I installed Windows 7 on a system with a pair of 1 TB drives "C:" and a 500 GB drive "D:". I am using mirror function built in to Windows 7. I don't like hdwe RAID, as I may not be able to replace a failed controller. Unexpectedly, part of Windows got on the small drive instead of the mirrored pair, and I can't boot without D:. Disk Mgt reports D: has System, Active, Primary Partition; while C: is Boot, Page File. MS support Indian says I need to reinstall Windows after disconnecting D:, and everything will be OK. (I tried, but Install wouldn't let me - I guess I need to format the disk, and I really don't want to). MS support didn't seem too knowledgeable so I'm not confident. I have questions remaining:
!. Can Windows 7 even boot from a Windows 7 mirrored drive? I've read on forums that OS needs to be on another drive, that is not part of the mirror, which would sort of render the mirror meaningless. I don't want to have to reinstall Windows after a failure - been there, done that. Booting from a non-mirrored partition on a physical drive otherwise mirrored wouldn't help. Maybe I just need a Seagate FreeAgent GoFlex Desk?
2. Last comments notwithstanding, can I move the system from D: to a partition of C:, rename that partition D: and disconnect old D:? I was thinking of using MiniTool Partition Wizard, but first I need to break the mirror.
