What screwdriver do I use to disassemble a Seagate Barracuda LP 2TB hard drive?
If you want to have any hope of preserving any data on the drive, then the correct answer is NONE! There are too many particles of dust, dirt, skin cells, and more floating around in the regular air of a private home, business office, hospital, or other facility not classified and certified as a Class 100 clean room. If you open the drive outside of such a facility, then the only way that you will successfully be able to use the drive again is to send it to such a facility for repair and decontamination. Reassembling the drive and putting it back into operation yourself will lead to those unseen particles getting caught between the read/write heads and the data platters, marring the surfaces of said platters and destroying the data.
Now having said this, if the drive is dead and you just wish to take it apart to see what is inside, then you should use a very small Torx bit. Most of the screws tend to be either T-5 or T-8 with T-5 being the smaller of the two. You can pick up these bits at the hardware store.
Why is recommended not to remove the usb device directly?
If the computer is writing to the USB drive at the moment when you disconnect the device, then you could have, for example, a file on the drive with a beginning and no end. Also, if the computer is dependent on things that are stored on the USB drive, then it needs to know before these files disappear. Before you remove a USB drive, the operating system needs to check with all of the running applications to make sure that it is OK. -DJ Craig
