![]() Unplugging a USB drive, especially when it’s still communicating with the operating system, can lead to data corruption. If, however, you choose to skip this step, i.e., not click on “safely remove hardware” – especially when data is being written on it – then it might potentially lead to data corruption and data loss on the external drive. When you click on the “safely remove hardware” option, you basically instruct the operating system to wait for all processes accessing a file system to finish, and then dismount the file system, which prevents any more read/write operations for the external drive. Data corruption simply means that the data you copied to the USB drive could not be properly written, and could therefore potentially be unreadable when accessed later. This might lead to a ‘corruption’ of the data on the USB drive. ![]() Suppose you start copying a few large video files to your USB drive, but before they are completely written (i.e., the progress bar has reached 100%) on the latter, you suddenly eject the USB drive from its slot. When you move data from one drive to another (e.g., a USB flash drive to an external hard drive), it takes some time, depending on how much data you are moving and how fast your computer is. What happens when you select the “safely remove hardware” option? So, what is actually happening when you instruct your Windows computer to safely remove hardware? And why is it considered “better” for your computer? More importantly, is it necessary to follow this practice? Then I observed a couple of my friends who always followed this so-called healthy practice. When I first started using USB flash drives to transfer and store data, I wasn’t very careful about using the “safe to remove hardware” option (in Windows computers) before removing the drives from the CPU cabinet/tower. ![]() The process essentially tells the computer to wait for all processes accessing a file system to finish before dismounting the file system, which prevents any more read/write operations from occurring. Safely remove hardware is a process in Windows computers that helps to prevent data corruption when external drives are removed.
