I'm a proud owner of an iMac, the problem is, even after I updated to iTunes 7.7, my itunes is running slow. Now, I have the new 2.8Ghz 24" iMac. I'm thinking that the problem could be of either: 1) Using my "MyBook World Edition(1Tb)" via Ethernet as a direct HDD as I do not want to clog up my iMac HDD, I'm storing other media files on there too. 2) Files are recording in the format of .AIFF. Now I'm 99.9999999999% sure that it is not the second & more the 1st. I'm about to test my theory as Im copying all my audio files over to my Mac HDD & restarting without the MyBook attached to the machine. Can anyone suggest anything else. Was thinking of hacking the MyBook & formatting it to the Extended format but reading into it more, apparently I would have been better off buying a FireWire drive. My only bug bearer is my Dad has a 500Gb Ext HDD via FireWire but it really slows the iMac boot time down by quiet a bit... Some one please help, I brought an iMac as they are smooth & do not hang like a Windows machine? The Only other option was to use my old PC as NAS using FreeNAS? Anyone?
