i have 350gb of music, which media center has been happily sorting and playing. i recently upgraded from jukebox to media center 15, but it found everything, and put it all in the right place without any issue. i have just installed an additional hard drive and moved my 'music' folder to the new location instead. i told media center the new location and left it to update itself while i went to work. i've just got home to found some very odd things. most items have just moved across without any issues, however, some are duplicated, appearing in both the new location and the old one (even though those files aren't there any more) and (most annoyingly) thousands of tracks appear to have lost their tags and are all grouped together under 'unassigned'. some are whole albums, but others are just random tracks. most of the album is tagged and in the right place, but then some are missing and are in 'unassigned'. why would it do that!? media center wrote the tags in the first place, so why can't it read them now, just because the location has changed!? are those tags lost forever? am i really going to have to go through the whole list and manually type then all back in again?
