Fact or fiction without any friction, I have heard in passing on the web only about 2 times, that hard drives will re-write the data onto the platter when Only reading the data off of that platter.
Question applies to modern normal consumer hard drives with spinning platters, and read/write heads.
Do hard drives really re-write data when only reading data from the drive?
If i am supposed to have a specific problem, then: For very long term storage of data, if this is actually true, then reading the data once a year could insure a better magnetic polarity differance. For long term storage not only would it be good to spin it up and get the motor moving, but to do a read of the data one time.
