wizisi2k: See what the SMART information says about the drive. Green means ignore the message. Yellow means think on backing it up. Red: BACK THAT DATA UP RIGHT NOW!!! (drive is going to fail). Windows telling you to back the data up is not a good sign (you may hear why with it running much longer
Health status is bad. Its says ''bad'' in red just like you said lol.
Shadowstalker16: Scanned with Comodo free AV and found nothing. Another tihng I find is constant 100% HDD usage in task manager. I recall someone saying it might be AV scanning new files but I haven't downloaded anything new other than the OS. Any advice? The HDD thing is making everything lag.
vanchann: It's a problem that affects many systems.
I wasn't able to solve it too. In the beginning I was thinking the newly installed system needed indexing files, but it wasn't the case.
It's not your AV. Some services just don't work right. I had disabled many things, but nothing helped. I think it's a "per system" problem, without a general solution (except removing Windows 10 altogether).
EDIT: It isn't a hardware (SMART) problem either - not in general at least - but if HDD continues to work at 100% rate it eventually will be.
Its a SMART problem as well now apparently. Interesting thing is that I didn't have the HDD working at 100% problem last night but do have it today. Seems random. I'll try a restart to see if it changes.
EDIT: reboot doesn't help. But now I wonder why it wasn't stressing my HDD yesterday.
