Today, perhaps USB Flash Disk is the most popular data traveler. It had long replaced floppy disk as rewritable recording medium, today almost no PC have floppy drive. This USB Flash Disk has more advantages than floppy disk. It has larger capacity (there are up to 4 Giga Bytes, and increasing) and more resistant to damage because of its solid state. We also can use it to install operating system such as Windows XP, Windows 7, and even Linux to PCs and laptops.

It is recommended when we unplug Flash Disk from USB slot, click first Safely Remove Hardware. This is to make sure that there are not processes of writing, reading, or erasing files to Flash Disk. If these activities is interrupted by unplugging Flash Disk, there is a possibility of damage. In my experience, most damages occurred from failure to complete these process. Note that Safely Remove Hardware can not be executed when the process of writing, reading, or erasing files to Flash Disk still running. The hint that process still in run is indicated by blinking LED of Flash Disk. So don’t ever try to remove USB Flash Disk when the LED is still blinking. We can remove it directly anytime if we are sure that there are not any processes of writing, reading, or erasing files, but consider the risk.

Generally, USB Flash Disk will defect across time. Slowing process of writing, reading, or erasing files is the most visible indication. Please remind that its function is as data traveler, to transfer data. It is not recommended to keep data in data traveler in long time.
