EXPLAINED… Inside an external drive
Seagate’s drive circuitry is found in this plug-in attachment; other drives integrate it into the chassis.
Screws are rarely used with external hard drives. Instead, they use a series of tabs you need to prise open.
The internal disk is like any other, but you’ll need to remove any attached extras.
Thankfully, installing or removing a disk from replacement drive enclosures is a much simpler process.
