turing, I believe I have posted them in this very topic, which is why I am still getting email reminders of replies. 🙂 I have resisted upgrading my iTunes lately because once I get something stable I have finally learned to avoid changes. In my case, the songs were deleted only during the sync process, and only if I had the "reduce bits to 128" setting turned on, and even then it would only happen the very first time I synced new songs that I had ripped. I even tried ripping the tracks and then marking them as "Read Only" which either (a) should have prevented iTunes from deleting them, or (b) at the very least I would have expected an error message. But no, the songs still got deleted on the first sync. After restoring them to my hard drive and removing them from my iPod and rerunning the sync process everything would work. So for a while my workflow would be:
1. Rip a disc
2. Update tracks / album / artwork as desired
3. Copy all of the .mp3 files to a "temp save" directory
4. Sync to my iPod to load the new music onto the device
5. Copy everything back from the "temp save" directory to restore those tracks that were deleted
6. Sync again
I thought there was a time / date issue because I discovered that my NAS device (from Netgear) was improperly modifying the clock for daylight savings time. I thought that since I was storing my music files on that device, and it was one hour in the "future", that the tracks were being deleted because iTunes refused to see them because their date/time stamp was off. I fixed my Netgear NAS device, and the problem persisted.
Next I thought I had fixed everything with an iTunes upgrade, but it turned out that the "128 bit" setting had been turned off during that process. I prefer to have that setting on so I can get more songs on my device; I didn't buy the 160GB model because I only wanted a few tunes, I wanted to have as many with me as I could. 🙂 As soon as I turned the 128bit setting back on, the problems came back.
So now I just leave that setting off, and I put fewer songs on my iPod.
I am running an iPod Classic 160GB on Windows. I could open a "file explorer" window and show the contents of one of the album folders, and I could watch the files disappear as iTunes sync'd them. I was going to offer Apple techs the ability to view my desktop to show them that, but it turns out that they can't do that on a Windows system, plus as I mentioned above, they weren't going to help without me paying because my hardware is outside of the free service window, and they don't support iTunes separately.
