Recently my 1TB external hard drive crashed. Luckily no data is there in it. I have couple of other external hard discs which has valuable 3 TB of data. I do not want to anticipate this kind of crash issue in future. I wonder what would be safer way to store valuable data, videos, audio file etc without paying lot of money for online solutions. Shall i buy one other external hard drive and backup there for safe side. One challenge is when i connect 2 external hard drives to my 4gb RAM windows 7 laptop and tying to copy paste the data it is not copy pasting the data. I have to do small bits and pieces of 3GB of folders one at a time which takes long time. Please advice.
