SBS2K3 - Bad sectors on RAID 1

Our server has three disks - one for the system and two disks setup as
RAID 1 array for our data.

We have 652 bad sectors now being reported for the data drive in
Windows. CHKDSK has been run with the /R switch, so I think the bad
sectors are now identified and marked as 'do not use'.

Can we / should we ignore this now, and just monitor that the bad
sector count doesn't increase?

The RAID 1 is via Dell hardware, so I am unsure how to tell which disk
is the faulty one (or in RAID 1 are the bad sectors on both?!).

I guess I can physically remove one disk and run CHKDSK against them in
turn, but in doing this will I destroy the integrity of the RAID 1?


Thanks for any suggestions.

Cheers

Rob

if you have sectors going bad...this disk is done for...it will only get
worse. resolve it now before you data becomes corrupt and not accessible

Maybe look for non-HDD related drive volume hardware issues. Poor cabling
or dodgy power supply maybe. I have seen a noisy PSU generate intermittent
problems with several HDDs at once.
