copying 500GB of data from one 2TB hard drive to another (error)
every time I try at about 10% with 8 hours remaining I get the following error message an unexpected error is keeping you from copying the file. The volume for a file has been externally altered so that the open file is no longer valid
it does this at the same file every time, if I copy all files but the one that gave the error message, the next file in line will give the same message and so on.
the two are both external drives 2TB exact same make and model from the same store bought at the same time
what do I need to do do fix this and make the files copy?
Googling the error message only brought up DVDRW related problems not external hard drive problems
