Drive usage is not normal to be pegged at 100 percent all the time. Maybe at bootup for a few minutes while things are finishing up booting and updates are being checked for, etc.In Windows 8 and 10, it's totally normal to see that number jump to 100% all the time.
I am experiencing system hang ups, sometimes it takes almost a minute to open up firefox. When it hits and stays at 100% I can't do anything.
I said "jump to 100% all the time" not stay at 100%. Usually, it's intermittent, but I've seen plenty of systems where everything was operating just fine and it'd jump to 100% stay there for 30 seconds or so and then drop back down. Then do it again in a few minutes. It's usually just from some background processes such as AV running. But, if it's staying there all the time that's a problem.Drive usage is not normal to be pegged at 100 percent all the time.
In that case I'd say you do have a problem. What is the specific HDD model? There are some that are prone to firmware glitches that will make them slower and slower until they totally stop.I am experiencing system hang ups, sometimes it takes almost a minute to open up firefox.
