So for users' sake, we summarized 4 common problems that may occur during the use of USB data storage devices.After knowing this, you may be able to decrease the possibility of getting stuck in devastating data loss cases.
Unable to Safely Remove a USB Device
Some users may have encountered this situation: when they plan to remove the USB device from computer, they find it can't be safely removed; Windows prompts it fails to stop the device and users are asked to close all possible programs that might be using the device and then try again later. If you insist on ejecting the USB device forcibly, you may finally get a broken flash drive.
At this time, you should resort to following 3 steps to achieve safe removal:
Step 1: please check whether there is any data copying/transfer in progress.
Step 2: you need to confirm no program in Windows is using any files from the USB device to be removed (for instance, a video may be played in a Windows player); if there is, close it.
Step 3: if the USB data storage device still can't be removed after all programs were closed, you'll need to open Task Manager and then close all unnecessary background applications. (If this still couldn't help, you may as well try to close explorer.exe process for the moment)
Please remember, don't try to forcibly remove the USB device from computer in unsafe mode since it is easy to cause serious data loss.

Hide the device drive: if you don't want others to see the data in any USB devices, you may as well try to hide all the drives except for local hard disk drives.

A Comprehensive Understanding of USB & USB Device
At the end of 1994, USB (Universal Serial Bus) was jointly proposed by Intel, Compaq, IBM, Microsoft and other companies. USB version has gone through years of development since its first release – V0.7 was issued in November 11, 1994.USB has the features of fast transmission speed, convenient usage, hot swappable, flexible connection, independent power supply, etc. It plays an important role in connecting computer with almost all external devices, such as mouse, keyboard, printer, scanner, camera, charger, USB Flash Drive, MP3, cell phone, digital camera, mobile hard disk, external optical floppy, USB card, ADSL Modem and Cable Modem.
Structure Parsing of USB
The analysis of USB structure can be divided into mainly two aspects: software structure and hardware structure. Now, we'll talk about them respectively.
- Software structure: each USB only have one host and the host software is designed on the basis of modular and object-oriented method. USB software generally consists of three main modules: Universal Host Controller Driver (UHCD), USB Driver (USBD) and USB Client Software.
- Hardware structure: USB uses four-wire cable. Two of them are the serial channels used to transfer data; the other two are used to provide power for downstream device. For the high-speed peripherals which need high-bandwidth, the USB data transfer rate could reach 12Mbps. Yet for the low-speed peripherals, USB would transfer data only at the speed of 1.5Mbps. In a word, USB bus will switch between those two modes dynamically and automatically according to peripheral.
Applications of USB in Daily Life
USB has been using in all walks of life around the world and USB data storage forms the major part of USB applications. Besides, we'll also introduce some other applications in brief.
1. USB data storage devices: USB external hard drive, USB flash drive, USB mobile phone SD card, TF card, USB memory stick, etc. We bet those USB data storage devices are very familiar to users. Though the capacity of them is often much smaller than that of computer hard disk, they are prevalent throughout the world due to its portability.
2. USB computer case interface: in both the front and back side of computer case, there exist several USB interface to help to connect external device, such as mobile hard drive, flash drive and digital camera, to computer. In this way, data in external device can be managed on computer conveniently.
3. Wireless USB technology: Jeff Ravencraft, chairman of the USB Implementers' Forum and chief technology strategy officer of Intel, said that wireless USB technology is going to help users get rid of complicated cable connections when they need to connect external devices to computer.
The standard data transfer rate of wireless USB devices is the same with that of wired USB 2.0 standard (480M/s) founded in the twenties of the twenty-first century. The difference lies in: wireless USB technology requires a wireless transceiver to be equipped in computer and external device (to replace cable connection).
4. Specific USB applications: following 5 applications of USB may be not unfamiliar to you.
- USB modem;
- USB loudspeaker box;
- USB Hub;
- USB sound card;
- USB computer camera.
However, connecting two computers with the help of USB may be new to lots of users.
Bottom Line
As you can easily find, USB has become one kind of the most important interfaces. With the help of USB, we are able to transfer data among different storage devices easily, without using network. Besides, varieties of USB devices enrich our life and ease our work.Just because USB device is frequently used, problems tend to occur beyond our expectations. But no matter what kind of problem you're meeting, you should rescue data from USB device firstly.
