Hi, i'm not new here... But i forgot my old account's name. Whatever... I Fix windows computers. So I use an 8gb thumb drive with an iso restored onto it. (the way you do it with with Disk Utility). It has fixes to some basic windows problems. Here is the problem: it got kinda messed up, and when I hook it up to my Mac to swap the images that are on it and stuff, Finder freezes up and wont relaunch untill i pull the thumb drive out. Then my computer yells at me. I just want to give it a clean formatting to work like a regular thumb drive again, (not a boot disk) but when i get as far as erasing it in Disk Utility, a message comes up saying "Error, Failed to unmount" or something very similar. How can i just... format it to be a regular thumb drive again? I dont need any data from it. I have 10.4.11 if that helps at all. THANK YOU SO MUCH!
