Hello everyone. I have Lion OS X and I just purchased a 32GB HP flash drive. I reformatted it, and I can get it to read in any other Mac or PC but my own. I reset the PRAM, SMC, and started a new account, and it still didn't work. It shows up in the system profiler, and the only way I finally got it to mount, after a long time, was by using the USB profiler. I even booted my computer from an external HD with my school's Lion image, and it showed up immediately. What could be causing these problems?
