USB devices must be ejected prior to removing them from a computer or shutting down. The device is ejected to avoid disrupting data being written. If you detach the device without properly ejecting it, the data encoding process falls prey to corruption.

In this post, we’ll explore how to eject USB from Mac safely, why it’s important to exercise care and we’ll talk about various ways to achieve it.

Part 1. Is It Safe to Remove USB without Ejecting Mac?
Do You Really Need to Safely Remove USB?
Why is it important for you to know how to eject USB from Mac safely? There are some disadvantages if you don’t remove your USB safely below:
1. Abrupt Detachment of USB May Corrupt Data
The Operating System employs write caching making it important to abide by the appropriate ejection process. With the file at the ready in the execution state, the OS delays the encoding process and caches the data until other operations finish. If you detach the USB with a cache underway, your data may get corrupted.
Safely removing the external device consummates the cache or the remaining data and screeches any ongoing processes in the background to a halt.
2. Impairs the Logical File System
Another detriment of unsafe ejection of USB is the impairment of the logical file system. Unsafe ejection destroys cells. These cells store internal drive data and any damage could render the existent information inaccessible.
3. Data Loss
Removing a drive prematurely while it’s still in use opens a new can of worms. It triggers corruptions that essentially compel you to reformat the drive completely. Without backup, you could be caught napping. This is why your Mac displays a message to remind you to eject drives safely.
Below are examples of circumstances where removing a drive prematurely can damage the USB:
- Running installation for files via the USB
- Copying files from or to the flash drive
- When an open process is using contents from the drive
- When the USB is in the process of being wiped out or formatted
