I presently have a Dell Windows XP SP3 machine and I wanted to add an additional HD to this machine, but I don't know how? I'm considering purchasing 1Tb of storage for this HD. On the present HD I have the OS and everything else I'll need. On the second HD, I'd like to store a bunch of files and folders have create three other machines to be able to access them, with some permissions as well. Do I need to do anything to the second HD?
