詳細錯誤： "The installer encountered an error copying files to the hard disk: [Errno 5] Input/output error This is often due to a faulty CD/DVD disk or drive, or a faulty hard disk. It may help to clean the CD/DVD, to burn the CD/DVD at a lower speed, to clean the CD/DVD drive lens (cleaning kits are often available from electronics suppliers), to check whether the hard disk is old and in need of replacement, or to move the system to a cooler environment."
環境：U盤裝ubuntu，版本：ubuntu-10.04-desktop-i386.iso，製作工具：Universal-USB-Installer-1.9.5.2.exe。
用ubuntu-12.04-desktop-i386.iso裝時都沒出現這個錯誤，難道是ISO有問題？
