Actually, Blizzard does not support external hard drives for the games… it needs to be an internal NTFS drive.
There are a few posts about that… on this forum and elsewhere:
So I guess you need to start thinking about moving that game (and other Blizzard games you may have) off the external drive onto an internal drive.
I’m not familiar with WoW but I would think that there’s 2 ways to do that:
- uninstall WoW from your external drive using the gear icon to the right of the Play button on the BNet App and then reinstall it on an internal drive; or
- copy/move the WoW game folder from the external drive to an internal drive… and then manually update the location of the game folder in the BNet settings. You may need to run Scan and Repair also… especially if some of the files weren’t updated.
Make sure you backup important game infos (macros, screenshots, settings (?)) before uninstalling.
