Windows 7: Software (WinXP) raid1 on Windows 7?

Software (WinXP) raid1 on Windows 7?


it's possible to use raid1 builded on Windows XP SP2 32-bit (SW raid1 manually enabled in Windows XP by re-writed this files: dmadmin.exe, dmboot.sys, dmconfig.dll) in Windows 7 RTM 64-bit? So if Windows 7 can support raid1 natively like Windows Server 2003
I mean use without rebuilding raid1 array or something like that. Simply install Windows 7 and start to using raid1 which has been created in WinXP. It's possible? Thanks alot for any information about this problem.

I have no direct experience with Windows software RAID, but I would think that any Windows native filesystem configuration supported in XP would also be supported in Win 7. However, although I do see striped and spanned volumes, I do not see an option for creating mirrors, though they are mentioned in the disk maintenance help. I'm using Home Premium though, maybe in Pro and Ultimate.

Ok... I will try Ultimate version.

EDITED: So Ultimate version support raid1 (Mirror) - told me friend - he test it on vmware.
EDITED2: I tested too and I have no problem with SW raid1 created in WinXP Pro. Everything seems to be ok in Windows 7.
