As the tittle says I need a internal TB hdd since the screenshot it is visible that it is going bad anytime soon.
Now the problem is that this is going to be installed on my about 7 years old pc which is used for the purpose of only downloading. So the basic problem is that I have no Idea that what motherboard it has since it was a manufacturer made PC not assembled.
Now how do I know what motherboard is it I need input on this matter.
Thanks in advance
