USB Disk Security Is a free application designed to provide complete protection against all kinds of malware spread via removable USB drives. The application works with external hard drives, memory cards, digital cameras, flash drives, as well as with other devices that can be connected via the USB connector. Disk Security is based on a special technology for detecting threats; As an anti-virus program, the utility is able to work in stealth mode, only letting it know about its existence only in case of detection of malware.
Basically, the infection of a personal computer with viruses occurs at the time of using the global Internet, a little less often it happens during the installation of a dubious or unverified program. An infected file can also enter the PC through the most ordinary flash drive.
When an infected flash drive is connected to a personal computer, malicious software penetrates the hard drive, and most importantly, it happens so quickly that the installed antivirus programs do not always have time to react in time. Especially for such cases, it is necessary to use programs that can easily cope with this type of threat. Today Disk Security is one of the best programs to protect against infected files spread via USB drives.
When viruses are detected, the application, depending on the settings, will remove or block them, thereby preventing them from starting automatically. In addition, the utility is able to restore the system after it has been infected with malware, clear the hard drive of temporary files, prohibit copying files from the computer's hard drive, check URLs, completely block USB ports, manage startup, and force scan hard drives.
The program is equipped with a convenient and simple user interface in Russian. The control panel is located on the left side of the working window and consists of seven main items. The following sections deserve special attention: data protection, scanning and USB shield.
The last section is responsible for displaying a complete report on all detected threats. You also need to take into account that the utility automatically removes any malicious application by default. So in order to avoid deleting important documents, it is better to disable this option, for example, after deleting the boot file, your USB drive will not be able to start. Once disabled, Disk Security will act as follows - it will automatically move the infected file to quarantine or simply mark it.
In addition to the tools for automatic checking of flash media, the "Scanning" section is equipped with a vaccination function. Vaccination can be carried out both on removable media and on the personal computer itself. In this case, a special file is created on a USB flash drive or hard drive, which prohibits the launch of some malicious applications. Vaccination can be turned off if desired.
The "Data Protection" section is able to provide devices with higher protection, for example, you can prohibit the movement of data from a computer to a memory card or even block access to a PC via a USB port. To close access, you will need to restart the computer, only after that the settings will take effect.
Main features of USB Disk Security:
- Performs a more thorough scan of external drives. If malware is detected, they are either deleted or quarantined.
- The presence of a resident antivirus scanner that is triggered when a new USB drive is connected. Without making changes to the settings, the infected files will be automatically deleted.

USB Disk Security is a simple and effective program for providing complete protection against malware spread via removable media.
And again, return the ability to use it for writing and reading.
In this case, you will have to sacrifice data, which then, perhaps, cannot be restored.
But the alternative to using these applications is both non-working and lack of information.
Diagnosing the problem
The main signs that the flash drive needs repair are:
- Issuance of messages about the protection of USB-media from copying or about an unidentified device;
- The impossibility of determining the drive by any computer;
- Lack of disks in the list;
- Inability to read (and, of course, write) information;
- Negative result when trying to recover or format.
Sometimes the problem may lie in the USB connector or the lack of drivers on a particular computer. But, when problems are noted on each device, most likely the problem is in the drive.
Utilities for flash drives
You can try to restore the USB storage device to work using the system utilities.
But, when the problem is serious, the best option is to restore through a program specifically designed for repair.
Some manufacturers make their own apps that do the best job of repairing these particular brands.
Although, with their help, you can recover any brand of USB drive.
Advice: Special programs are designed for refurbishment, not refurbishment. It is not recommended to extract information with their help.
JetFlash Online Recovery
To restore non-working Transcend drives, the manufacturing company has created a special utility that can be found and downloaded for free on its official website.
Adata
The manufacturer Adata also has a freely available program for recovering a USB drive on the official website.
In some cases, the application manages to save part of the data, even if the USB drive has been formatted.
Recovery, unlike most of such programs, can be used not only for video, audio and photo files, but also Word documents, e-books and spreadsheets.
Universal programs
In addition to specialized software that repairs mainly drives of its own brand, there are several applications that can restore the operating state of most devices.
One of them is D-Soft Flash Doctor, which provides the following benefits:
- Menu and documentation in Russian;
- Lack of localization for individual brands;
- Creating a flash disk image for further work not on the drive, but on its virtual copy.
The following programs, not so well-known, but also free and quite effective, are:
- ChipEasy, which is able not only to easily restore a USB flash drive, but also to recognize the manufacturer if its name is not written on the case or has been erased over time;
- Flash Drive Information Extractor - a utility capable of providing the maximum amount of data about a USB flash drive along with its recovery;
- CheckUDisk is a very fast and detailed application for all its ease of use.
Flash drives and various SD cards are still a very common storage medium. Although we strive to move everything to the clouds, the availability of the Internet, its speed, privacy and other factors still slow down the process. Usually, this is such a common experience of communicating with flash drives, she "died". It can happen at any moment, usually it is unexpected and painful. And recovery from solid state drives is more difficult and less effective.
So how do you check your USB stick?
There is an amazing tiny utility Chek Flash to have which at hand does not hurt at all. What can the program do?
- Functional check
- Measures read and write speed
- Edit section information
- Back up and restore full images of partitions and the entire disk
- Wipe content completely (be careful!)
Features of working with the program
If there are some signs that something is wrong with the media: errors, formatting suggestions, speed of work, etc. Choose to check a flash drive with an access type - use a temporary dump, often this test is enough.
In all other cases, copy the content using disk imaging as shown in gif, or in a way convenient for you.
More complex reading and writing tests are best done on an empty flash drive or memory card, so as not to lose information. But the picture of these tests is more accurate and detailed.
