@Magic_The Make sure you have a full image of your hard drive in case it fails suddently, so when it does fail you can restore the image to the new drive. It would be a good idea to purchase a new drive now to have ready for when your current drive fails. Hard Disk Sentinel is showing serious problems with your hard drive, but nothing critical at this stage. This means that while the drive is starting to fail, it looks like it it is not going to suddently die just yet. I use Hard Disk Senitnel my self, and really like that is gives a detailed descrption of the current state of the hard drive. If it was me, I would buy a new drive right now (hard drives are cheap), and then clone your failing drive to the new drive and stop using the old one. Since your hard drive has developed problems, with further use it will only get worse, and it makes sense to switch to a new drive now before the current drive failes completely and use risk losing data,
I use hdsentinel myself and ran at 1 day lifespan left for a few months until it died. Buy a new hard drive but it's not urgent ime yet
