2. What is the technical reason why you must properly eject media?

File I/O is buffered. If you remove the media before the buffer is cleared, files remain open and potentially corrupt.

The Storage Inventory Manager (SIM) can lose its drive references, which may corrupt other storage in the system.

The drive must receive the eject signal and turn itself off, dropping the DTR signal and indicating the media is safe to remove.

The computer must stop the 5-volt signal to media, otherwise the drive may short.

Answer

Correct Answer: File I/O is buffered. If you remove the media before the buffer is cleared, files remain open and potentially corrupt.
