Your machine gets so cross with you when you don’t safely remove a USB or hard drive, but is it really necessary?
The reasoning behind it
In general, the answer is yes, but why?
Most Windows and Apple operating systems perform write caching. What this means is that your machine, in simple terms, waits to perform certain actions and then performs all these actions at once. If you don’t let the machine know that you are about to eject a disk it won’t perform all these pending actions and the data could become corrupt.
Regardless of write caching, if the drive is in use you should always safely eject disk to prevent data corruption.
Tip: Most USBs and hard drives have a little light which will be an indication of whether it is in use.
