This instructable is for the safe disassembly of Seagate 3.5-inch Pushbutton Backup External Hard Drives as seen here: http://www.seagate.com/www/en-us/products/external/pushbutton_backup/
First of all, why would anyone want to take this thing apart? I personally love the design. It looks great, it's quiet, reliable, stackable, and portable. Sure, it needs an external power source, and it's becoming a bit large for today's external hard drive standards, but other than that, this thing is pretty well designed, IMO.
But for whatever reason, you want to open the enclosure up. After many exhaustive hours of research, I was surprised to find that there was absolutely no information on the web about taking this thing apart. I had imagined it to be a pretty prolific piece of hardware, but maybe I was wrong. Several people in forums told me it was impossible to take apart without breaking the enclosure, but that is simply not true. In fact, the internal design seems to even facilitate disassembly to a certain degree. Whether this was intended or not, I don't know. In any case, let's get started:
You will need:
Some sort of flat, sturdy tool like a flathead screwdriver
1 Phillips head screwdriver
1 2.4 m/m flathead screw driver OR 1 2.5 m/m Hex screwdriver OR 1 Torx screw bit
1 2.0 m/m flathead screwdriver OR 1 small Torx bit
Obviously, make sure you only work on the hard drive and enclosure while it's unplugged. Also, as is true with all computer electronics, you should try to maintain a non-static environment while working. Use proper safety precaution and go slow. If you get stuck, use the photos as references.
Finally, this WILL void your warranty.
