I would let the RAID software see if it can fix the problems first.  I think there is a good chance to run chkdsk /r could blow your RAID.  make sure you have a good backup. Replace the disk and let it rebuild and hope the errors are fixed by the RAID contrller software.  You shouldn't need to run chkdsk on a RAID.

We've had issues with Dell servers continually showing predictive failures on disks in the past.  It turned out to be a known issue with the firmware levels on the disks.  The firmware and drivers for the PERC needed upgrading too.  I'd get yourselve on the Dell support website and look for firmware upgrades.

Thanks for the suggestions.
Do you think If i updrage the firmware that will fix the problem?
At present I have inserted new disk and is rebuilding but still shows predeited failure. got really confused.
If i upgrade the firmware after it finishes ,I will not loose the RAID / data  as this is production server though I have a backup but you know backus are like? please suggest.

There are never any 100% guarantees when it comes to RAID problem.  However I have never lost data by doing a firmware upgrade.  
I assume that this server is out of support with Dell, if it is on support, log a call, they can take you through the whole process.

Server is indeed out of support. I will take the backup and will do the firmware upgrade. what is your experience with the process how it does it?

Again, no guarantees, however I have seen the disk firmware / controller firmware upgrades fix this in the past.
The process for the disks is to download the correct ISO image from Dell and burn to a CD.  Then boot from the CD and let it upgrade the disk firmware in batch mode.  This should only take a few mins, the longest part is the server boot process.
The controller firmware can be done from within Windows, a reboot will be required thought.  It is best to make sure you are using teh latest drivers BEFORE you do the firmware.
Good luck!
