What should you do if your hard drive suddenly stops working as expected? How can you figure out whether it’s a simple file system error, a failing sector, or something more serious? And, given the amount of software out there claiming to be the best hard disk repair tool, how can you tell which ones are genuinely reliable?
Rest assured that some software solutions do work and can address many hard drive problems. While none can fix severe physical damage, the right tools can repair corrupted file systems, recover lost partitions, restore access to unbootable drives, repair bad sectors, and even help safeguard your data for the future.
10 Best Hard Disk Repair Software Tools For Monitoring and Recovery
Our list below includes options that are suited for both Windows and macOS, so you can use them to analyze, avoid, and solve virtually all common hard drive issues.
1. Disk Drill – Best for Hard Drive Data Recovery

Disk Drill is a professional and user-friendly hard drive recovery tool designed to recover lost or deleted data from even the most problematic drives. It can restore lost partitions, recover files from corrupted, unbootable, crashed, or RAW drives, and handle RAID arrays or NAS devices.
It uses an all-in-one scan that utilizes metadata and signature-based scanning to uncover as much data on your problematic drive as it can, and includes a one-of-its-kind Advanced Camera Recovery (ACR) module for the reconstruction of fragmented video files from damaged media. You can even add virtual drives and disk images, allowing for recovery without the physical drive. And, it supports cross-platform scanning across Windows and macOS.
Beyond recovery, Disk Drill comes with some free features to protect and manage your drives. It includes active S.M.A.R.T. monitoring, which will run in the background and alert you to anticipated failures. The advanced byte-to-byte backup module uses a multipass backup algorithm to work effectively with failing drives, and visually maps out and highlights damaged sectors.

5. CrystalDiskInfo – Best Health Monitoring Tool

CrystalDiskInfo is an extremely handy disk monitoring utility that’s best used as a preventative measure rather than a last resort fix. It can read S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) data from hard disks. S.M.A.R.T. data includes things like the read error rate, seek error rate, or spin-up time. Your S.M.A.R.T. values service as an indicator that can warn you about impending failure, which makes CrystalDiskInfo almost an essential companion for everyday use.
It also allows you to set up custom alerts so you’re warned when thresholds are exceeded. Because it focuses primarily on monitoring, it doesn’t have a lot of additional features like the other solutions we’ve mentioned. That said, it does offer historical temperature graphs, AAM/APM control for turning noise and power settings, and a portable version to run without installing.
👤 User experience:
“I’d suggest that you check on your NVMe or SSD storage using Crystaldiskinfo. It’s good, I use it frequently to monitor my hard drive’s health from time to time”

Considering that the last version of SpinRite, an application for recovering lost files from magnetic data storage devices such as hard disks, was released back in 2004, you might be surprised to see it featured on this list. The reason why we decided to include it is simple: it remains the best hard drive repair tool for older computers. SpinRite works at a low level, accessing the magnetic data on the disk rather than relying on the file system. This lets it recover data from drives that are unreadable, have intermittent errors, or are failing slowly over time.
Since it runs inside a live version of FreeDOS, you can use it to scan just about any computer – even one that doesn’t work properly anymore. The tool supports not only Windows file systems but also DOS FAT, all Linux file systems, Novell, Macintosh, and more. Beyond recovery, SpinRite can detect weak sectors before they fail so you’re aware they exist. While its text-based interface may be reminiscent of Windows XP, its low-level scanning and repair capabilities make it a unique solution.

Are there Alternative DIY Solutions to Repair a Hard Disk?
Not every hard drive problem you run into will require professional repair or costly software. Before you send your drive into a lab or invest in specialized tools, there are several practical DIY steps you can try. These methods will help you address common logical errors, check hardware connections, and restore access to files, often without spending a dime. While they cannot fix serious physical damage, trying these alternatives first can save time, money, and a lot of frustration.
Run Antivirus

Many strains of malware exist on the web. Some forms of malware can mimic a hard drive failure, making files disappear or preventing your system from booting properly. The good news is that Windows comes with a capable antivirus called Windows Defender. Scan your PC with Windows Defender (or another antivirus software) and remove any potential threats.
Check and Repair Hard Disk Errors

Modern file systems are robust and reliable, but they’re not entirely immune to data-loss-related errors. Built-in tools, namely CHKDSK, can scan your drive for logical errors and fix them, helping to restore normal operation without third-party tools. For Mac users, First Aid is the equivalent of CHKDSK.
Re-Install Hard Disk Drivers and Update Firmware

Sometimes, hard disk issues are caused by outdated or faulty drivers and firmware. Reinstalling or updating your drives or firmware can resolve compatibility issues, return performance to baseline, and prevent unexpected drive failure.
Format the Disk

Formatting a hard drive can fix persistent errors and corrupted file systems by giving the disk a fresh file system. A Quick Format is usually what you need, which only erases the file references and adds a new file system. However, if you want to address bad sectors, a Full Format is what you want.
Check Physical Hard Disk Connections

Your hard drive connects to your motherboard via two cables: a power cable, for electricity, and a SATA cable, for data transfer. Loose or damaged cables can cause a wide range of issues, so a quick inspection will help to avoid unnecessary troubleshooting. External drives are a little different, and you will need to inspect the USB ports, cables, and any adapters or enclosures. If it’s still not recognized, see our guide on recovering data from external drives that are not recognized.
Connect the Hard Disk to a New Computer

If none of the above-described fixes have worked, try connecting your hard drive to a different computer. If the drive works like normal on another system, the problem is likely with your own PC rather than the drive itself. See our guide on how to recover data from an external hard drive that isn’t detected for more information.
When Should You Contact a Professional Repair Service

If the drive fails to respond and isn’t showing up in Device Manager or BIOS/UEFI, or if it’s making unusual scraping, clicking, or grinding noises, DIY methods are no longer safe or effective. In this case, you should send your drive to a data recovery professional.
Other obvious signs of impending drive failure include repeated S.M.A.R.T. errors, constant disconnections, or a lack of access, even through data recovery software. Trying to fix these issues yourself will lead to further damage and likely permanent data loss.

FAQ
It depends on the bad sectors. Soft bad sectors are logical, meaning software tools can reliably fix them. Hard bad sectors, on the other hand, are generally considered irreparable, with those that can be repaired by HDD Regenerator being the exception. Monitor your S.M.A.R.T. data. If you’re seeing concerningly high values, the drive is no longer reliable and needs to be replaced.
Absolutely. First, you should recover your data using data recovery software like Disk Drill. Once your data is recovered, you can either try repairing the drive using tools like CHKDSK, DiskGenius, or DiskWarrior, or simply format the drive since all your data is now safe.
These costs are hard to estimate, since every recovery service is different, which therefore affects the final price. However, if we had to guess, the cost of the average recovery ranges from $300 to $3000, but can definitely exceed this in special or urgent cases.
1000 times yes. A drive facing recurring errors, physical damage, or an increase in bad sectors, replacement is the best decision. DIY repairs can help temporarily, but the problems will only exacerbate and not stop until the drive fails completely.
No. Unless you can restore it with HDD Regenerator, that data is gone for good. Your drive will attempt to remap the data to a spare, healthy sector, but if this there is no telling what was stored on which sector.
