Transfer of Library to a back-up External HD


My iTunes library (about 500 gigs) is loaded on a Raid-1 Cavalry external HD. In an attempt to get additional back-up I purchased a new FreeAgent Desk 1 TB external HD. The Mac recognizes both HDs, however when I attempt to click and drag from the Cavalry to the FreeAgent the response on the monitor is, in so many words, the transfer can not be completed because the FreeAgent cannot be modified. This was supposed to be super simple according to the Geek at Best Buy. Am I doing something wrong here? The Cavalry is connected to the Mac via Firewire, the FreeAgent is connected via USB.

My guess would be that the FreeAgent HD is preformatted to Windows-compatible. With my MacBook, I have a Windows partition that doesn't allow me to copy files directly between the Mac and Windows partitions.

Like the previous posters, use Disk Utility to reformat to Mac-compatible and the disk permission issue should be fixed.
