Cannot use WINE with WINEPREFIX on mounted external partition (NOT main block device)

[succodifrutta]

Are there some bugs / limitations when creating and running wine if the prefix resides onto an external mounted partition?

I also have problems onto NTFS partition:

I think windows_names in the mount options in the problem here, since it forces all folders you create on the partition to comply with the windows rules of which characters are not allowed in file/folder names.
And that causes issues with wine, because in order to fully work wine needs a folder/symlink called c: as virtual main drive, but since windows uses ":" to separate the drive letter from a path this character is not allowed in folder names, so wine can't create that folder when creating the prefix.
To solve that problem either remove windows_names from the mount options or create the prefix on a different partition (or in case you use proton via steam replace the compatdata folder in the library on the ntfs partition with a symlink to the compatdata folder on the main partition).
