Live USB Inaccessible After Reboot

I'm trying to run Fedora off a USB drive. It's booting OK, and persistence is working perfectly. I'm facing a problem now where whenever the system is rebooted, BIOS can't see the USB drive until I physically disconnect and reconnect it.

At first I thought it was a hardware/firmware issue but it works fine in Ubuntu, so I guess Fedora is 'ejecting' the drive in a shutdown script or something.

  • The USB drive was built in Windows 7 using live-usb with Fedora-16-x86_64-Live-Desktop.iso and 4GB persistence
  • It's an 8GB Corsair Flash Voyager USB 3.0
  • Motherboard is an ASRock Z68M-ITX/HT
  • Issue occurs regardless of whether the drive is booted via USB or UEFI

I've only been able to find one reference to similar issue on the net, but there was no workaround, so any assistance would be much appreciated.

Fedora will unmount the device at poweroff, but that shouldn't cause the BIOS to not detect it. Something else is at play here.
