Hey Mac Rumours forum members, I'm new here, and I'm very new to the Mac world. I just bought my new iMac 24" 2.93Ghz 4Gbs Ram computer last weekend. I have a western digital mybook 500 Gb external hard drive in which I used to store my music and my photos on to. Well its in NTFS format, so I copied everything on to my iMac hard drive. So I was thinking of copying back on to my western digital mybook hard drive. So I have to change the hard drive format which is NTFS. Could I do it through iDisk Utility, and how can I do that ? And which format do you suggest ? Does Mac read FAT32 ? Coz I was thinking of having it in a storage format that it would be readable for Windows & Mac. I also need another suggestion, regarding storing my music & photos. Should I have it on the external hard drive, so I leave my iMac free? Then link iTunes to my external hard drive. And could I change my iPhoto to link to my external hard drive ? My iMac hard drive by the way is 640 Gbs. So what do you all suggest people for me to do. I really wish advice before I settle down with all my files in place in my iMac. Thanks to anyone that helps me out !
