Hi All
We have a SBS2003 with exchage 2003 SP1 we comeup to the 18gig limit and would like to install SP2
But after a onlime backup & copy /backup of the exchage dir to an other disk. we get the following error
each time we try to run the off LINE DEFRAG :=

CD  exchsrvr\MDBDATA\
E:\exchsrvr\bin\eseutil /d /p priv1.edb /tp:\tempemaildefrag\temppriv.edb
eseutil THEN EXITS WITH :-
 error -1018 (JET_errReadVerifyFailure, Checksum error on a database page)
event logs show:-

event ID=470

eseutil (4572) Database E:\Exchsrvr\MDBDATA\priv1.edb is partially attached. Attachment stage: 4. Error: -1018.

event ID 474;

eseutil (4572) The database page read from the file "E:\Exchsrvr\MDBDATA\priv1.edb" at offset 295747584 (0x0000000011a0c000) for 4096 (0x00001000) bytes failed verification due to a page checksum mismatch.  The expected checksum was 3547725309 (0xd375fdfd) and the actual checksum was 878525284 (0x345d3b64).  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.


note - exchange was working but slow

Action taken:-
rebooted the server
read lots of web pages & EE questions !

Any one through ?

Does Powershell have you tied up in knots?

Event ID 474 refers to one (or more) corrupt pages in
the database. Eseutil will not attempt to fix those pages - it will simply
discard them. This means that you may lose data. Of course, you could get
lucky and have the corrupt page not contain anything important, but then
again...

Also, you shouldn't have to run repair on ALL databases, just the one that
is showing up in the error (unless of course you are seeing the same event
for both databases). When you look at the events, they should tell you
which database online maintenance is currently running on (when it starts,
stops, etc.).

Finally, once you have run eseutil in repair mode, you then need to run
eseutil in defragment mode (/d) as a repaired database should not be used in
production

i would do a complete backup of the exchange server and then use eseutil to repair the database using just the p switch or leave it as it is and maybe build a new exchange server and migrate to a new database
