I have a 5+ years old WD 3TB hdd which was working fine last night. OS is on an SSD. I did a scheduled malwarebyte scan last night then performed a defragment process. However the the defragment process was taking way too long lik 3/4 hours. I got suspicious. I see even after cancelling the process; disk use is 100% and the disk was very slow. I tried to restart the pc but it was just stuck on the shut down screen. I forced turned off the pc and start again; and waitied for 40 minute on windows loading screen. Then I tried disconnecting the hdd and everything worked fine. Is my hdd gone/broke ? While the pc is on, i tried connecting the hdd; and in my computer it appears but the loading animation continues for indefinitely. Tried running Recuva/Malwarebyte but they dont run. As soon as I disconnect the hdd, they all run. About a year ago, I had the same problem with another 3 tb hdd; I though it was gone. Now I see same problem again so I was wondering if its anything else.
