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.

Go to the site liked above and see if someone has mentioned your particular drive and what they report as to what works best on your drive. And see what works best on any DVD Players you may have.
Knowlege is Golden, and obtaining the knowelge yourself makes it stick, at least in my case.
