For the last several years,I only use Western Digital.All the other brands,that I have tried have failed.A type that relied on a power cord failed in less than a year. I dedicate each drive for specific stuff & or particular windows. Like 7 VS 10...I have rescued most of my audio cassettes,LP and CD`s and have the wav files on them. I do not trust leaving stuff on a internal drive. If,a download works or solves a problem,I leave a copy of the file on a WD drive.A few,I do selective backup. I will never save stuff where Microsoft try`s to force you save stuff.
