Re: I/O Device Error when copying from External Drive
Is the front panel USB a standalone device that fits into a 3.5" bay? If that's the case, the speed might be restricted by the USB 1.1 standard, or it's possibly faulty.
I'd also check the BIOS and make sure all USB settings are set to "High Speed"/USB 2.0 and not "Full Speed"/USB 1.1.
One last thing to check is where the front panel USB is plugged in. It's possible the header you have it plugged into on the board is having problems. Just try another header.
If it's the type of front panel USB that is esentially an extension cable/hub that literally runs a USB cable through the machine, out the back, and gets plugged into a rear panel USB port, I'd advise getting a new one.
