OcCT
1.
It also monitors temperatures, voltages, fan speed, as well as memory usage and frame rate (FPS) (3D test). It has the most accurate error detection algorithm for CPU and GPU.
Even though components are currently well protected from overheating, OCCT includes another layer of safety by allowing you to set a maximum temperature limit. OCCT's CPU test is the most advanced out there.
Capable of detecting stability issues in seconds, it can perform per-core testing and allow you to adjust the instruction set used and data size.
Victoria HDD - SSD
2.
You can examine your disks for various problems and if any are found then the application has the ability to repair them. It can analyze and display details about your storage media, including disk size, serial number, and more. The application may redirect, restore, ignore or delete the data in the sectors that have errors or delete the data and correct it.
A powerful HDD surface scanner is built into the program, which allows you to diagnose the drive for bad areas, defects and interface errors. It is able to test almost all discs regardless of their type.
A feature of the scanner is the use of special algorithms for automatic adjustment of time limits and block size, which allows you to efficiently scan both slow and fast disks.
The graph is based on 188 points, evenly distributed over the tested volume of the drive. The result is visually and numerically identical to a full 4-hour scan, except for finding defects.
It is used to study known good drives to measure the main parameters: speed at the beginning and end, access time, behavior in different block sizes, as well as to compare different devices in terms of technical characteristics. Charts can be saved to files and loaded back into the program. (The website is in Russian language)
Precise CPU Stress
3.
The software constantly shows the stress levels of the fundamental resources of the computer (CPU, RAM, Disk) for the last moment with a resolution of seconds. The current size of the paging file. sys is displayed at the bottom of the window. It supports Windows 7/8/10 and 11 but only the 64 bit version.
Modern software offers you an easy way to check your computer's hard drives for errors. It displays information about your drives in real time and monitors your hard drive values throughout its operation and notifies you immediately after any errors that may occur, so you will know immediately if something is wrong with your hard drive.
CheckDrive 2023
4.
To check if a hard drive has errors, run the application and you'll see a question mark next to each drive, which means the drive hasn't been checked yet. Now click on the Check button and if everything goes well you will see the indicator indicating that your disk has no problem. It will also work for SSD drives. To use the application you must register.
MemTest86
5.
MemTest86 however, is a great diagnostic that can help diagnose faulty RAM (or rule it out as the cause of system instability). Therefore it is often used by PC repair shops, overclockers and computer manufacturers. It boots from a USB flash drive or CD and checks the RAM on your computer for errors using a series of comprehensive algorithms and test patterns
Boot Repair Disk
6.
The problem becomes even more acute when the user has not foreseen to make regular backups of the files on his computer and here of course we are talking about the absolute "disaster" especially if our files include useful documents, photos, music and in general any of our other files. necessary.
The truth is that in order to be able to successfully deal with such failures in these situations one must have some relevant experience. However, there are some applications that can help us identify the problem and try to solve it and some others that undertake to solve our problem automatically.
The program that we will present today belongs to the second category and it is nothing more than a live CD from which we will boot our computer and it will automatically recognize the problem and try to solve it.
Windows Repair Toolbox

Before you start download and install the program, and Rufus (we will need to copy the application DVD to a USB stick to start from).
All In One - System Rescue Toolkit
10.
While we can't guarantee that you'll fix the specific problem you may be experiencing, this may be the first step before you need to call a technician. You don't need to be an expert to use it because all the repair work is done automatically.
All you will need is to simply run it and wait until the check and repair process is completed. The repair steps include checking basic and minor functions in Windows and are as follows: CPU / Cooling test, memory test, hard disk function test, Windows Security Center test, virus scan, network function test and system restore, file check system, disk cleanup and Defrag.
In addition to the lite version you can download the full technician version aimed at advanced users through which you can literally do almost everything. For this purpose you will need to download the Live CD of the application and burn it to a CD through which you will Boot, however, the main menu with the necessary tools can also be run from windows.
