Raid 1 partition recovery after replaced motherboard

#1 Post by fwak » 12 Sep 2015, 23:30

I replaced my dead motherboard with a newer one, same brand but it has newer chipsets (AMD 7XX --> AMD 9XX),
and (ugh!) UEFI, which tried to make the raid 1 into a boot disk (raid 1 is data only, no OS). To get boot order correct I finally had to re-install Windows 10-64 on the SSD.

Windows sees the (raid 1) disk as raw, and wants me to format it (I have not).
TestDisk says invalid NTFS boot and invalid FAT boot sector.
TestDisk says hdd seems too small.
Deep scan: FAT16 shows 1190 GB, NTFS shows 557 GB. (Actual identical disks in raid 1 are 640 GB each).

"Add partiition": I have not b/c I'm not sure what would happen and don't want to make things worse.
"Load backup": there is no backup

Not sure where to go from here.

I was able to extract 1 GB of files via the trial version of EaseUS, but that is a small fraction of what remains there.
