Need to defragment my Windows 2000 Server's RAID hard drives at boot time

I would like to defragment my Windows 2000 Servers hard drive at boot time to ensure the best defrag when Windows isn't loaded.

The server has a motherboard that has an on-board quality Promise RAID controller. Attached to the two channels are two identical 80Gb hard drives. They run on RAID 1 mirroring which is handled by the hardware.

What tool is safe to do this?

Thanks as always,

Lee.

I would check out Diskeeper from Executive software ( http://www.executive.com/coverpage.asp ). Rather than doing a start-up defrag (that would probably seriously jack up your performance) you can set it up to do real-time defrag....that way your drive never fragments in the first place. It also keeps your pagefile defragged :)

Data loss can hit a business in any number of ways. In reality, companies should expect to lose data at some point. The challenge is having a plan to recover from such an event.

I would check my manual on the RAID system to see if this does not have either an  automatic or a manual defrag facility.

Use only Diskkeeper from Executive Software on hardware RAID.

Hardware RAID is always fragmented - it's the nature of the technology.  

Executive has spent a ton of money perfecting their defrag tools from servers using hardware RAID - personally, I wouldn't trust anything else.

Just my opinion.

I agree with Netman, - unless you actually experience performance degradation, never mess with a hw RAID using the disk manager.

Have you installed RAID tool for your adapter, - most come with some sort of tool which will  give you access to the log where you can see if  there's any problems.

All defragmenters use the same mechanism to defragment files.  They all call Microsoft's defrag APIs and it is the file system itself that actually performs all of the file "moves".  ANY defragmenter can safely defragment RAIDx.

Just the facts.

Furthermore RAID isn't always fragmented.   and furthermore again Diskeeper says it won't install on 2000 server/2003 server/nt server.

I think that's a somewhat weak answer
