I imaged my win7 system disk via ntfsclone + dd (mbr) to one of my Win7 Dynamic Disk RAID1 disks from within the Ubuntu LiveCD instance (only wrote to one of the disks in the win7 RAID1 array). I did this with success and was then able to reload the image into Virtual Box after fully installing Ubuntu 11.10.
Now, I'm trying to setup the RAID1 software RAID in Ubuntu (installed over old win7 system drive) via mdadm and I'm wondering if I can do this and have it resync the data on both drives without destroying the Dynamic Disk RAID config and without any data loss (most important)?
I realize I should have probably done this from the get go (even in LiveCD)... if this isn't possible - perhaps, I can re-partition the second RAID disk that wasn't written to and then have it resync? Or should I use dd to re-image first RAID drive -> 2nd Drive and then run mdadm?
Goal here is to have a dual boot Ubuntu/Win7 system which can both read/write from the RAID1 array... also, don't want to use fakeRAID, rather, software RAID
