Back in Europe, I was using a PC to digitalize my whole CD library and saved everything on my external harddisk drive. When I came to the US, I bought myself a Macbook. The problem is that using iTunes, I can read and play all mp3s really good, but when I change f.e. the name of one of the files, it is much slower than it was comparing my crappy PC. I was wondering if there might be something special with these files since I was switching from PC to Mac, and I would be able to do something against this, f.e. defragmentation? The harddrive is connected via USB to my SR Macbook, and it is formatted with FAT. I would be really glad about some help!
