I have just gone through this.

Do not scrape from your computer to this Recalbox via network. It has destroyed the share drive on large scraps. You must shutdown emulation station with a stop command.. But, It also failed a few times for me.

The suggestion was given is to copy all your roms into a directory on your computer and scrape on it.
After the scrape is finished, copy gameslist and media to the correct directory in your recalbox folder in the share drive.

I use R-Drive to create a backup of my Recalbox drive after I finished copying all roms and bios. I then check to see if it works (no images or box scrape done yet). Once I'm sure it is ok, I then extract the roms to my spare directory on my computer. R-Drive allows to pull files and directories onto a local drive.
I then started to scrap each rom folder and then via network, transfer the image directory and gamelist over to the share drive on the Recalbox computer. No errors, no killing the hard drive.. all works.
Once I'm sure all works good, I will then do a backup of my hard drive using R-Drive.
I have no idea if any other program works or not, but I think anything will do..
You can FTP or enable rcalbox to show up as a network drive on your computer.
