Hello there, thanks for the reply. Before writing it down to forum, I’ve also wrote it to support. And I’ve got the following answer which satisfies me;
"I understand that your new SSD is working just fine in your system.
Regarding the HDD, whenever you turn off the computer inside the OS(no hard reset/ shut down), all the drives connected to it always to stop working safely. There is no danger for the HDD, if you shut down the system according to the operating system instructions.
What O/S are you using exactly?
"
For your suggestion I can tell, I was using the same hdd in the SATA3 port which I use for SSD now. So both the Sata3 port and the hdd works fine. There is no defect. I still can use the hdd in the cd rom drive. I guess it is about the cd rom drive. As you said it does not need to shut done safely since there is usually no cd inserted to safely remove. Is there any way to turn it off safely while laptop is turning off?
