Should be, iv used hdd with had sectors all over the place and not cared over the years though sometimes the odd program gets zaped with a bad sector, system should be able to run fine with some as well as long as the bad sectors are tagged so the Os doesn't try and read or use them, i know in ms-dos this was possible to do on a fat32 drive, don't 100% know how that topic works on ntfs drives, as well i only learned the other day something new about win10 and that is that its not possible to disable vsink in win10 with out going full screen, its a real pain in the ass topic.
That why in the past last we chated on this forum and you did 3dmark benchmarks your score was so low "best guess", as well iv bin seeing other with fps problems in win10 of late in this forum mostly from trying to play older games, don't know whats going on with this topic but your not the only one and as yet no one seems to know whats going on and no one seems to have a fix for it.
Plz don't feel like a loser for any reason, in the end we all only know more then some but less then others, its all relative and every story has to start somewhere.
And i wouldn't change a hdd just cus you have one bad sector but when you start seeing this topic too much that might mean the hdd is on its way out and its time to back things up.
As well my old recommendation still stands, change to win7 64bit, probably fix all your problems.
