Collect Files and Copy to New Location not working

I’m extremely frustrated.

I have a nearly two hour film that I’m trying to copy to an SSD for the colorist. The footage is RAW 4k, so very big files. The complete project is almost 7 TB but I assume the timeline that I’m transferring is a fraction of that.

I’ve tried to copy the files with the Project Manager twice now. The first time, it simply copied over all of the proxies over about two hours. It said that the original media was offline. So, I detached all proxies and relinked the original footage.

The second time, it went through the “Analyzing” phase fine, and went along with the copying phase for a while. But at about 40 percent, the progress bar got stuck. I decided to leave it for as long as I could, but it didn’t move for four hours!

When I finally cancelled, I checked to see if there were any new error messages. But there was nothing. Then I checked the SSD, and NOTHING had transferred over in all that time! Unlike the first time there wasn’t even a folder there to mark any progress whatsoever.

What could be wrong, given no error messages or anything? The files are showing up in the project, so they appear to be linked (even though they’re huge and the project is very slow and jerky now). The file names are the same as the proxies, so I don’t think there’s anything weird there.

I don’t even know how to figure out what’s wrong. What can I do? I have very little experience. I can try to figure out which specific files are in my completed timeline (how do I do that easily?) but isn’t it better to only copy the relevant parts of those files through project manager? What do you recommend???