Which in particular, if you have WINDOWS 10 or 11 after downloading the ISO of the Live distribution right click on it and press mount. Alternatively, for even better results, unzip the contents of the ISO to a folder and run it from there.
In the folder that will open right click on the AiO-SRT file and run it with administrator rights. To download the application click on All in One - System Rescue Toolkit and download, select technician version and from the download option, select the location from where you will download the application.
Dead pixel tester
11.
However, please note that this tool does not provide a 100% success rate. Start by pressing the first START selecting the colors one by one and observe where the problem is on your screen (to exit press ESC), now in case you find a problematic Pixel press the second START and move the window with the colors that flash to the spot with the problematic Pixel.
Let it work for some time, now if everything went well the problem will be fixed. For the application to work properly, run it with administrator rights.
Hard Disk Validator
12.
What is a bad sector? As hard drives are known to write data in block units (sectors), every time a hard drive updates a sector, it also updates a checksum (stored immediately after the sector data).
When a sector is read from your hard drive, it is expected that the sector checksum will match the sector data, if it does not, then most likely bad sectors have been created.
The appearance of bad sectors can come from either a power outage during recording or from some other malfunction of the hard disk for some other reason such as falling, mechanical damage and others.
The question that arises is this: Can bad sectors be repaired? NOT always, however, if the data stored in the sector is simply invalid, but your hard drive is working properly, you can repair the bad sectors that have been created.
However, before you start you should first see if your disk has bad sectors. For this purpose, run the HardDisk Validator application, select Read and press Start to start the diagnosis.
If you see that there are bad sectors which you found to be created recently, for example after some power failure run the application and select "Read + Wipe Damaged + Read" is the fastest way to eliminate the bad sectors and avoid any problem with software that does not respond well to bad domains. If something appears to be wrong with the drive, it is best to back up the data and use the "Write + Verify" test, which will erase all data on the drive.
CAUTION : If you use a single disk to boot your operating system you can run the scan to see if your hard disk has bad sectors, however, it is recommended that you avoid trying to repair it if it is the one that hosts your current operating system . In this case, what you can do is disconnect your hard drive and connect it as a second one, to another computer and run the program there.
Possibilities of the application
- Read: It will scan the entire surface of the hard disk to detect bad sectors.
- Read + Wipe Damaged + Read: Scans the entire surface of the hard drive to find bad sectors, if bad sectors are found, they will be replaced and re-read to make sure they were successful this time around.
- Read + Write + Verify + Restore: The program will write a test template to disk, verify that the template was successfully written, and then restore the original data.
- Write + Verify: The program will write a test template to disk and verify that the pattern was successfully written. (original data will be lost).

16.
Audio measurement diagnostic program that performs various tests on the performance of sound cards, in this way we are given the opportunity to measure, evaluate and compare the performance of sound cards. You may need to run it with administrator rights to install it.
To test audio devices, the program uses frequency analysis algorithms. It can perform both playback and recording tests for the computer's sound card or other audio equipment, thus detecting possible output distortions. After all tests are completed, you can see the values of all selected parameters in the "test results" window.
One advantage is that you can load test results for multiple devices, which allows you to compare them. Additionally, each set of results can be viewed and analyzed using spectral graphs.
SystemRescueCd
17.
It aims to provide an easy way to perform administrative tasks on your computer, such as creating and editing your hard disk partitions. It comes with a large number of parted programs, partimage, fstools, and basic tools (editors, midnight commander, network tools).
It can be used on both Linux and Windows computers and requires no installation as it can be booted from a CD, DVD or USB stick, but can still be installed on your hard drive if you wish. The kernel supports all popular file systems (ext2/ext3/ext4, reiserfs, btrfs, xfs, JFS, vfat, ntfs), as well as network file systems (samba and nfs).
GFX Memory
18.
