Windows 7: How do I resize a partition on an existing hardware RAID0?

How do I resize a partition on an existing hardware RAID0?

Hi,

I have a single partition (E) on a 1TB hardware RAID0.

This drive contains some installed programs and data. I would like to resize the existing partition, and then create a new partition such that I have:

E: ~500GB
F: ~500GB

I booted from a YUMI USB multi-boot and opened Partition Wizard 7. In PW7, I see the two disks that make up the RAID0. One disk is shown as empty, the other is shown as full. When I select either, the option to re-size these are greyed out - in fact, there doesn't appear to be much I can do with these disks. I'm guessing it's because they are in a RAID configuration, or perhaps I'm missing something in PW7?? Are there other tools that might accomplish this job?

Am I better off wiping the existing partition altogether, and then re-partioning using DISKPART? The existing E: partition is imaged using Macrium Reflect. If I wipe the existing E: and then use DISKPART to reconfigure a new E: and F: from scratch, will Macrium have problems restoring the image to the newer, smaller E:? My latest Macrium image for E: is 147GB, so presumably Macrium won't have an issue restoring to a new fresh 500GB partition?

I realise that simply using the two seperate disks outside of a RAID0 is the easiest thing to do, but I have a specific need for the IO speed that the RAID0 configuration delivers which is related to my work.

Thanks,
Golden

Golden, it's not really within my knowledge base, but would this help - there is a free download - I have heard others speak well of it:

Brilliant, thanks Irene. If I don't get any other obvious solutions, I'll do a backup of everything, and then give this software a crack.

Cheers,

Decided to post on this because I stumbled upon it with the same question. This no longer works. They want a license for the software. So it is not FREE.
