Sorry to hear about this. It used to happen to me with old HDs and even the new SSDs but now someone told me to use CCleaner, it actually fixed 2 HD errors we get in 2 computers in the house, both have SSDs. We were ready to having them replaced but we tried CCleaner. I don't know if this makes sense but so far, it worked for us.
It works now, after a chat with Seagate... but thanks for the tip!
