Here is the error that pops up once every minute for 4 mintes (4 times) every 3 hours.

Event Type:      Error
Event Source:      ESE
Event Category:      Database Page Cache
Event ID:      474
Date:            3/26/2010
Time:            3:00:26 AM
User:            N/A
Computer:      MAIL
Description:
Information Store (3632) First Storage Group: The database page read from the file "E:\MDBDATA\priv1.edb" at offset 3768365056 (0x00000000e09cb000) (database page 920010 (0xE09CA)) for 4096 (0x00001000) bytes failed verification due to a page checksum mismatch.  The expected checksum was 8317317911392405552 (0x736d0c92c889c830) and the actual checksum was 8317317911392405568 (0x736d0c92c889c840).  The read operation will fail with error -1018 (0xfffffc06).  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.

I found this (http://support.microsoft.com/kb/810411) and this (http://support.microsoft.com/kb/314917/) about the error, and fixing the error. I have checked the HDD's, and not one have any errors. I'm sure there is no overheating as the airflow is perfect, and the temperature in the server room is consistently 65 degrees F.   The firmware is not the most recent, but it's not too old (from 2009). The error simply 'appeared' a week or so ago, and went un-noticed. I use CA Arcserve Backup's folder level backup for Exchange, and it has been completing successfully (no errors at all) for the last few months. Assuming the repair method fails and or damages the database, are my backups useless?

This could be down to a problem with the actual store file.

You may need to run:

ISINTEG –fix -test alltests

The Exchange store will need to be dismounted whilst this runs and users will be unable to gain access to mail.  Always take a backup of your Information store before performing these steps.

Thank you. My only question now is about my backups. Should something happen, can i rely on my backups or will they carry over the same problem(s)?

The backups will have this same problem in them but if for some reason you needed to restore you should run the command I have posted above.
