Fresh Arch Linux install, working USB thumb drive (Windows, previous Arch Linux setups, etc.), formatted FAT32.
Seems to randomly reset, eject, and auto-re-mount during extensive file operations (i.e. copying 4gb worth of 800 files from the USB thumb drive to disk).
I've tried various USB ports to no avail; no external hub being used.
Thoughts? Not sure where to begin diagnosing:
