Wait about 20 seconds, then spin down the motor:
=>我的情況是沒辦法等20秒再輸入Z ,要馬上輸入Z否則會持續出現錯誤訊息LED: 000000CC ,一定有必要等待20秒嗎??

F3 2>Z (enter)

Spin Down Complete

=>我的情況是沒出現Spin Down Complete訊息 ,而是LED:000000CE FAddr:0025CBC3 ,而馬達確實停止了!

If you instead see a message similar to this:

LED: 000000CE FAddr: 00280D4D

Then you entered the commands too quickly after supplying power to the drive. Cycle power, wait 20 seconds, then begin again.
=>我的情況的確是出現錯誤訊息LED: 000000CE ,所以這段話的意思是否是表達要在pc開機的狀態下熱插拔問題硬碟的電源呢??硬碟可以這樣熱插拔電源嗎??會不會燒壞??

謝謝!!
