I can't believe I got such good answers so fast. Thanks guys, there is hope. I was afraid that it'd be a nightmare.
Yes, it is Windows 7.
It depends on the software, but it's possible it will repartition the drive exactly as it was before and leave the extra space as "Unallocated". You can then just allocate that free space when you get back into windows.Also, if I'm going from a 750GB HDD to 1TB HDD, will the new drive see the extra space or do I have to manually do something?
If you are using some sort on motherboard provided RAID solution then you should be OK to go into the RAID controller BIOS, tell it to break the RAID mirror and have two disks that are identical. I've done this morning than one.
What I did was first removed one of the RAID disk by physically disconnecting it. Then I went into the RAID BIOS and broke the RAID, leaving the connected disk as a non-RAID solo disk. Booted, verified everything was OK.
If it wasn't OK, I'd wipe that still-connected disk, restore the RAID disk and allow the mirror to be rebuilt. The RAID option is just a flag on the disk to identify it as a RAID disk. Nothing really special.
I am aware of this and I think it is more designed to cover liability than anything else. I unplugged a disk in a RIAD1 mirror into another computer and it booted just fine.What about the warning that if you change the raid settings that you will lose all data?

Confident that I hadn't lost anything, I destroyed the RAID that still had the second disk connected and nothing was lost. I then unplugged it and plugged back in the first disk and repeated the RAID destruction on it and again was left with two identical disks.
YMMV, of course.
