A great hard disk monitoring application. I used it to more closely examine the S.M.A.R.T. status of a hard disk drive that I was informed was on the brink of failing. The Intel storage controller driver that informed me of this (RapidStorage for Enterprises) did so flawlessly, which I am immensely thankful for, but it did not give me any more information apart from the fact that the drive was "at risk".
You can get CrystalDiskInfo in a portable archive if you want, so you don't need to install anything. That's always a very important offering for anything related to drive health.
The interface is very clean and simple to use. You can instantly see where to find the information you need, even if you're not knowledgable about drives and their internals. Just click the drive you are interested in (any partitions/drive letters it holds are displayed to help you). A LED shows you at one glance if one drive reports critical S.M.A.R.T. information, i.e., thinks it's about to die.
Upon clicking a drive, you get all the basic information such as model and serial number, total size, firmware version, cache size, rotational speed, etc. You're also told what interface it uses (helps you make sure that, for example, a S-ATA II drive is not erroneously using S-ATA I in backwards-compatibility mode, which would make it slower than it needs to be), and what features are enabled (most notably, to make sure that an SSD has TRIM enabled, and a hard disk doesn't, which can otherwise be pretty hard to find out in Windows).
Most important are of course the diagnostics. You get a big display of your drive's overall status—a big blue 'good' or a big red 'bad'—its current operating temperature, how many times it has been turned on and how many hours it has been in operation (very interesting!) A listbox in the bottom shows the detailed S.M.A.R.T. information with their warning limits, so that you can find out exactly why the drive reports that it is going to fail, and whether you should take it seriously (you probably should). You can also export all this data for all the drives in your system into a handy text file, which includes the raw binary data from with the stats are extracted. A good snapshot if you need an expert's opinion.
There's more to the application still. You can have it start with your system and run discretely in the background, making its presence known only if it detects something bad happening. You can even let it install a Windows Gadget showing diagnostic information.
I will likely keep this tool around even though both Intel RapidStorage and Windows 7 itself informed me of the S.M.A.R.T. warnings, because the additional information and diagnostics it gives are both nerdily interesting and helpful.
Does what it says, checks your HDD/SSD SMART health, nowadays software even from known names come with garbage included, so marking this tool as "suspicious" is a little misleading, the tool itself is really lightweight and easy to use, I used it during these days, it actually asks to install skype, not conduit anymore.
Good but you must make little bit edit like a if you S.M.A.R.T values is wierd go function>Advanced Feature>RAW Values> and chose 10 [DEC] options and tada S.M.A.R.T values shows normal.
I use the portable version, since it works out of the box, without the need of installation.
Lightweight and full of features is a must have to every computer that uses mechanical or SSD drives.
Lifesaver when the disk health is in danger and warns the user about the eminent failure.
Be aware that the 32bit version has a lot more features (both 32 and 64 in zip (exe?)):
I use app to monitor SMART registers. It is quite fine, especially it is useful to review values in diagrams to estimate future behavior.
App is marked as suspicious here. It seems this is about installer which is marked as "w/ Ads" on the home page.
I have installed app from zip-file; I did not want to have ads.
I unpacked it and it works as expected.

CrystalDiskInfo is an excellent S.M.A.R.T. diagnostic tool with full capabilities and a nice user interface. It's a shame it's flagged as unsafe here on AlternativeTo.net because it's a great piece of software, it just has an optional Conduit toolbar bundled with the .exe installer version.
Unfortunately nowadays that is not uncommon, even Java Runtime Environment does this with their McAfee etc. bundled crap on the installer.
