Eject may refer to any of the following:

CD-ROM eject button

1. With removable disk drives, eject means to disengage the medium (removable disk) so it may be removed. For instance, with a CD-ROM drive, ejecting the disk opens the tray. Or, if the CD-ROM drive uses slot insertion, ejecting will mechanically reposition the CD so it sticks out of the slot.

The picture is a close-up example of what the eject button looks like on the front of a CD-ROM drive. It's usually represented by a small triangle with a line under it and found on the right side of the drive.


Many software programs allow users to eject a CD without having to push the eject button.

Eject USB thumb drive in Windows

2. With USB drives, eject is an operating system feature that lets the operating system known the drive is about to be disconnected. The operating system completes any read or write operations on the drive, and unmounts it from the computer.

If you do not eject a USB drive before it's disconnected, there's a chance that data on the drive will be corrupted. For this reason, it's best to always eject your USB drive before physically disconnecting it from your USB port.

Floppy disk drive eject button

3. With floppy disk drives, eject is the action of disengaging and removing a floppy diskette from the drive. To eject a floppy diskette from a floppy disk drive, press the eject button on the front of the drive. The diskette is ejected part way, allowing you to grab it and carefully pull it out the rest of the way.

The picture is an example of the eject button on a 3 1/2" floppy disk drive.

4. With Linux and Unix, eject is a command to eject removable media using the command line. See our eject command page for further information about this command.
