Step 4: The flash drive will be erased during installation. Be sure to backup any files on the drive you wish to keep!

Question if I select the /dev/disk2 FLASH DRIVE and it stats "WARNING: The disk will be erased!!!

what exactly is getting erased? Just don't want to do something dumb.

 

Thanks in advance

The aTV Flash (for silver AppleTV) will erase the flash drive before installing the aTV Flash software onto it. The flash drive installation process is not required for the black AppleTV.

Are you using a silver or black AppleTV (your comment was posted in the black section).
