As the title pretty much summarises, storing data in External HDD (especially the ones which require power supply) is not exactly a risk-free solution. I have burnt my hands more than once even with much reputed brands in the market. There are a wide range of issues like the HD going undetected, cannot be mounted or partition table, bad sector, wow!
I currently have all my data finally cornered to a 4TB external HD (with external power) at the risk of extinction. What are recommended ways for saving huge data locally without worrying about losing it. Is it that inevitable at all.
Thanks in advance.
PS: DvD/BluRayDs is one option for the worst case. Looking for some others too if any.
