Disassembly of Simple Drive Deluxe

If two screws loosened but the other two won't catch, double check that they're actually Phillips screws and not Torx or a security variant, as older external drives sometimes use different screw types in the same enclosure. Try applying firm downward pressure with the correct sized bit and inspect the screw heads with a flashlight. If the drive itself is still healthy, removing it from the enclosure and connecting it through a compatible adapter is often the easiest way to recover the data.
