To remove HDD/SSD, you need to pull disk outwards of connector.

When disconnected, pull up the disk away from bay.

Important! If you wanna place a new disk, make sure it is SLIM format. It is standard for 2,5" SSDs, so nothing to worry about.

2,5" HDDs were made in 2 different thicknesses: standard (9mm) and slim (7mm)

Mine laptop is lacking two rubber bands, that are holding disk. They're not a necessity, cover has some thick rubber on it too, so disk should stay in place.
