Hi schneekerpeeker ,
I agree with Tyrod this is not normal you may have a hard drive on its way out , my advice would be to backup any data that you want to keep and
replace that drive.
6 months old makes no difference , i have had HDD's dead on arival , some last 3months , some last 12 months others 10 years or more
If the hard drive is only 6months old you may be able to RMA it to the manufacturer.
1TB drives are fairly cheap these days so to replace it wont cost an arm and a leg
