I have a 2tb flash that I'm trying to copy files from a 4tb ext drive. It got unplugged during a copy and now has some problems. So, I want to back up the info and format that drive and put it back. Something went wrong. First of all, while transferring, it was only copying at about 5MB/s. All in all, it's about 1.5tb. Something went wrong again, and it stopped. I go to format the 2tb drive and start over and I'm roughly 12 hours into it and the progress bar is about 10-15% and in the last 3 I don't think its moved. I can't seem to win here. I have about 2tb of video files I've been compiling now for more than 10 years now. I don't have the time, bandwidth, or data to start this over. What would you all do? Any and all advice is greatly appreciated.
