Thanks for the advice. I made an ExMerge backup and it threw up some errors like this:
Error copying message with subject ?SUBJECT? (MAPI_W_PARTIAL_COMPLETION) http://support.microsoft.com/?id=328642 So I am not confident that I have made a good ExMerge. I have already run ESEUTIL in /p then /d then ISINTEG last night. When I followed that with a backup the ESE 474 errors came backup and the backup failed. I have just run the Dell Diagnostics on the drives from their boot CD and it came up clean. If the disks (or disk subsystem) is dodgy then why does the mirror not fail and general disk errors occur?

Ian, Make backup with exmerge and run isinteg. If it does not solve the problem run eseutil repair. If this does not solve your problem rehome databases on another disk, format the disk and move databases back. If this does not solve the problem change the disk or rehome the server.

We have an SBS2003 server running on 2x 160GB SATA drives with Windows Software RAID1. The server is about 3 months old. Three partitions: C: system D: data E: empty/backup Exchange DB are on D and logs in default location on C. The server was built using 'Swing Migration' method and the Exchange DB was forklifted from the original server to the new server. Both servers have the same name and AD was migrated. Since the forklift I have been having these events appear: Event Type: Error Event Source: ESE Event Category: Logging/Recovery Event ID: 474 Date: 22/03/2006 Time: 03:49:46 User: N/A Computer: SBS2003 Description: Information Store (5664) First Storage Group: The database page read from the file "D:\Exchsrvr\MDBDATA\pub1.edb" at offset 4296704 (0x0000000000419000) (database page 1048 (0x418)) for 4096 (0x00001000) bytes failed verification due to a page checksum mismatch. The expected checksum was 7987537296697916479 (0x6ed96ed9ffdcfc3f) and the actual checksum was 7944752443766530058 (0x6e416e41271ee00a). 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. Mainly they appear at backup (and the backup fails on Exchange) but also during the day. I am troubleshooting this with MS PSS (Indian Division) and they are not much help. I have run chkdsk /f on Drive D and it comes up clean. I know the event points at hardware being the issue but I am not convinced because it sits on software RAID so I was expecting that if the disks are causing issues for there to be lots of errors / events from RAID? There are none that I can see. In Disk Manager all disks are listed as 'Healthy'. Any ideas? Anyone seen this before?
