After crash in my server sbs2008 sp2 i get the event messege:
MSExchangeIS (2148) First Storage Group: The database page read from the file "E:\Exchange Server\Mailbox\First Storage Group\Mailbox Database.edb" at offset 10441555968 (0x000000026e5d8000) (database page 1274603 (0x1372EB)) for 8192 (0x00002000) bytes failed verification because it contains no page data. The read operation will fail with error -1019 (0xfffffc05). If this condition persists then please restore the database from a previous backup. This problem is likely due to faulty hardware. Please contact your hardware vendor for further assistance diagnosing the problem.