A very useful tool that will help us see the capabilities of our computer's RAM memory and make a comparative evaluation between different types of memory as well as the difference in speed or not in case we want to overclock our computer. However, we should note that the results should only be compared on the same computer running the same version of the GFX Memory Speed Benchmark.
Ultimate Boot CD
19.
The collection is extensive and includes CPU and RAM testing tools, evaluation tools, hardware identification, system information, benchmarks, BIOS tools, hard drive diagnostics, hard drive management software, erasing and cloning programs , partition as well as boot managers, network tools and various Linux and DOS boot disks.
The CD also includes a program to make a copy to a USB stick so you can use it even on computers without built-in CD drives.
Macrorit Disk Scanner
20.
"Bad sectors" are a sign that our hard drive is coming to the end of its life and that it is no longer safe to store our data, which sooner or later will lead to significant or even complete loss of hard drive data where found the problems which means that we will have to replace him as soon as possible.
BatteryMon, is a battery monitoring application. It is designed as an easy-to-use application for Windows and allows users to monitor the performance of laptop batteries and power supplies (UPS).
BatteryMon
21.
Graphically you can see your battery's charge-discharge frequency, diagnose problem cells, compare and measure your batteries' performance against expected discharge values, see your batteries' critical discharge point, record the performance of a battery for later reference, refer to the status of each individual battery when multiple batteries are used.
Batteries, given their chemical nature, are prone to wear, corrosion, leakage and outright failure due to events such as short circuits. Given their tendency to fail and degrade over time, it is important to be able to detect and monitor their performance.
With BatteryMon, monitoring the battery status of your laptop or UPS has never been easier. Finally, clicking your mouse on the graph minimizes the application and it now appears on your desktop as a bar.
SeaTools
22.
It includes several tests to determine the proper functioning of the disks and will inform you by describing the complete technical profile of your disk as well as its state of health.
You can test HD with SATA, USB, 1394, ATA (PATA/IDE) and SCSI connection. It will work for all hard drives, but also for new technology SSD drives. The application is available for free and is from Seagate, but it can still work with drives regardless of their manufacturer.
It is a useful testing tool to eliminate the hard disk drive as the source or physical cause of a system problem. A drive can be perfectly healthy but have corrupted data.
If this is the case, run the chkdsk function. SeaTools runs on Microsoft Windows and Linux operating systems and provides the following features to manage them and displays drive information such as, model, capacity, disk usage, temperature and lifetime, monitors the health of drives, displays the attribute and Self-monitoring Analysis and Reporting Technology (SMART) identification information, maintains an event log, performs configuration tasks such as log export and firmware updates.
As we said above, SeaTools supports all drives however, not all its features are supported for non-Seagate drives.
When we start the "Small Drive Self Test" (DST), most drives will run a detailed diagnostic routine built into the hard drive's firmware.
DST is completely safe for data. The "Short Drive Self-Test" is sufficient for most cases. The "Short Generic" test is similar and tests different areas of the unit.
If you need a more comprehensive test, consider running "Long Generic," which reads every sector on the drive. Long tests, however, will take time to complete.
Because long tests read every sector on the drive, the time required will depend on the speed and capacity of the drive. An apparent lack of activity often gives the impression that the drive or software has stopped responding.
"Fix All" tests provide the ability to resolve LBA (bad sectors) problems. There are two options with the "Fix All" tests, "Fast" and "Long". Make sure you back up all your data before running any of the Fix All tests.
When SeaTools reallocates these problem sectors, the actual data in a particular sector is unreadable and already lost. If the drive isn't full of data, it's very likely that the problem sector is empty of data anyway.
"Fix All Fast" uses the drive's activity logs to identify suspicious sectors that may or may not be problematic. "Fix All Long" does a sequential scan of the media and discovers any problematic sectors and attempts to reallocate them along the way.
23.
DiskMark
DiskMark is a free application for Windows that allows you to measure the read and write speed of your hard drive. It uses various methods to evaluate the performance of your drive and provides you with detailed information about speed, responsiveness, and overall performance.
