Do you really need to “safely” eject a USB drive?
Knowing how and when to eject a USB drive isn't complicated.

For years, the rule has always been to eject your USB drive before removing it from your computer. Of course, a lot of people ignore this outright and just yank the drive, and for the most part, their data is fine. So, is it safe to pull a drive without first properly ejecting it? Almost always yes, but sometimes — rarely — no.
