Recovery - external hard drive

Have first gen Apple tv with a connected external hard drive containing a lot of non itunes content.  My issue is, my external drive for my imac crashed so i lost a ton of content on that computer (most of the same content that i do still have on the external drive formatted for my 1st gen appletv).  Can i sync from the external drive connected to my appletv back to my imac? If so, can i connect it directly to the imac or sync via wifi or ethernet cord?

I don’t know if you figured it out, but the way to do it, is you have to SSH into the apple tv, then actually find the files where your content is located, then just simply copy and paste it from the apple tv to your computer, once that’s done, when you click on the content, it will ask you for your iTunes password.

Good luck
