I have a M9 which is an external hard drive i have used it as a
Mac time machine backup drive b4 but now i want to use it for my pc
so i reformatted the hdd using mac's disc utility and when i plug
in the drive to my pc it plays the sound when you insert a
hdd/thumbdrive in but when i go to My Computer the drive isnt
listed however, i can read the drive using my macbook
Format using ur pc...not ur Mac.
