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.
I know two free softs would do dynamic disk recovery best.
for partitions recvoery, partition recovery would be the best
for partiton data recovery, data recovery wizard can do the best
hopefully it can help more ;)
just have a try to fix your partition
the disk management utility may help you, check the drive letter and assign it.
if your partitions cannot be shown in the disk management utility, maybe the data in the partitions have lost
for sure, backup work can guarantee total security
