Another way to test this is to try copying the entire contents of the installation CDs to your hard drive:
1. First, make a new folder on your desktop and name it something like “WoW Installer.”
2. Open up the disk itself:
- Windows users should go into My Computer, right-click the CD, and choose “Open.”
- Mac users can simply double-click the CD on their desktop.
3. Go to the Edit menu and choose “Select all”, so all the files are highlighted.
4. Go to the Edit menu and choose “Copy.”
5. Open the new folder you created on your desktop
6. Go to the Edit menu and choose “Paste.”
7. The files should copy from the CD to that folder.
8. Once this is complete, please put in the next install disk.
9. Open up the disk (using the process in step 2 above).
10. Select the file called “Installer Tome” with the number at the end.
11. Go to the Edit menu and choose “Copy.”
12. Open the new folder you created on your desktop
13. Go to the Edit menu and choose “Paste.”
14. The “Tome” file will copy over.

Repeat steps 8-14 to get the “Installer Tome” files off the third and fourth install disks. If you receive any error while copying any of these files, that typically indicates damage to the disk.