One of the main advantages of DiskMark is its ease of use. After installation, you simply run the application and select the hard drive you want to evaluate. The application will then start the measurement process and present you with the results in an understandable format, usually with graphs and charts.
Another advantage of DiskMark is the accuracy of its measurements. The application uses multiple methods to ensure reliable results and avoid distortions. This is especially important when trying to evaluate the performance of your hard drive and identify potential problems.
Additionally, it provides customization options that allow you to adjust the measurement settings according to your needs. You can choose the size of the files to be used during the measurements, as well as the number of repetitions. This allows you to customize the measurements to your needs and get even more accurate results.
Before starting, specify the storage medium you want to measure, specify the values you will see in the small window that will open, and press Start.

Fake Flash Test
The phenomenon of "fakeflash" has become increasingly widespread in recent years. Although many people have not heard of it, the truth is that we should be careful when buying SD or USB flash drives as they may be counterfeit.
"Fakeflash" refers to flash memory that is sold as genuine, but is actually counterfeit. These counterfeit products usually have a lower storage capacity than what is stated on the packaging. This means that you may buy a 64GB flash memory, but it may actually only have 8GB or even less.
Using counterfeit flash drives can have negative effects on the performance and security of our data. When we buy a flash drive, we usually do so to store important files, such as photos, videos, or documents. However, if the flash drive does not have the expected capacity, we may not be able to store all our files or lose data that we have already stored.
Additionally, counterfeit flash drives can be prone to damage and failure. If we use a counterfeit flash drive to store important data, there is a greater risk of losing it due to an unexpected failure.
Many USB flash drives and SD cards are sold on auction sites at very cheap prices. They are usually high capacity (16, 32 GB, 64 GB or 128 GB, even more) ( in the photo you see a USB that was purchased with a capacity of 4GB and in reality it is not even 800 MB) and usually come from the Far East.
The counterfeit product is usually made from a poor quality or defective smaller flash memory chip (and possibly a second-rate "reject" memory chip.
To detect these fake flash drives and memory cards, there is a great application that we can use called FakeFlashTest. It is a free software that can check the real capacity of a flash drive or memory card.
Using it is very simple. You just need to download the software and then run it on your computer. Then you connect the flash drive or memory card you want to check and FakeFlashTest will take over the control. In a few minutes, it will give you a report on the real capacity of the device.
This is a tool developed by Steve Si to help users identify counterfeit SD cards and flash drives. This version provides a fast and reliable method for identifying counterfeit products and diagnosing memory quality.
It performs a series of checks to detect counterfeit SD cards and flash drives. These checks include verifying memory capacity, detecting bad memory sectors, and analyzing data transfer speed. In this way, the tool can help you protect your data from loss and corruption.

AFTER CHECKING THE USB
You may find that your memory device was "working" before you used FFT, but now you can't reformat it.
FFT only reads and writes the normal, standard sectors on your memory device. It does nothing 'special' to the device.
The most common reason for reformatting failure is that you are trying to format it as an NTFS volume.
The reason it worked when you first got it is usually because it was originally formatted as FAT32.
If you cannot partition/format the USB drive at all, or if Windows/Linux now doesn't even detect the USB drive, then your device is now DEAD! This often happens when sector writes are made on fake USB drives to sectors that don't actually exist near the end of the long fake drive.
For example, the USB drive controller firmware is called to write to a sector at 128 GB, but there is only 16 GB of flash memory and the firmware/controller gets completely confused (because it has been hacked).
How to avoid counterfeit flash memory?
- We only buy from trusted sellers. We choose well-known stores or reliable websites to purchase flash memory.
- We check the packaging. We look for any indication that the product is genuine, such as an authentic logo or seal.
- We confirm the capacity. We can use special testing programs to verify the actual capacity of the flash memory.
- We read reviews and ratings. Before buying a flash drive, we read the experiences of other buyers to be sure of the quality of the product.
