These will cross check index files on the drive and correct them as needed. Both tools focus on the filesystem level which usually is not a problem because bad sectors tend to get handled by the drive itself. Drive Genius 4 includes a comprehensive suite of utilities to check and repair your Mac’s hard disk. It also includes a real-time monitor to check for errors, fragmentation and bad blocks whenever your Mac is idle. Professional tools are the best option to defragment your Mac’s hard disk.
Scannerz finds weak sectors along with bad sectors and can be used to troubleshoot cable and system problems. Disk Warrior also rocks because it can reconstruct drive index files on a problematic drive. A few other tools (that I’m not going to name) say they can do the same thing, but I haven’t been impressed with them – kind of like comparing a Yugo to a Ferrari, if you get my drift. That clicking noise could mean a full crash is coming soon. Make sure all of your data is backed up before you do anything else. This program shows you the statistics that most modern hard drives record. Some of the stats might be a little hard to understand, but the program breaks it down into a simple Health Status meter.
- To cut it short, if you have Fujitsu hard drive, use this tool.
- Active SMART will suspend your PC automatically if the hard drive becomes too hot.
- If you get a risk of failure warning for a hard drive, it’s strongly recommended to backup the data immediately, because the chances of failure are very high.
- This saves your important data and prevents the hard drive possible failure.
- All in all, if you are looking for simple yet fully-featured software that can find any and all possible faults in your hard disk then do give HDDScan a try.
Disk Utility on Mac system also has a command line equivalent. It can offer users to perform disk check and maintenance from the terminal. Reboot Mac and hold down “Command + S” key buttons at download speccy the same time to enter the Single User Mode. In the displaying terminal window, you can type “diskutil verifyVolume ” to verify a drive on Mac. Unless 3rd party support is added, USB and Firewire drives will not be SMART capable. SMART can report a certain number of developing problems with an internal hard drive that may be critical, but they won’t get reported if they’re on USB/FireWire drives.

An occasional transient error that does not recur usually is benign. The smartmontools Web page has a number of examples of smartctl -a output showing some illustrative error log entries. The second part of the output shows the results of the health status inquiry. This is the one-line Executive Summary Report of disk health; the disk shown here has passed. If your disk health status is FAILING, back up your data immediately. The remainder of this section of the output provides information about the disk’s capabilities and the estimated time to perform short and long disk self-tests.
Disk Utility is only nearly as useful as CHKDSK in Windows. To check physical hard disk health on a Mac you either have to buy an application, or take the disk out of the mac and test it in a Windows/Linux PC.

Two free apps available in the Mac App Store are as follows. Your Mac’s hard disk must be working properly to ensure your computer’s overall system health is maintained. In general, Mac disks are extremely reliable and you’re not likely to encounter any physical problems with the drive unless it’s suffered an accident such as being dropped. In that case, the sudden motion sensor on the Mac will automatically park the disk read/write heads to minimise the chances of damage. You can turn off automatic checking of hard drives on your Mac.
Apple doesn’t actually recommend any specific defragmentation tools or even include any relevant utilities in Disk Utility. The Mac performs defragmentation automatically, but only when specific conditions are met such as the files being a certain size. Therefore, fragmentation can and still does occur and over time the problem just gets worse. It’s useful to know how fast your Mac’s disk really is, in order to compare it with others and also to check whether it’s performing consistently over time. It’s also interesting to perform the same tests on a regular hard disk and an SSD, because the difference can be quite staggering. The most convenient way to benchmark your disk speed is to download an application that measures raw read/write speeds.
“Bonnie++” is one, and a whole suite of hard drive diagnostic tools is available on the Ultimate Boot CD as described here. Basically they have a degree of self-test capability that the user can access to help determine the health and life expectancy of a hard disk drive. Modern hard disk drives incorporate Self-Monitoring Analysis and Recording Technology, aka SMART. Most of these tools allow you to compare your SSD’s speed to the industry standards. If you notice that yours is running unreasonably slow, it could be a sign that it’s time to SSD health check. SMART (Self-Monitoring, Analysis and Reporting Technology) is a useful tool which is likely built into your hard drives that you already use on your server. ClearBOX typically uses SMART hard drives and a diagnosis of your drives using this technology is often a requirement to receive an RMA.
