 Hello everybody! In today's video, I'm going to show you a few good programs to help you test a hard disk and fix any errors they can find. If you need to recover deleted data, view or restore removed browsing history, Hetman software products will help you. Follow the link in the description, download the necessary program for free, install it and analyze the disk. The utility will show you the data you can recover, so you will be able to view it or get it back. In our channel and blog, you will find solutions to any problem, from installing an operating system or configuring it, to fixing possible bugs and errors or optimizing mobile gadgets. Our specialists will answer any questions you ask in your comments under the videos or articles. Most old AGGs do experience certain errors or contain the so-called bad blocks, which are in fact unreadable sectors. Having bad blocks means you are bound to face some sort of negative consequences sooner or later. It's only a matter of time before you are going to lose important data. To prevent that misfortune, it is recommended to test hard disks for bad blocks regularly. There are tools that can help you examine a hard disk and even fix the blocks that have gone bad over time. Any Windows operating system contains an integrated utility for checking hard drives for errors. Unsurprisingly, it is called CheckDisk. But it isn't actually intended for disk diagnostics and testing. That is why I'll be talking about other, more effective tools to test a hard disk and fix possible issues. So let's begin. For starters, we have HDD Regenerator. It's a professional tool for disk diagnostics, scanning and fixing hard disk errors. HDD Regenerator can both detect errors, problems and bad blocks and repair them. In other words, you can use it as a tool to restore damage to hard disk sectors. HDD Regenerator can also be used as a tool for recovering damaged data. If the computer can't read some data or if the hard disk is detected but is not displayed in this DC window, this tool can help you bypass the damaged clusters and still read the faulty files. The program also features a special test for disk operability, while SmartData adds more information. HDD Regenerator includes all the tools required to check a hard disk and repair any errors. It supports FAT and NTFS file systems. It offers detailed information on the hard disk's health and performance. And it can create a bootable regenerating USB drive, CD or DVD. In addition, it features a pre-scan mode, a quick scan of the disk surface and real-time disk monitoring. After our channel, free detailed video guide on using this tool, we're going to help us link below. The next one on the list is Windows Drive Fitness Test. Windows Drive Fitness Test, WinDFT for short, is one more free diagnostic utility for hard disks of any type, brought to you by a well-known hard disk manufacturer Western Digital. Earlier, it was introduced by Hitachi. However, the tool is good to test any disks, not only those produced by Western Digital or Hitachi. It includes not only several disk scan functions, but also options for Smart Attributes Preview and Disk Cleanup. Though WinDFT is designed to work in a Windows environment, it cannot scan or test the disk containing the operating system. By way of compensation for that, it supports work with external hard disks and other USB media. The main menu displays only supported drives and brief information on them, such as model name, serial number, firmware, capacity, and status. Double-click on a disk to see its smart status. Choose between Quick Test or Extended Test. It can run the test for one or even several disks at the same time. By pressing the Utilities button, you can see an advanced menu that opens in a dedicated window. There is a number of extra functions to choose from – Erase MBR, Erase Disk, Short Test, Long Test, and so on. If you can't boot from the system disk, WinDFT can run as live CD. An important feature in terms of subsequent data recovery is that this tool tests the disk without overwriting data. Another utility in today's review is C Tools for Windows by CGate. It is a free tool for disk diagnostics and error correction, as well as for testing disk performance. It can help you detect any issues your disk might have before you will be forced to contact a service center. Unfortunately, this program has only limited product compatibility. Here is a brief list of problems it can detect. Damage to the final system. Bad blocks, read errors, driver errors, and system failures. Incompatible hardware. MBR issues, presence of viruses, key loggers, and other malware. To start work, select the test and run it. When it's over, you will see a detailed report. If the hard disk completed the test successfully, you will see pus. And if things are not so fine, you will see fail. Another thing to remember is that testing a hard disk can take up to four hours. So to save your time, you can choose from three options. CGate C Tools can scan hard disks for bad sectors and repair them. In the course of repairing, the tool either tries to restore bad blocks or zero-fill them. This method makes the operating system ignore bad blocks during read or write operations. HDD Health Another free utility for testing hard disks and monitoring their health. It examines the hard disks for errors and calculates a kind of a health index to predict its behavior in the future. It can work with both HDDs and SSDs. This is the information you can see in its main window. Data, firmware, current temperature, general status, as well as other attributes in the extended information window. As well as other diagnostics utilities, HDD Health reads the smart data, which gives you a general idea of the disk status and performance. Disk programs contain no other components for detecting errors and checking the disk for bad blocks. Summing up, it is good for quick diagnostics unless your disk is in a critical condition. You can download the tool from the official website. You can find the link below. HDD Scan is a free diagnostics utility for hard disks which can read smart attributes, check the SSD status and examine a number of other things. After a disk test, you will see a log file containing detailed information on its condition. HDD Scan supports various storage devices – rate arrays, hard disks with ID and SATA interfaces, SSDs as well as USB drives. This utility helps you check the disk for errors that integrated Windows tools will never show you. I mean physical and logical bad blocks or bad sectors, whatever you call them. You can choose between several types of tests – verify, read, butterfly, erase. It also features temperature monitoring for all hard disks connected to your computer and it can export any data into a configurable report file. Download link below. As I was saying at the beginning of this video, Windows also has a disk checking utility of its own – check disk. Windows 10 and Windows 8 already have the feature of checking hard disks for errors automatically, but you can do it manually as well. Open properties for a hard disk, select the tab tools and click on check. Alternatively, you can open command prompt and run the check disk command. However, this utility can help you find and fix only some basic issues. Unfortunately, it is not intended to search all kinds of errors and it can't help you with diagnosing an HDD at all. However, with check disks, you can fix errors on your storage devices and even repair some damaged partitions. As a result, such partitions will be marked in a special way so other tools will ignore them when reading or writing data. Download link below to watch a detailed video guide on checking and fixing a hard disk with this utility. Summing up I'd like to say that this is only a brief list of tools for testing hard disks, as I selected only a few popular applications. You can check the description for this video and find links to many other free utilities like disk checkup, GSmart control, Samsung HUTil, BARTstuffTest, HDTune, ASus Drive Check, Macro Rate Disk Scanner, Aureolic Disk Scanner and the famous Victoria.
