I have a problem with rebuilding a RAID1 array.
Recently my W8.1 setup (Gigabyte X58A-UD5 Motherboard) showed an error in Disk 1 on reboot - in the configuration utility.
I bought a new disk, thinking that would be the best approach, and began the rebuild from Disk 0 to Disk 1.
At what seemed to be the end of the process, and after trying to log in (W10 login screen), the machine rebooted - did it crash?
This time, the Disk 0 (which was the good on) showed an error.
I removed it from the array and am now running with my new disk (Disk 1) only, which seems to be ok and boots the machine.
Physical Disk 0, which was immediately placed "offline", and I changed to online (Signature Collision), is now unusable. It can't be accessed. But I should be able to format it as that option is available in Windows.
I have not removed the RAID array. I want to rebuild it.
I haven't manually upgraded anything on this machine which is now nearly 4 years old. The intel utility showed an upgrade for the chipset, but it failed to install.
The configuration utility is older, and seems to be the Intel Matrix Storage Manager - the system shows IC8H version SATA RAID controller, and the X58 chipset.
