Advanced drive-health diagnostic utility.


DriveDx is an advanced drive-health diagnostic and monitoring utility. Save yourself from data loss and downtime that is associated with unexpected drive failures. Don't worry about losing your important data, music, and photographs. Unlike most drive utilities, DriveDx not only monitors the drive’s built-in S.M.A.R.T. status, but also analyzes the changes of all drive health indicators that are closely related to SSD or HDD failures (like SSD wear out / endurance, reallocated bad sectors, offline bad sectors, pending sectors, I/O errors, and more) and alerts the user immediately if anything goes wrong. Our drive-health diagnostic algorithms are based on recent research in the field. The application provides access to all sufficient drive-diagnostic data to satisfy any system administrator. DriveDx is the first utility of its kind to have a real user-friendly, Mac-style interface.

When evaluating the state of various drives, DriveDx can use different (specialized) heuristic algorithms, depending on the drive model and even its firmware version. One of the key advantages of the software is that the state of HDD and SSD drives is assessed using different algorithms (DriveDx has separate sets of rules and algorithms for HDD and SSD drives), since many state indicators of HDD drives are not applicable or make no sense in the case of an SSD drive.

  • Support of modern SSDs and HDDs
  • SSD lifetime left indicator
  • Different routines for SSD and HDD health evaluation
  • Real-time SSD and HDD health status monitoring
  • User friendly and intuitive UI
  • Pre-failure state early detection - DriveDx supports 4 drive health statuses: Ok, Warning, Failing (pre-failure) and Failed. (Most of drive utilities support only 2: "Ok" and "Failed")
  • Drive failure prediction based on health indicators that are closely related to SSD or HDD failures
  • Interactive hints and descriptions for all health indicators (SMART attributes)
  • Multi-tier warning system that will inform the user about deviations from the normal state of drive attributes
  • Diagnostic Knowledge Base online auto-updating
  • Drive overall health rating
  • Drive overall performance rating (if drive supports this subset of indicators)
  • I/O errors monitoring
  • Drive free space monitoring
  • Support of drive short and full (extended) self-tests
  • Save drive(s) health report to file
  • Automatic drive health reports by email (automatic email reports)
  • Human-readable drive health indicators (attributes) representation
  • Drive temperature monitoring
  • History-based drive health evaluation
  • S.M.A.R.T. error log
  • Growl notifications
  • Retina displays support

Well TJX, I'll give 5 stars for you. I agree with you that this is the "best, most excellent" drive utility I have used. And I also have tried them all. Far better than SmartUtility and SmartReporter. I especially wanted the ability to check external USB drives. Great for my purposes.

It saved my data when it flagged a drive was on its way out. I backed up my stuff and ordered in a new drive, and re-purposed my old drive as an external. Two months later it died.

It's a pretty good utility for getting drive stats and status. However support has been nonexistent. I have requested assistance with a DriveDX issue from the developer 3 times since January 2nd 2019. That's 1 request with 2 follow ups repeating my request, However my requests for assistance have been completely ignored. No response from them, zip, zilch. This is after spending $200 on business licenses for DriveDx. I can't recommend this software to anyone if you think technical support response will be important to you. I'll update my review if they decide that the promise they make of patron technical support is important for them to fulfill. I must say I don't run into many lazy software developers. Very disappointed!

In the option "More apps" also stands "Stellar Drive Defrag" as app created by BinaryFruit.
This is not true, BinaryFruit only has created "DriveDx" and nothing else.

This information is false and has to be refitted!!

If you want to know the status of any drive at any moment then you must have this app! It even has excellent test features built into it. This is one of the very 1st apps that can look at any SSD no matter the format and tell you what the drives status is. It is completely non-intrusive. Support is excellent. Recent updates make it even more excellent! Works great in Mojave!

Can anyone tell me whether DriveDX gives diagnostic information for a SSD which is part of a fusion drive?

This is a response to @frans-3 below who asked why one app can report 90% health, and another 85%, but also in general to anyone using utilities that interpret SMART data, and to be careful what conclusions you draw. SMART data is just raw data; the industry and drive makers have (purposefully) left open and undocumented, many of the attributes reported, so they are open to interpretation by both drive manufacturers, and by software like Drive X that interpret the data. Seagate may choose to report one attribute differently than how Western Digital chooses too, for example. The SMART specs are often vendor specific, although some over time have come to a general agreement about what it is reporting, but only as it relates to what raw data is reporting, NOT what it means in terms of predicting future health. Kind of like a car; 4 people may report that they hear a 'funny' noise when the engine runs, they all agree and report there is 'a noise'. They may disagree what it means or predicts, and then the reality might be the engine could fail tomorrow, or it's nothing, and the engine is fine, it's just a noise but does not effect performance. To make it even more ambiguous, the SMART spec was developed when hard drives were mechanical; it hasn't been updated by the industry since 2011. with SSDs,, even vendors disagree as to what certain attributes mean or are supposed to report when it comes to SSDs, where some of those attributes don't even make sense. For example, a 'bad sector' on a physical mechanical drive has a real physical location, that is fixed (platter 1, side 2, block 30, sector 5, etc). On a SSD, sectors can be relative, the SSD controller reallocates sectors and blocks all the time, a 'sector' number as the operating system thinks of a sector number, doesn't necessarily correlate to the same physical location on a memory chip at any given time, or over time. The concept of 'sectors' and 'blocks' is a hold over from mechanical drives, it is useful to continue to use such terms so that backward compatibility with old BIOS's, drive software and Operating systems is maintained, but 'under the hood', hidden from the operating system, it's not directly identical to how rotational drives managed such things. I'm not saying these diagnostics are not useful, but you have to take with a grain of salt, especially with SSDs, because it is all up to the drive maker's interpretation of WHAT to report and WHAT is BEING reported, and up to the software vendor of the diagnostic program, to interpret what the data means, and make predictions from it. Percentage 'health' reports and predictions, are at best generalized and open to interpretation, at worse, potentially misleading. In your example, you have to ask, what does '90%' actually mean, according to DriveDX? Does it mean, 10% of the sectors are bad? Does it mean out of 50 SMART attributes measured, 90% fell in a 'good' range, and 10% fell within a 'bad' range? Is each attribute weighed equally? (obviously some are probably more significant than others, are they given more weight?) Is it a probability, like 90% chance of rain tomorrow? Like 90% chance of failure? When? Tomorrow? A year from now? Over a length of time? What length of time? If it reports 90% today, and 85% a month from now, does it mean you run out and buy a new drive? If someone is using these drives in a mission critical environment (24/7, minimal down time) would he/she take the extreme and say anything less than 100% healthy is unacceptable? In reality, s/he would be replacing drives CONSTANTLY if they took that position, so it begs the question, so if not 100%, then when if at all? Replace at 90%? 85%? 75%? If your auto repair guy said your car was '90%' healthy, what would that mean? I think you see the point.

DriveDX give me a health for my iMac SSD (part of Fusiondrive) of 90%, SSD reporter however gives me a health of 81%! How can this be???
