I'm wondering will traditional hard drives (non-SSD) stop working after idle without power for a long period of time. My friend discussed this issue with me and his 1TB hard drives failed when he try to get the data after idle without power for almost 2 years. I've many hard drives for data storage but they will not be connected except to get the data from the drives, they will store in a dry and cool place in their original packages. Is the issue which my friend told me is true? Thank you very much!
