I lost my RAID 1 setting due to changing a MB battery. Now I need to transfer all the data from one of the drives with all the info to a backup drive, then re-establish the RAID 1 and place all the data back on the RAID 1 (using 2 drives for the RAID1).

What is the best practice to follow when trasnferring large amount of data?

This is not huge, about 130 GB.

I assume have the computer fully warmed up, so no background tasks are being performed. No other programs open or running.

I don't simply want to drag all the contents from one drive to the other drive. It seems like copying small chunks at a time makes the most sense.

But, I just want to see what the accepted protocol is for copying a large amount of data.

Thanks for any input.
