Import foreign disks in RAID-0 config

2

1

I've to import 2 disks in RAID-0 into another computer. Both source and target PC run Win8. In the target PC I see two foreign dynamic disks and when I right-click on any of those and then I select "Import Foreign Disks.." a new window appears listing both disks with checkboxes. However, only one checkbox can be selected at a time and then if I click OK an alert window says this scary message:

enter image description here

So what am I supposed to do to import both safely without losing data? I'm also afraid it could be a wrong message from Windows but please consider I cannot risk and I have no other disks to perform a deep copy.

What drives are these, are they two SATA drives taken from another machine? How was the RAID setup in that other machine? My guess is that it was hardware RAID which has not been replicated to this PC so Windows is seeing each disk independently, if this is the case you need to create the RAID array to mirror the old machine they came out of most likely at hardware level so Windows only knows of the one RAID volume. – CharlesH – 2015-05-29T12:58:39.727

They are two SATA drives that were in software RAID-0 – Mauro Ganswer – 2015-05-29T13:14:28.567

Ah ok software RAID-0 what software RAID was it? Computer Manager Disk Management Spanned Volume? – CharlesH – 2015-05-29T14:03:45.590

Yes I set it from Computer Manager, and it is a striped volume (see also picture) – Mauro Ganswer – 2015-05-29T16:28:59.323

Normally windows would see both disks as a raid set as soon as they are seen in disk management and allow import or may even import them automatically, it sees a problem with one or both drives, do they still work as raid in the old system? – Moab – 2015-05-30T12:56:38.103

The old system is no more available unfortunately. However, I do not think Windows it will import automatically. I remember that another time I had to move a dynamic disk (it was in RAID-1) to another system, the disk it was still marked as foreign and I had to do it manually from disk management – Mauro Ganswer – 2015-05-31T17:40:15.273

At the end I decided to try it out without caring about the scary alerting message. Hence, I selected the first disk to import and when the message appeared I clicked "yes". Then I repeated the procedure for the second disk. Again the message appeared and I clicked "yes". After both foreign disks were imported Windows was able to automatically recreate the RAID-0.

I had two HDDs in a striped volume and had the same problem (I didn't click "Import Foreign Disks" though) when connecting them to another PC but it worked after I reset my PC with which I set up the striped volume. It also still worked after I formatted my PC and reinstalled Windows 10 64Bit to it.
