page due to any reason then the error occurs. In such case, Exchange requests a page number that is larger than the number of pages in the database file. The above can also occurs if an incomplete transaction log set is replayed in the database. It can also result to sudden system crashes, system may hang while starting and accessing data. For example: if a transaction is being going on in log 9, it couldn't not be completed as it has exceeded the database size but the new pages reference has been added to log 10 then what would happen? Such incomplete transaction would lead to error -1022. Consider one more case, if a transaction replay is to be started from log n and if the administrator deletes the checkpoint file and log n, then the transaction replay could be forced to start from the log n+1. In such case the above error can occur. In case of exchange 2002, this isn't possible as it prevents such incomplete transaction log replay that can cause damage to the database. It is easily possible in the exchange version 5.5. Below given are some reasons that make the database pages inaccessible by the exchange server and leads to the error -1022 JET_errDiskIO.
