I haven't gotten any indication until today that, for some reason, my RAID 1 won't read one of my HDDs. I tried booting from both drives separately, and both will boot and run, only one seems to be "updated" and the other one seems to be "behind" by a few days/a week or so. When booting up from the disk that was "behind" it says it was recovering from an "unexpected shutdown" and I started her up in normal Windows, and of course that's when I noticed everything was behind and not up-to-date.
I'm using Hardware RAID on the motherboard itself.
My motherboard is an Asus M4A89TD Pro USB3.
When checking the RAID menu on startup, it seems to only detect one drive and when going into BIOS it seems to read RAID and the one drive separately.
How badly did I mess this up, and how do I fix this? Did something get corrupted?
Most importantly, how do I fix it without losing my data? Would I have to buy a whole new HDD?
Help is very much appreciated, especially if it's in a timely manner.
