Hi all, I have nearly filled by internal hard drive on my iMac (500GB). The bulk of the files are itunes (approx 350gb and growing all the time). Issue 1 - iTunes Library I plan to move my iTunes media (though not the library files because I understand I may experience speed issues) to an external hard drive. I have researched it and I think I am going to go with a 2TB WD Studio. I will connect this to the Mac via Firewire 800. This HD will be connected permanently and will effectively be an extension of my iMac. I think I am comfortable with that solution - though I would appreciate anyone's comments if they think my plan if flawed. It is my second issue that is causing me a headache... Time Machine. Issue 2 - Time Machine I currently use time machine with an old Toshiba HD connected over usb. This drive is not connected permanently (I am paranoid and like to keep the drive away from the computer when I am out of the house). With my new HD attached (let's call this the "iTunes HD") my Toshiba drive will clearly not be sufficient to continue as my TM drive. I fear this may mean I actually have to buy TWO WD Studios (not an appealing prospect for obvious reasons). My question: I am not familiar with Firewire but I understand I can daisy chain devices. On that basis, would it be possible to connect my TM hard drive to the iTunes HD and initiate a TM backup of the iMac AND the iTunes HD (as one) or will I have to connect the TM drive direct to the iMac and perform a back-up of both that way? The iMac has only one Firewire port you see and I don't partcularly want to perform Time Machine back ups over USB if I can help it (I know I do that now but it is a pain and I need my usb ports). I am sorry for rambling. It is all a bit of a nightmare. I am not exactly flush with cash but I need a good solution. I am also very disappointed that I can't utilise (meaningfully anyway) a perfectly good 500GB Toshiba drive! Thanks in advance for your help.
