Erasing a Read/Write (RW) Disc

If you have a read/write disc (such as a CD-RW or DVD-RW disc) that already contains files, you can erase those files by erasing the entire disc. Here’s how to erase a rewritable (RW) disc that already has data stored on it:

2. Start the Disk Utility, located in the Utilities folder. The Disk Utility window opens, as shown in Figure 13-1.
