Most users are satisfied with the hard drive utilities that ship with Windows--especially the more powerful partitioning and defragging tools found in Windows Vista and 7. Since you're reading this, though, you're obviously not a 'most' type of user. Here are our ten favorite free utilities for partitioning, monitoring, and optimizing hard drives (as well as a few inexpensive for-pay alternatives). Despite offering some high-end features, these downloadable programs won't bust your budget.
(For links to all of the downloads in one convenient list, see our '10 Best Free Hard-Drive Utilities' collection.)
Partitioning
Microsoft's DiskPart--included for free on each Vista or Windows 7 installation disc--is a perfectly viable tool for manipulating FAT and NTFS partitions, but only if you're in a command-line kind of mood. The vast majority of the time, I want something fast and graphical that supports all file systems.
Of all the partition utilities I've reviewed, Parted Magic (now in version 6) remains my top pick--not only because it has the free Gnome partition tool (GParted), but also because it has Memtest86+. I'd say that I encounter about one memory problem for every three hard drive problems, so it's nice to have that memory-diagnostic tool around.
If you don't need memory testing, or if you just want an alternative Linux partitioning boot disc, GParted Live is a slightly lighter-weight boot disc that also supports booting from a USB flash drive or an external hard drive. You need to visit the command prompt twice during the boot process, but I have on occasion found that GParted Live boots when the Parted Magic disc will not--and vice versa.
Offering an extremely small footprint and very quick boots, Partition Logic seems to work fine, at least with internal IDE drives. My other favorite freebie is Easeus Partition Manager Home: It's professional in appearance and has all the features I generally need.
SMART (Self-Monitoring Analysis and Reporting Technology)
Today's hard drives have a self-analysis feature that keeps tabs on the drive's health. Unfortunately, although many BIOSs will relay the basic 'Hey, I'm okay (or not)' information to you when you boot the PC, Windows 7 doesn't provide a way to access the details. Several capable utilities allow you to view the information.
If you love the command line, SMART Monitoring Tools might be for you. In a DOS box, entering smartctl -a sda (or sdb, sdc, or the like) will tell you everything you need to know about your hard drive's SMART status--if you can read the sometimes overlapping information.
A better tool for viewing SMART information is Passmark's DiskCheckup. It's free, and you run it only when necessary--it doesn't have any background services sucking up CPU cycles. If you don't run your PC around the clock, this is a better approach. My absolute favorite, though, is the free version of HD Tune; it not only reports drive health (not specified as SMART but the same information nonetheless) but also tests drive performance and scans for disk errors.
If you need constant Windows monitoring for a 24/7 PC, you'll have to pay for a program such as Ariolic Software's Active Smart 2.9 ($30) or LSoft Technologies' Active Hard Disk Monitor ($6 and $15 Pro flavors).
Defragging and Optimizing
In days past (the age of FAT16 and FAT32), regularly defragging a hard drive made a noticeable difference in the speed with which it loaded applications and data--now, not as much. Even so, optimization--placing large, often-used files such as Outlook .pst files in the quickest-to-load location on your hard drive--can speed things up. (For more about the defrag debate, see 'Defragging: Why, How, and Whether.')
One great choice for optimization is an older public-domain version (1.72) of DiskTrix's excellent UltimateDefrag (though that version is now impossible to find at the vendor's site). Despite its age, it still has all the features anyone could want, including the ability to choose individual files to move for faster access.
The Smart Defrag utility has few user-configurable settings--you rely on the program's logic to automatically optimize your drive. It also shows an ad here or there, but the program works well and is smart enough to know that you can't optimize an SSD. UltraDefrag is another very capable defragging and optimizing program that you can run from a command prompt if you so desire.
Disk Usage
If you have no idea what's on your hard drive, or how much of it exists, you have a fascinating and visually appealing way to find out--Disk Space Fan. That isn't fan as in fanatic, but as in the device for moving air. In this case you browse and tunnel down into the data on your hard drive by clicking on a graphic that resembles a fan. The pro features (finding duplicates, delete, move, and so on) are enabled for 15 days; after that, you'll need to pony up $20 to do anything but view. Even without those features, however, the free version is neat. Really. Download it.
Open Port Check Tool For Mac
Any time you have hard drive errors—or even strange behavior you might not at first associate with a hard drive—Check Disk can be a lifesaver. Here’s a full guide to using the Check Disk tool that comes with every version of Windows.
What Chkdsk Does (and When to Use It)
The Check Disk utility, also known as chkdsk (since that’s the command you use to run it) scans through your entire hard drive to find and fix problems. It’s not a terribly exciting tool—and running it can take some time—but it can really help prevent bigger problems and loss of data in the long run. Chkdsk performs a couple of functions, depending on how it’s run:
- Chkdsk’s basic function is to scan the integrity of the file system and file system metadata on a disk volume and fix any logical file system errors that it finds. Such errors might include corrupt entries in a volume’s master file table (MFT), bad security descriptors associated with files, or even misaligned time stamp or file size information about individual files.
- Chkdsk can also optionally scan every sector on a disk volume looking for bad sectors. Bad sectors come in two forms: soft bad sectors, that can occur when data is written badly, and hard bad sectors that can occur because of physical damage to the disk. Chkdsk attempts to fix these problems by repairing soft bad sectors, and marking hard bad sectors so they won’t be used again.
