HELP ME!!! I have installed an xServe into a school and our purchasing people stupidly forgot to specify the additional 1Tb Hard Drive... Consequently we have 700 users using the 160Gb Hard drive - needless to say, it is now full (2 months later!) In putting in a new drive, do I need to buy the apple specific drive? Does the xServe that I have installed (the latest generation) already have the drive bays so that I can install a third party drive or is this another way that Apple will screw me for every penny I have?! Thank you all in advance - this is urgent!
