My hard drive has given me problems for a while now and it has gotten pretty bad. My C drive is usually at 100% active time and is very slow, I have around 180 Mb/s download rate but it takes me a couple hours sometimes to download a gig of data. I've ran chkdsk /r /f, I checked with malware bytes didn't find anything, and used ccleaner for my registry and C drive and nothing. Im not sure if i have some corrupted sectors in my drive so I have to replace it or is there something happening? Any input is greatly appreciated, thanks for your time.
