I don't know how or when this happened, but my MacBook(White 2Ghz) won't mount the volume of anything USB unless it's connected at startup. So if i wanna sync my iPod Shuffle or copy off an HD i have to connect the device and then reboot. I've tried this with the forementioned Shuffle, iPod touch(running the 3.0software) various USB flashdrives, a FAT32 USB 2.5in 320GB drive, an NTFS 250GB Drive(using Paragon's NTFS7.0.1) and a USB DVD-RW drive...
