This sounds like a typical permissions problem, I guess your apache user doesn’t have the necessary write permissions on the new data folder, potentially because the owner is wrong. You should be able to use the commands chown (to change file/directory ownership) and chmod (to modify read/write/execute [or list directory content] permissions), to set this right and ls -l to see the permissions. Documentation on how to use these commands is widely available, a good starting point is always a man page.
A nice trick with chown and chmod is to use --ref. Then you don’t actually have to know the permissions or users, you can just point to a folder/file which already has the correct permissions.

Some more info on the external drive would be interesting as well.

True, you will have problems on a NTFS formatted drive as it doesn’t support POSIX file permissions.
