Hey guys i got a problem!

I formatted one of my maxtor external hard drives and installed snow leopard and all the updates and all my software on it using my Macbook Pro. Now when I boot and hold down the option key nothing happens!

The only way I can boot from this disk is by going to startup disc and selecting it and setting it as the default start-up disk.

NOW, the real problem is trying to boot my Mac Pro from the disk! When I turn on the Mac Pro and hold down option the menu comes up, but I dont see the external drive, and if i boot using the regular HD and set it as the default nothing happens.

Theres the formatting for the drive if that has anything to do with it!

Thanks for the help!
QUOTE Thanks
