Yes, this is just insanelly ridiculous!
I noticed that iTunes was running VERY slow for the last week or so, and then suddenly realized that 200GB of my Library had dissapeared!!!! Not just dead links in the iTunes library, they had been deleted from the drive too!
The files were on a dual redundancy NAS and no errors and no other data missing, just the ones used by iTunes. Luckily I have a recent backup and am restoring the whole direcrtory, but not sure if the same will just happen again.....
First thing I will do is disable the "sync podcast options" since that appears to be the main culprit here, but its unbelievable and unacceptable that Apple can release such a destructive version of its software! I've been in IT for more than 30 years and NEVER heard of software this bad! No messages, no errors, no indication that its even deleting the files, or why its doing so!!!
Do Apple not even bother to test their software before release now?!! It's obvious that its a big and destructive bug, since so many people have been effected, why can't you pick this up in testing BEFORE release, and not release software that just thinks it can delete our files without even telling us!
This new sych option seems a ridiculous setting too! It doesn't indicate exactly what settings on what devices it is syncing, and in particular doesn't say how it handles setting conlicts either!!!
I personally know that my iTunes auto delete settings were not at fault, and in about 70% of the podcasts, the actual subscription was deleted too! not just the files!
we idiots have given itTunes full access to out precious music and video libraries, trusting that Apple will not accidentally delte them. Well, I don't know about anybody else, but I certainly have had my eyes fully opened, and will keep a VERY CLOSE eye on this old and unstable app in the future!
