I just got two 32 gb PNY flash drives and neither of them are being recognized by my Xbox. I have a 2007 Xbox and all of the updates are installed on the Xbox, and I have a 2 gb Sandisk and an 8 gb flash drive (don't know the brand) that are both working fine. I have plugged the new flash drives into both of the USB ports on the front (doesn't fit in the one on the back). I plugged the new flash drives into my computer and made sure they were FAT 32, but they still aren't recognized. I've turned the Xbox on/off, unplugged the power supply, and plugged the flash drives in while it was on, as well as off. Are the flash drives not working because of something with my console, or are PNY flash drives just not compatible?
