Defragmenting a RAID 5 at DVinfo.net

Benjamin Smith · May 11th, 2011, 04:14 AM

Hello all

I am backing a load of stuff off my edit machine this week and when I've freed up some space and had a general tiny I want to defrag the RAID.

I wondered if anyone has any advice on applications to do this, or whether I should use the built-in Windows defrag tool?

The system is Windows 7 and the RAID is set to RAID 5 (3 physical disks). It think it's about 4Tb.

Thanks in advance,

/ben

I hear alarm bells - I have a raid 5 and wouldn't let windows defrag within a mile of it. What makes you think it's fragmented? I'm pretty sure Raid 5 uses disk space in a completely different manner. Hopefully someone who really know what's going on can chip in. In the meantime - DON'T DO IT
