How can I be certain that each file is copied correctly when moving a large number of important files, such as photos and videos to a new hard drive?
thanks for the answers. very helpful!
Just get the MD5 sum of the folder/contents and compare it to what should have copied. If they match, they copied correctly.
There are some file copy software that once finished the job creates a log file.
you can also create a file liste from the files thar are copied on hard drive so tocheck it.
