我隻USB係咪壞左?

Seems some error on your USB Stick try to copy out all existing file from your USB stick to local hardisk.

Reformat the USB Stick and see the problem able to resolve or not otherwise take to the supplier there to let them fix it.

Hope the information help!

Cheers!

如果有個指令彈出,我認為係你隻手指有毒所致
試下用一部無毒電腦掃下佢

　　試一試 Format或格式化有關的 USB 手指，因為中病、FAT32 損壞都會這樣的。