The entire set of procedures is available in one window, actions and parameters are divided into blocks, everything is clear and understandable. The utility does not require installation, unpack and run ChkFlsh.exe be attentive and patient. Some tests are quite lengthy, it all depends on the carrier, its speed and condition.
I recorded a short video that shows the capabilities of the program and where the various items are.
Conclusion
How can you take advantage of the verification results? Everything is simple, in the section Information there is a field with the number of errors, and in the block on the right you can understand in which block it happened. Decoding the colors in the tab Legend. In terms of read and write speed, everything is obvious, the larger the numbers, the better! This utility is still a great option for checking Chinese noname, as well as other manufacturers, which are not always true.
How to check a Chinese flash drive for authenticity? How to check if a memory card is fake or not?
Very often I had to deal with flash drives and memory cards with a fake size. Very often, Chinese website sellers sell fake flash drives and memory cards. The product description says 16 GB, 32 GB or more, and when you try to write to a USB flash drive files are often inaccessible.
I personally got such a flash drive in a DVR. After recording 40 minutes of the trip, the DVR started recording video for 3 seconds and then tried to record it again. It's all about the memory card.
And our Chinese friends do it very simply. The file table is written to a memory card or USB flash drive in a "circle". Because of this, the computer displays the size of the flash drive, for example, 32 GB, and the real volume is only 4 GB.
Therefore, do not rush to confirm your order on aliexpress.com or other sites. First check the flash drive with the h2testw utility.
The same is true for the read and write speed. Very often sellers deliberately overstate the class of the memory card.
How to test a USB flash drive or memory card with the h2testw.
Myself The flash memory testing process can be divided into 2 stages:
1.
Filling the entire free space of the tested disk with information (files - the size and number of files is chosen by the H2testw program itself depending on the free space of the tested disk), while the actual write speed is measured.
2.
Reading the recorded information from the tested disk, while measuring the actual reading speed, and the reliability of the information, i.e. check with the information that was previously offered for the record.
This test allows you to determine:
Real speed of reading / writing information of the tested flash memory.
-True volume of the checked information carrier.
Choosing a language "English"
Button "Select target" select the desired drive.
Selecting an item "All available space"(testing all available memory)
And press the button "Write + Verify" and wait for the end of the process.
Attention: The read / write speed in the test will be real only if you use a high-speed USB port and test the memory card without an adapter. If an adapter is needed, it is best to use a quality card reader.
As you can see from the screenshot, the drive was tested successfully.
But there is another option:
The media is likely to be defective.
1.8 GByte OK (3954734 sectors)
5.8 GByte DATA LOST (12240850 sectors)
Details: 2.9 GByte overwritten (6240208 sectors)
0 KByte slightly changed (2.8 GByte corrupted (6000642 sectors)
8 KByte aliased memory (16 sectors)
First error at offset: 0? 0000000000003830
Expected: 0? 358d089906064530
Found: 0? 158d089906064530
H2testw version 1.3
Writing speed: 1.58 MByte / s
Reading speed: 5.56 MByte / s
H2testw v1.4
And in this case, the memory was tested, with the declared volume of 8GB, but only 2 GB (1.8 GByte OK) is available for normal use, the rest 6GB (5.8 GByte DATA LOST) use is not possible. Average speed for a given storage medium = 1.58 MByte / s, average read speed = 5.56 MByte / s
This is how you can test a USB flash drive or memory card
There are flash drives that work in any conditions, in any way with them.
And there are those that you throw off the document you need, and he simply does not want to be copied to this USB flash drive.
Or maybe you threw everything that you need on it, and then you try to open, view the document, but it does not open and is not transferred to the computer. In all this, the saddest thing is that this can happen with any file on your flash drive, be it music, picture or video, nothing can resist the incomprehensible creatures that have settled on your flash drive.
I think you guessed that we are talking about ordinary file system errors.
The question immediately arises, what to do, how to cope with this ailment?
What is the chkdsk application used for?
Let's talk about a certain Check Disk application, or as it is customary to call it chkdsk for short.
Check Disk does its job - it scans the space of the flash drive, sees and finds damaged clusters, calculates all errors, and the main thing is fixing them.
Command: CHKDSK [volume: [[path] filename]]]
checks the specified disk using the Check Disk program; when called without arguments, the current disk is checked. Drive into the console without brackets. Example: C: / F / R
volume - defines the volume label of the checked disk, mount point or disk name with a colon (for example, C :);
path, file name - the name of a file or a group of files to check for fragmentation. Used only in the FAT / FAT32 file system;
/ F - check for errors and fix them automatically;
/ R - search for bad sectors and restore their contents. Requires the mandatory use of the / F key;
Information from Wikipedia - http://en.wikipedia.org/wiki/CHKDSK
How to check a USB flash drive step by step
First, open "My Computer" and find which volume label was assigned to the flash drive.
There is no need to look for the Check Disk program, they took care of you in advance and built everything into your computer.
1. We go to "Start" and type cmd in the search - this step is optional, but I usually do this to see the result of the application.
2. Launching the cmd application, type the line chkdsk g: / f / r by changing the label of the volume g: in it to the label assigned to your flash drive.
3. We see the progress and result of the check.
chkdsk - check result
If the flash drive is not cured, then what to do
Alas, no matter how good CHKDSK would be, it is not omnipotent either. It happens that even after checking it, the flash drive remains with errors. And in this case, everything is not as happy as it seemed before. You can, of course, try to find some program for treating errors on a USB flash drive, but most of the existing programs work on the basis of CHKDSK.
And in the end, there remains the low-level formatting of the flash drive and.
If the information is very important, then you can try at home.
Are there any additions?
