I have a 3 yr old Samsung laptop which I thought was behaving properly. Today, Outlook froze and then as I tried to open other programs, each thing froze as well. I left it alone and things eventually sorted themselves out and the computer became functional again.
I looked in Event Viewer and I am seeing a LOT of disk warnings and errors, going all the way back to March. That's as far back as it goes, to the date when I installed Windows 10. (Laptop came with Windows 8 installed, I upgraded to 8.1 and then to 10.) This is in Hard Disk 0, which contains Drive C and several recovery drives.
The errors are mentioning ominous things such as "bad block", so the first thing I would like to do is actually see if the physical hard drive itself is failing. In looking at Settings, I see no indication that it is, it says the drive is healthy.
I've seen reference to software called CrystalDisk, but I would like to be assured of a safe download site for that, or is there other software someone here can recommend?
