exchange 2000 infomation store keeps dis-mounting

Hi
I have an exchange 2000 server, the problem is the the mailbox store keeps dismounting i can remount it when it drops and all will be fine but within 20 - 30 minutes the infomation store will dismount again. there are a few errors in the application log i think the one which pertains to this issue is:

Database error Disk IO error occurred in function JTAB_BASE::EcCreateIndex while accessing the database "First Storage Group\Mailbox Store (EXCHANGE)".
I have checked the disk space and everything seems to be ok

Any help will be much appreciated

Thanks in advance

I would never do anything like that remotely. This is CRITICAL, you NEED to be on location (or send someone there)

is this exchange standard or enterprise edition?
if it is standard then you can check the database size to see if it has hit the 16 GB limit

Hi,

I would begin by checking the hardware for possible physical disk failures.

You need to run chkdsk or similar to check for disk errors

hi it looks like it is a disk error, will it work if i copy the edb file to a different disk?

consultkhanCommented:
Yes you can move databases to a different physical disk .
you can do it from the database tab in the store properties.

ok i tried that but the databases wont copy as the disk is damaged i keep getting crc errors and copying fails.

If i run a disk check on the volume is there a chance of the infomation store becoming corrupt?

Is there any way i can get this infomation off that disk before running a disk check as copying wont work.

any ideas?

chkdsk without any options will only check the disk, not write to it. Do you have a backup of the database? In that case restore it to the same disk first, writing may remove the crc. If that works, then move the database to a new disk and scratch the failing one

last successful backup was a week ago so im trying to leave that as the last resort,
another option, this disk is a is being mirrored how do i scratch this disk and start using the mirrored partition?

will this work??

peakpeakCommented:
If it's mirrored you can shut down the server (safest) and physically remove the offending disk(s) then start up again. If you're lucky you can them move the database away form the mirrored disk.
