💾 External hard drive

External hard drives and SSDs sometimes look dense and cluttered on the X-ray, which can cause a screener to request a bag check. They'll simply swab it or take a closer look — there are no content restrictions on the drive itself. Keeping it in an easily accessible pouch or removing it from your bag proactively can speed things up.

External hard drives are permitted as carry-on items in all major aviation systems with no quantity or size restrictions. There are no regions where they are specifically restricted or require special declaration for the drive hardware itself, though customs officials at your destination may ask about them separately from airline security.

Most airports only require laptops to be removed from bags at the checkpoint — external hard drives can generally stay inside. That said, if your bag is flagged for a secondary scan, having your drive in an easy-to-reach spot will make the inspection faster. At stricter checkpoints or during busy periods, removing it proactively can save time.

Carry-on is strongly recommended for external hard drives, especially spinning-disk HDDs that can be damaged by rough baggage handling or the vibration and pressure changes in the cargo hold. SSDs are more durable but carry-on is still preferable to keep your data under your control and avoid potential damage.
