File transfer stuck at 0 bytes while moving a game from HDD to SSD

Check both drives for errors, especially the older HDD. A drive can still run games normally while developing slow reads or bad sectors, which can cause a large transfer to stall. If the copy failed partway through, you can usually resume by copying the remaining files into the destination and choosing to skip or replace files as appropriate, but verify the game afterward.

Robocopy is a good option for this kind of transfer. It is designed for large copies, can retry failed files, and supports multiple threads. For example, you could use `robocopy "D:GameFolder" "E:GameFolder" /E /Z /J /R:3 /W:5`, replacing the paths with your HDD and SSD locations. Afterward, run the game’s file verification tool.

Try transferring the game in smaller sections instead of moving the entire folder at once. That can make it easier to identify a problematic file and may prevent the transfer from appearing frozen.
