In the previous article, Mytour provided readers with the best USB data recovery software to retrieve data in case of accidental deletion or other factors.
However, prevention is better than cure. Instead of waiting until data loss occurs to worry about data recovery, you can set up to protect your USB device and prevent data loss. Refer to the following article by Mytour for implementation methods.
5 Effective Ways to Secure Your USB Device and Prevent Data Loss
5 Effective Ways to Secure Your USB Device and Prevent Data Loss
Below, Mytour will introduce and guide you through 5 methods to secure your USB device and prevent data loss:
Method 1: Set Write Permissions
To prevent other users from modifying files and important data on the USB device, you can manipulate and modify values in the Registry. By doing this, other users are only allowed to access data on the USB and do not have permission to change or modify this data.
Method 2: Control USB Attack Viruses
Sometimes your computer may be infected with viruses or malware, Trojan attacks that you may not be aware of. In general, when connecting a USB device to a computer, viruses can attack your USB and destroy your valuable data. To control USB attack viruses, the best way is to set up access denial for all accounts on the USB device.
Method 3: Hide USB Drive on Computer
When a USB device is connected to a local computer, Windows will automatically open windows for the corresponding devices, allowing users to quickly access their files and data. Network viruses may exploit this process to corrupt data.
Method 5: Setting up USB password
If you find it inconvenient to have to manipulate to display the device every time you connect and use USB, you can set a strong, hard-to-guess password for USB usage. You can refer to the guide Setting up USB password, create a Password to protect USB with USB Security to do this.
Additional information about USB and USB devices
USB was first introduced in late 1994, specifically on November 11, 2014, and was proposed by Intel, Compaq, IBM, Microsoft, and several other companies. The USB 3.1 version is the latest device version today.
The outstanding features and advantages of USB are fast transmission speed, convenience, flexible connectivity, independent power source, etc. The device plays an important role in connecting computers to most external devices, such as mice, keyboards, printers, scanners, cameras, chargers, USB, MP3 music players, mobile phones, digital cameras, portable hard drives, USB sticks, ADSL modems, and cable modems.
Structure of USB
The structure of a USB drive is divided into two parts: software structure and hardware structure. Specifically:
1. Software Structure: Each USB has only one host and the host software is designed based on modules and object orientation. USB software typically consists of 3 main modules: Universal Host Controller Driver (UHCD), USB Driver (USBD), and USB Client Software.
2. Hardware Structure: USB uses a 4-wire cable. Two of them are channels used for data transmission, and the remaining 2 wires are used to supply power to downstream devices.
For high-speed peripheral devices requiring high bandwidth, USB data transfer speed can reach 12Mbps. However, for low-speed peripheral devices, USB will only transmit data at 1.5Mbps. In other words, the USB bus will automatically switch between these two modes depending on the peripheral device.
Applications of USB in daily life
1. USB data storage devices: including external USB hard drives, USB Flash Drives, SD cards on mobile devices, TF cards, USB memory cards, ... .
2. USB ports on computers: both the front and back of the computer case have USB ports for connecting peripheral devices, such as portable hard drives, USB Flash Drives, ... . By connecting peripheral devices to the computer, users can easily manage data.
3. Wireless USB technology: Wireless USB technology allows users to connect peripheral devices to computers without using complex wired connections.
The standard data transmission speed on wireless USB devices is similar to wired USB 2.0 standard (480M/s), except that wireless USB requires a wireless transmitter and receiver to be equipped on the computer and peripheral device.
4. Here are some specific applications of USB devices:
- USB Modems.
- USB Speakers.
- USB Hubs.
- USB Sound Cards.
- USB Cameras.
Here, Mytour introduces you to 5 ways to protect your USB devices safely, avoiding data loss. Prevention is better than cure, so ensure data security beforehand. In case of data loss, traditional recovery methods might prove costly, requiring expert intervention or specialized data recovery services.
