I have a 500 GB drive that is about full so I was going to get a 1TB drive and then I decided to get a 2TB so I could copy the 500 GB on to a 1 TB partition and then I was going to create 3 or 4 more partitions and copy my old drives on to them. I have retired, put I need to have access to some old files and I do not want to have 4 or 5 computers just sitting in my room. Some data was on the old file service on drives S & T, so it would be nice to have partitions S & T on the new drives.
It seems that copy and paste does not work very well if you want to copy from an active main drive. The open files do not copy.