That may all sound very technical, but don’t worry: you don’t need to understand the ins and outs of how it works to know when you should run it.
We recommend running chkdsk every few months as part of routine maintenance along with using a S.M.A.R.T. tool for drives that support it. You should also consider running it any time Windows has shut down abnormally—such as after a power loss or system crash. Sometimes Windows will automatically run a scan during startup, but most often you’ll have to do it yourself. Even if you’re just having strange problems with apps not loading or crashing that you haven’t been able to resolve another way, you might consider checking the disk.
For example: I once had a problem where Outlook suddenly started crashing on me shortly after loading. After a lot of troubleshooting, a chkdsk scan revealed I had bad sectors where my Outlook data file was stored. Fortunately, chkdsk was able to recover the sectors in my case, and everything went back to normal afterward.
If chkdsk does encounter problems—especially hard bad sectors—that it can’t repair, data can become unusable. It’s not very likely, but it can happen. For that reason, you should always make sure you have a good backup routine in place and back up your PC before running chkdsk.
The chkdsk tool works pretty much the same in all versions of Windows. We’ll be working with Windows 10 in this article, so the screens may look slightly different if you’re using Windows 7 or 8, but chkdsk performs the same, and we’ll point out where any procedures differ. We’ll also talk about running it from the Command Prompt, in cases where you can’t even boot into Windows.
How to Check a Disk from Windows
Running the Check Disk tool from the Windows desktop is easy. In File Explorer, right-click the drive you want to check, and then choose “Properties.”
In the properties window, switch to the “Tools” tab and then click the “Check” button. In Windows 7, the button is named “Check now.”
In Windows 8 and 10, Windows may inform you that it hasn’t found any errors on the drive. You can still perform a manual scan by clicking “Scan drive.” This will first perform a scan without attempting any repairs, so it will not restart your PC at this point. If the quick disk scan reveals any problems, Windows will present that option to you. If you want to force it, though, you’ll have to use the command prompt to run chkdsk—something we’ll be covering a bit later in the article.
After Windows scans your drive, if no errors were found, you can just click “Close.”
In Windows 7, when you click the “Check now” button, you’ll see a dialog that lets you choose a couple of extra options—namely whether you also want to automatically fix file system errors and scan for bad sectors. If you want to perform the most thorough disk check, go ahead and select both options and then click “Start.” Just be aware that if you add a sector scan to the mix, checking the disk can take quite a while. It may be something you want to do when you don’t need your computer for a few hours.
If you elect to fix file system errors or scan for bad sectors, Windows won’t be able to perform a scan while the disk is in use. If that happens, you’ll have the option to cancel the scan or schedule a disk check to happen the next time you restart Windows.
How to Check Up On or Cancel a Scheduled Disk Check
If you’re not sure whether a disk check is scheduled for your next restart, it’s easy enough to check at the Command Prompt. You’ll need to run Command Prompt with administrative privileges. Press Start and then type “command prompt.” Right-click the result and then choose “Run as administrator.”
At the prompt, type the following command—substituting the drive letter if necessary.
If you have scheduled a manual check of the drive, you’ll see a message to that effect.
If Windows has scheduled an automatic check of the drive, you’ll see a message letting you know that the volume is dirty, which just means it’s been flagged with potential errors. This serves as indication that Windows will run a check the next time it starts. If no automatic scan is scheduled, you’ll just see a message letting you know that the volume is not dirty.
If a disk check is scheduled for the next time you start Windows, but have decided you don’t want the check to happen, you can cancel the check by typing the following command:
Itool For Mac
You won’t get any kind of feedback that the scan has been cancelled, but it will have been. This command actually excludes the drive from the chkdsk command for the next start. If you do restart to find that a scan has been scheduled, Windows is also kind enough to provide you with about ten seconds to skip the scan if you want to.
How to Use the ChkDsk Command at the Command Prompt
If you’re willing to use the Command Prompt (or you have to because Windows won’t boot properly), you can exert a little more control over the disk checking process. Plus, if you’re using Windows 8 or 10, it’s the only way to force automatic fixing or bad sector scanning into the mix. Open up the Command Prompt with administrative privileges by hitting Windows+X and selecting “Command Prompt (Admin).” You’ll be using the chkdsk command. The command supports a number of optional switches, but we’re mostly concerned with two of them: /f and /r .
If you just use the chkdsk command by itself, it will scan your drive in read-only mode, reporting errors but not attempting to repair them. For this reason, it can usually run without having to restart your PC.
If you want chkdsk to attempt to repair logical file system errors during the scan, add the /f switch. Note that if the drive has files that are in use (and it probably will), you’ll be asked to schedule a scan for the next restart.
If you want chkdsk to scan for bad sectors as well, you’ll use the /r switch. When you use the /r switch, the /f switch is implied, meaning that chkdsk will scan for both logical errors and bad sectors. But while it’s not really necessary, it also won’t hurt anything if you throw both the /r and /f switches on the command at the same time.
Running chkdsk /r gives you the most thorough scan you can perform on a volume, and if you have some time to spare for the sector check, we highly recommend running it at least periodically.
There are, of course, other parameters you can use with chkdsk . So, for the sake of completeness—and your geeky enjoyment—here they are:

Hopefully, Chkdsk will fix whatever hard drive problems you may have, and you can go back to using your computer normally.
