I've got an external 500gb Seagate drive with 2 journalised partitions.....one for my time machine backups and the other for holding audio samples for my drum machines and such. All of a sudden today the audio partition won't mount but the time machine partition still works fine. I go into disk utility and it shows ther but just says unable to mount when I try to mount it. It suggests first aid so I verify and repair numerous times and it says everything is ok. I can boot up Ubuntu in VMware andboth partitions are visible and all the files are there....everything is just as it should be. I was using 10.5.7 and just upgraded to 10.5.8 tonight and nothing changed. I can't find any help that worked in my googling research. Please help!!!! BTW this drive and these partitions have worked for over a year with no issues.....I made no changes to prompt this.....wasn't using the audio files on the drive or anything.
