Brief Summary of Problem
Transfer of an iTunes music library from an old NAS drive to a new one resulted in message of the type “unable to connect to old NAS drive address” when trying to play music from MacBook. Attempting to add music, clears library listing completely.
iTunes library originally installed on LaCie NAS drive for wireless access via Sonos iPhone app to play on Sonos speakers. Music all ripped from CDs on MacBook where iTunes pointed to the LaCie drive.
Replaced LaCie drive with WD drive, copying whole iTunes folder across. Removed LaCie drive. Music plays on the Sonos speakers from iPhone app OK.
All music still listed in iTunes library viewed from MacBook, but attempt to play results in a message that it can’t find the LaCie drive.
Although not important for playing on Sonos speakers, attempt to add new music from MacBook resultrf in error message saying the iTunes Library.itl file was damaged, and was being replaced it with a new one. After this the listing of the iTunes library is blank.
I assume that the MacBook was initially using an old iTunes Library.itl file with an absolute path to the old LaCie drive. Would that have been copied over to the WD drive or is it on the MacBook, and is there any way to restore or regenerate a library of the music that is on the new NAS drive? (The music is only on the external drive, not on the MacBook.)
