Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
The raid controller on my motherboard died. If I buy a new motherboard of the same model, can I set up the array with the same parameters and still have all my data?
You shouldn't need to set it up beyond just enabling the RAID BIOS -- it should auto-detect it once RAID is enabled. Recreating the RAID could in some cases wipe your data with a fresh empty array.
Implementation details and state and luck vary though, so there are no guarantees. In some cases you may have to re-define the array (in Windows) to get it working again.
