The previous article – “What Will Happen if USB Flash Drive Is NOT Removed Safely?” has exposed the terrible consequences of unplugging external drive from PC abruptly without safely removing it.

Yet, to be honest, you should never unplug the external drive abruptly in the following 4 situations. Otherwise, the drive may be damaged and drive data may be corrupt or lost forever.
1. When Copying/Moving Files from/to the Drive
File copy or move is a frequent operation for al computer users. For instance, so as to access some important and frequently-used files more easily, you can copy or move the files from your computer to a portable USB flash drive. Then, you’ll plug the USB drive into the PC and copy files to it. In this process, especially if you use “cut + paste” to move files, you should ensure the drive connected all the time. Or else, the files in copy can be lost.
2. When Data on the Drive Are Read/Written
To read or write the files on an external drive, you have to connect it to computer. For example, you need to re-edit an existing Word document stored in the drive. Thus, you connect the drive to computer and then open the document by the MS Word application on PC. In this course, you have to keep the drive connected. If it is removed suddenly, not only will the changes on the document not be saved, but also it can be corrupted directly, like corrupt PST file.
3. When the Drive Is Reformatted

Or if you would like to change the drive format, such as from FAT32 to NTFS, you need to reformat the drive. During reformatting, you have to keep cautious and never disconnect the drive. Otherwise, drive reformatting will fail and the drive can be inaccessible thoroughly.

For example, you can run CHKDSK to repair errors and antivirus software to remove potential viruses on external drive. Yet, in this process, you shouldn’t unplug this drive abruptly, which can damage the drive further.
