USB Drives not being found


I have just recently installed ATV Flash and can’t get it to recognize my external hard drive. I did a complete system reboot–took it back to factory settings, updated the Apple software, installed ATV Flash, ran smart installer. The drive in question is a 250 GB Seagate drive that I made sure to format in FAT32. When I go to switch from internal to external iTunes, it doesn’t find the drive. I tried different HD’s, flash memory sticks–nothing I put in the USB is recognized. I have re-run smart installer. I have tried plugging in the drive before start up, after start up–everything. Any help?

I have the same problem!
