In circumstances where a file name is lost, the data is still there, but not accessible, Rebuild may be able to list lost file names to the file data again. (Notice to macOS 10.13+ Users: The Repair feature is not supported on APFS)
The Malware Scan searches through files and downloads for known malware. The malware database is updated multiple times a day. In addition to running scans manually, DrivePulse will automatically scan downloaded files. Automatic download scans are only performed for certain well-known locations. Downloads saved outside of these locations will not be scanned automatically.
BootWell creates a special secondary startup drive that can be used to maintain your startup drive. A BootWell Drive is required to use the following tools on your startup drive: Defragment, Repair, Rebuild, Advanced Physical Check, and Whole-Drive Secure Erase. The first initial boot into a BootWell created on macOS 10.11+ may take up to 30 minutes.
Add, delete, hide, expand or shrink OS X partitions so you can organize your Mac hard drive more efficiently. Repartition enables you to manage (shrink, expand, shift, delete, hide, reveal or customize) partitions (volumes) on your hard drives. Unlike traditional methods of backing up, erasing and repartitioning the drive, Drive Genius allows you to expand or shrink partitions without erasing them. (Notice to macOS 10.13+ Users: The Repartition feature is not supported on APFS)
Malware Scan
The Malware Scan searches through files and downloads for known malware. The malware database is updated multiple times a day.

Downloads saved outside of these locations will not be scanned automatically.
Repartition*
Add, delete, hide, expand or shrink OS X partitions so you can organize your Mac hard drive more efficiently. Repartition enables you to manage (shrink, expand, shift, delete, hide, reveal or customize) partitions (volumes) on your hard drives. Unlike traditional methods of backing up, erasing and repartitioning the drive, Drive Genius allows you to expand or shrink partitions without erasing them.
Secure Erase
Overwrites all data using one of five secure patterns designed to make data recovery near impossible, it then creates a newly formatted drive or deletes files and folders.
Initialize
The Initialize utility prepares new drives, or erases old drives, for use with macOS. Drives can optionally be initialized for use with Windows / Camera cards or for use with legacy PowerPC Macs.
*Following features are not available to macOS 10.13+ users: The Defragment, Repartition, and Rebuild utilities are not supported on APFS and a Separate Boot Drive is needed to perform Physical Check and Speed Test.
I used COMMAND-I to change the file permission to READ AND WRITE and then used the VI editor in Terminal to "comment out" every line of the file by adding a "#" at the start of each line. Then I wrote out the file.

Also, again for whatever it's worth, I use an app called Tinker Tool System. It can be found here. It does what I need it to do, for about 15% of the price of Drive Genius:
Whenever you remove system modifications, they must be removed completely, and the only way to do that is to use the uninstallation tool, if any, provided by the developers, or to follow their instructions. If the software has been incompletely removed, you may have to re-download or even reinstall it in order to finish the job.
Trying to remove complex system modifications by hunting for files by name often will not work and may make the problem worse. The same goes for "utilities" such as "AppCleaner" and the like that purport to remove software.
Keeping up to date is especially important for complex software that modifies the operating system, such as device drivers. Don't install such modifications unless they're absolutely necessary. Remove them when they are no longer needed. Before installing any Apple update, you must check that all system modifications that you use are compatible. Incompatibility with third-party software is by far the most common cause of difficulties with system updates.
As a rule, you should avoid software that changes the way other software works. Plugins for Photoshop and similar programs are an obvious exception to this rule. Safari extensions, and perhaps the equivalent for other web browsers, are a partial exception. Most are safe, and they're easy to get rid of if they don't work. Some may cause the browser to crash or otherwise malfunction. Some are malicious. Use with caution, and install only well-known extensions from relatively trustworthy sources, such as the Safari Extensions Gallery.
Only install software that is useful to you, not (as you imagine) to the computer. For example, a word processor is useful for writing. A video editor is useful for making movies. A game is useful for fun. But a "cache cleaner" isn't useful for anything. You didn't buy a computer so you could clean caches.
Never install any third-party software unless you know how to uninstall it. Otherwise you may create problems that are very hard to solve. Do not rely on "utilities" such as "AppCleaner" and the like that purport to remove software.
Whenever you install new fonts, use the validation feature of the built-in Font Book application to make sure the fonts aren't defective and don't conflict with each other or with others that you already have. See the built-in help and this support article for instructions.
In OS X 10.7.5 or later, downloaded applications and Installer packages that have not been digitally signed by a developer registered with Apple are blocked from loading by default. The block can be overridden, but think carefully before you do so.
A common mistake is adding more and more large files to your home folder until you start to get warnings that you're out of space, which may be followed in short order by a startup failure. This is more prone to happen on the newer Macs that come with an internal SSD instead of the traditional hard drive. The drive can be very nearly full before you become aware of the problem.
While it's not true that you should or must keep any particular percentage of space free, you should monitor your storage use and make sure you're not in immediate danger of using it up. According to Apple documentation, you need at least 9 GB of free space on the startup volume for normal operation.
To use a Mac effectively, you have to free yourself from the Windows mindset that every computer needs regular downtime for maintenance such as "defragging" and "registry cleaning." Those concepts do not apply to the Mac platform.
A well-designed computing device is not something you should have to think about much. It should be an almost transparent medium through which you communicate, work, and play. If you want a machine that needs a lot of attention just to keep going, use a PC, or collect antique cars.
Tonight, in a (failed) attempt to access and perhaps repair a stubborn external hard drive that refuses to mount, I installed the app "Drive Genius" v4 (I purchased Drive Genius a few months ago, before I had this current Mac, but anticipating I would want to resurrect that external drive - never installed or used it until tonight). Drive Genius turned out to be completely useless for that purpose (I had v4, I guess there's a newer v5 for Sierra), and I soon gave up and concluded that I don't want Drive Genius on my Mac. The app has an Uninstall feature, so I used it. I *think* it removed all the bits of the program, but I wanted to be sure. So I downloaded and ran the EntreCheck utility (results copy/pasted below).
This is a brand new 27" iMac (less than a week old). It only has a handful of items installed on it (mostly some Adobe stuff, Chrome browser, and a couple minor utilities). Very little in the way of data files, so worst case, I could wipe the thing and no big loss (although I don't think that's called for). I will set up multiple cloned backups soon (my attempt to fix the external HD was a step towards that, but I'll be using different hardware). And I'm going to load up on RAM (yes, I know, the stock 8 GB it came with is minimal). Before setting up backups and adding RAM, I wanted to ensure I had a nice, squeaky clean setup...so I'm hoping I can confirm all the little bits of Drive Genius have been completely cleaned up.
Hardware is a new 27" iMac (Late 2015) running Sierra 10.12.4 with (I think) latest updates. I'm not having any trouble with it, just want to ensure it stays that way. Thanks in advance for help confirming I've successfully removed all of Drive Genius or guiding me on what's needed to complete that task (and I'll post a question about trying to resurrect the external HD in a separate thread).
Yeah, it didn't take long for me to conclude that DriveGenius was probably junk that should be avoided (I quickly noticed grammar errors in some of the screens, which looked like the UI strings were written by non-native English speakers, although the developer claims to be 100% US-based...not that there's anything wrong with non-native English speaking developers, I know a bunch that are great, but it just suggested a general carelessness if they didn't bother to proofread the text in their app).
