People said that harddisk need to be refreshed to prevent bit rot by format the drive, then recopy the files back.
I have external hard disk, and use it as backup purpose once in two weeks. Am I need to "refresh" it just like people said?
How about usb thumb drive? Need refresh too? What I know is we need to plug in flash drive periodically to prevent data lost. But I dont know if we need to format and recopy data (refresh) or not.
