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.
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.

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:
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).
It is a collection of utilities that work together to keep your Mac healthy, fast, uncluttered, and virus free. Drive Genius scans for problems automatically using the DrivePulse utility. It also enables you to periodically scan for problems manually and repair a variety of hard drive issues.
To repair your startup disk you will need to boot from another drive. Drive Genius facilitates this by creating a secondary boot drive called BootWell that contains the suite of utilities. To cover all of those features you would normally need to purchase several products.
I took the screenshot below six days later. The status of most of the scans is still Pending. The Physical check on my drive is still only 2.4% complete, so it takes quite a while to thoroughly check everything systematically. Every file I access, however, is checked immediately.
My personal take: Fortunately hard drive problems like this are fairly rare, but when they happen, repair is urgent and important. I love that Prosoft can give you early warning of potential problems, and is also competent at repairing a range of hard drive issues.
Drive Genius has a number of other utilities that are able to help you work with your drives and files. Two of these are designed to help free up hard drive space by cleaning up duplicate files and locating large files.
Drive Genius constantly monitors your hard drive and fixes issues before they become major problems. It scans for viruses and automatically moves infected files to the trash. It monitors for file fragmentation that slows your computer and pops up a warning. It does all of this without you lifting a finger.
Besides that, it includes a comprehensive set of tools that scan for and fix problems, free hard drive space, and clone, partition and securely erase your drives. These features are essential if you require a reliable, safe and secure work environment. If that sounds like you, then I highly recommend Drive Genius. The program offers excellent value for money when you consider all of the functions it can perform.
A compliment to Data Rescue 3, Drive Genius is less about repair and more about diagnosis and defrag. You can scan a drive for sector problems caused when the platters of a drive do not place data correctly on a hard disk, which can then slow your computer. A suite of helpful tools helps you repair problems by running defrag (this does not restore lost data though) and partition drives so you can separate, say, a Mac OS drive from a data drive. A brand new tool called DrivePulse reports any errors that occur as you are using your Mac for everyday tasks.
Drive Genius does not bother too much with superfluous graphics or fancy visuals, although the app does provide some nifty animations (similar to those in Data Rescue) that show how a hard drive platter might spin and bits flying across the screen during a scan. However, the options are arranged for quick access; you can click icons or choose tools from a drop-down menu.
In several scanning tests with a normal drive in a MacBook that is about three years old, Drive Genius found a wide range of sector errors. One note about using this tool: to correct sector errors, you will need to use the DVD version, which allows you to access your boot drive. You can use the version that runs on your boot drive to find errors, however. Scans took about 40 minutes on a 160GB internal drive and about that same amount of time to defrag and fix problems.
I noticed, after a thorough defrag, that my MacBook felt just a hair faster, especially for disk intensive tasks such as copying a file to a network drive and installing a large app like Photoshop CS5.
Prosoft added a few extra features to Drive Genius to make it more compelling compared to competing defrag tools, including those that come with every Mac. (Note that the Mac does a better job of maintaining drive integrity just on its own compared to a PC.) Pesky sector problems do arise, and after several days or testing we never ran into a problem that the program could not resolve.
The new features are not necessarily major, but do help in the diagnosis process. You can now verify a disk before running a defrag, a feature that is actually overdue for a tool like this. (Verification finds errors but does not fix them.) The program does not run faster than the previous release per se, but as a 64-bit program, it will run faster on systems with a lot of RAM because of how 64-bit software works. There is also more feedback about your drive (including details about bad sectors) than the previous release.
Drive Genius is designed to repair damaged hard drives that may be causing problems or frequent crashes on your machine. However, it's also suitable for those that just want to keep their Mac hard drive in tip top condition catering for those that want to partition, defrag, and even copy the contents of their drive. If you need to test or benchmark your Mac, Drive Genius has a bench test and surface scan feature that allows you to scan for bad sectors that are causing problems. Finally, there's also a handy shredding tool for destroying files and documents that contain sensitive data.
What attracts most users to Drive Genius is the fact that it's one of the few Mac utilities that will physically scan for bad sectors. That's also accompanied by one of the best interfaces I've seen on a maintenance program for the Mac since the arrival of MacKeeper. Drive Genius has an animated user interface that's a little like cycling through albums in iTunes. Each of the functions such as Defrag, Benchtestand Scan animate when you select them. There's nothing complicated about executing each task either - just select the drive you want to scan along the left hand side and click Start.
As in "not move files and programs"? That's just reinstalling Windows. The license is attached to the motherboard, not the drive, so you can install it as many times are you like on whatever storage and it will activate properly.
You probably (somehow) deleted the Windows partition from the hard drive. If there was anything important on the drive that's not backed up somewhere else, DO NOT DO ANYTHING ELSE and send to a data recovery service.
For future reference: it is possible to migrate a larger disk to a smaller disk as long as the larger disk doesn't contain more "stuff" than the smaller disk can fit. Sometimes this will be a two stage process where step 1 is to shrink the partition on the larger drive to make it small enough to migrate, then step 2 is to perform the migration.
