Can I move existing Windows 7 setup to a RAID-1 array?

2

1

I have a the following setup: machine with one 1TB hdd and with W7Ultimate installed on that drive (with RAID in BIOS).

Now I want to make it running as RAID 1, so I have two additional similar 1TB WD Reds.

Is there some easy way hot to do it? I tried HW switch to RAID 1, but it will format the drive, so I tried to clone existing OS into it, but it will lost that RAID settings. I also tried to make RAID 1 in Intel Matrix storage in Windows, but it will says, that second drive is not big enough, etc and cannot be used for RAID. Also I tried to convert both drives to dynamic type, but obviously Win won't boot from this type of units.

screen from diskmgmt

I'm slowly discovering, that it may not be possible.

Could you post a screenshot of Disk Management with both drives connected? (You can launch that with diskmgmt.msc.) – Ben N – 2016-12-06T16:13:22.200

@BenN sure I can, but it depends with which configuration you mean. I'm preparing these drives in my own computer via docking station (cloning from original 1TB Blue), so there are 2 additional 1TB RED drives. – koudy_cz – 2016-12-07T07:41:03.637

OK I added diskmgmt screen with some description. – koudy_cz – 2016-12-07T08:57:41.063
