Have you disabled precaching and such? Unless you do that, memory consumption figures don't really make sense.
If your WD HDD is throwing off errors I suggest retiring it and not using it anymore. Run a backup of anything you want to keep and do a full reformat (a long, slow variety format, not the quick) and see if it helps in any way, although I would still treat the drive as suspect after that.
And you can update the firmware before doing a formatting or a "secure erase", though that may be useless.
One weird thing I did with a laptop, it went totally unusable but the bad sectors were at about the same place near the half of the drive.
So, I managed to install an OS on a partition that uses the second half of the drive and it was usable again. Launching a partition tool that scans the disk for partitions crashes the computer, so I doubt it can work with any OS installer.
chkdsk /r command in Windows. Open up a command prompt window and type "chkdsk /r x:" ignore the quotes and replace x with the drive letter of the hdd you want to check. the /r parameter sets it to repair mode and it'll automatically fix any bad sectors. Fixing means flagging the bad sectors as bad so that OS's don't use those sectors anymore. And, it doesn't mean the drive is bad if bad sectors are found. And yes, they can come from the factory with bad sectors and it doesn't mean the drive is defective, but often you can just get the drive replaced immediately under warranty. Drives come with spare sectors anyway so that if the disk controller finds them it can remap those bad sectors to a good spare sector. When the OS starts finding the sectors, it usally means that there are no more spare sectors left and the OS can just mark the sector as bad so that it's just skipped over in the future. Now if bad sectors just keep coming up, then yea it's defective. But i've had bad sectors found, ran chkdsk /r, and got another 7 or 8 years out of the drive before it died. AND, most of the time drives die, it's the controller board that dies, not the actual mechanics of the HDD. You can replace the controller board with another one from an identical HDD or very similar HDD and the drive is fine again. Anyway, just run chkdsk /r in command prompt and see what it finds. see how long it takes for bad sectors to come up again.
ClickEvery hard drive has bad sectors when they are produced. When the manufacturer initially sets up the drive, they record them in a special list, call the PLIST. This list is, to the most part, static. More bad sectors can be added to the list, but that requires special tools to make it happen. Then, there is the GLIST which houses the bad sectors that come along over the years of use. This list is managed by the hard drive itself. With the aforementioned tools, the GLIST can either be cleared out or transferred to the PLIST. To add to these lists, the operating systems (ie, Windows) keeps tracks of what it considers bad sectors and marks them as unusable.
So, yes, there really isn't much to worry about 2 or 3 bad sectors. However, the drive needs to be closely monitored because 2 or 3 bad sectors can very quickly turn into 2 to 3 million bad sectors...it really depends on the causes for the bad sectors being formed. If they are there because of minor media defects, that is one thing. If they are there as an early sign of failing read/write heads, then you want to watch out.
Now, to the software tools. I agree that the manufacturer's software tools are always best for each drive. Be sure to run the most thorough scan that tests each sector with a read and a write. This is usually done through a low level format. In doing such tests, be sure to backup your data, as the drive will be super clean when you are done. If done correctly, the data cannot be recovered, not even by a hard drive data recovery service.
Other tools that I have used are Drive Fitness Test by Hitachi which works with all brands of drives and is free and Quick Tech Pro by Ultra-X which is a commercial product that tests all your system hardware, as well.
Good luck with your drive.

We used to have scandisk, it looked prettier
I'll give you an illustration, this is how I can get 40 tabs open in a few minutes, full of worthless but very interesting crap, then I'll do something else and pretend to have "forgotten" about them.

My biggest grievance at the moment with Chrome is on my wife's PC. I haven't given her admin rights, and that's fine for everything, except that Youtube videos now refuse to run more than 17 seconds. After a while I tried running Chrome as administrator (shift right-clik / run as admin), and then it works fine. I don't like that one bit, to be honest, especially as browsers are one of the weakest links in computer security.
This almost looks like a feature, if the browser then displayed "stop fooling around with cat videos and go back to work!" (in a corporate setting)
That has to be a weird bug. The common security complaint about Chrome was that it's a browser you can install with user rights.
