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.
Striped (RAID 0) or JBOD, your best bet is to copy all the data off the device onto an external drive/device of sufficient capacity. Pull out all your old drives drives, install new drives, create array, copy data back.
Mirrored (RAID 1) or SHR - Pop out the bad drive. Put in new drive. Repair Array. Pop out second drive, put in new drive, Repair Array. Done.
