Hi,

I've set up a computer with a raid 5 array which was working well at first. I think I may have done something I wasn't supposed to though, because in the past day, the Intel Matrix storage manager has initialized the volume, and now it is rebuilding the volume extremely slowly. I have not replaced any of the hard drives.

I'm using a Gigabyte motherboard with an onboard Raid controller. In addition to this, I have installed the Intel Matrix storage manager.

Things that I have done in the past that might be related are defragmenting the hard drive and using the disk cleanup utility to clean up previous restore points and shadow copies. Does the issue have to do with the fact that I used disk clean up?

I used the disk clean up utility becaues there was a lot of unaccounted for used up space on the drive.

Thanks for the help

I also just called WD tech support, and they told me that defragmentation is not recommended for a raid 5 array. ?

Remember that even though raid 5 spans many spindles, it is still treated as one logical drive. So with that, defragging is always a good thing. It only becomes a burden when you have to do it more frequently cuz your data keeps changing on you. To combat this issue, you must make sure that you defrag often, during off-peak hours. i recommend diskeeper's "set it and forget it" feature set. It work wonders on all of my windows drives!!!...

But,

Cleanup can do some damage especially if you do it to soon! Like iof you just installed windows and did cleanup thats bad. If you just installed a lot of programs and did clenup that is bad as tsome files need to stay on the drive for at least 2 hours..
