If you restored from backup and still have the problem try restoring to factory settings/new iPod.
If you then still have the problem that indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Thanks for the response. I'll try that next time. I don't currently suspect a hardware problem because between the occurances the device worked fine and all of the media was accessable. As a precaution, I've disabled the WiFi synch just incase it was somehow getting interupted when not tethered to the PC by the cord. If there was an interupted synch, I'm not sure why that would cause 35 GBs of content to vanish, but I did that as a precaution.
I'll keep an eye on it. If it happens again, and your solution works, I'll be sure to come back and give you credit .

5 days later. Wifi sync is still off and no more problems yet.

I don't think WiFi sync has anything to do with it. I turned it off shortly after it was first introduced in what, iOS 5? Anyway, I detailed what happened to me last night in this message:
I'm still running iTunes 10.6.3.25, so iTunes 10.7 isn't a requirement, either. Besides the Touch spontaneously losing all music, the things we have in common include 4th gen Touch, iOS 6, and not connecting to any new computers, just the regular one.
Anyway, as I described in my message, I was able to get the syncing working again by turning off the syncing of music, syncing, turning music sync back on, and syncing again. I didn't lose any more data or settings this way.

I've had this happen to me (iPod Touch 4G 64Gb, iOS6, iTunes 10.7.0.21 on Windows 7 Pro), at least 3 or 4 times now since upgrading to iOS6... each time, I've had to go through several synch cycles (checking and unchecking synching of music, etc.), and have seen the storage bar go up/down in iTunes weirdly as I check/uncheck things. It just happened to me again, which prompted me to check to see if anyone else has had the issue - clearly I'm not alone.
This is particularly painful to me, as every time it happens I have to re-synch about 40GB in music and podcasts, which takes a long-*** time. I'm not doing anything different than I have with previous iOS versions, I don't use wifi synch with the iPod (I do with my iPad though), this is definitely some sort of weird bug. I think I remember seeing some evidence or mention of it possibly being related to voice memo recordings, but I haven't figured anything out yet.
This along with the Podcast app/Podcast playlist thing has been a fairly large pain.

I've had the same thing happen twice -- once this past Spring and once today. I can reload everything but it takes quite some time. I'd like to know what's causing it & how to avoid!

I just had this happen on my 64Gb iPad (3rd Gen) for the first time - as noted above, it's happened to my 64Gb iPod Touch (4th gen) several times. This is really ******* me off, as it takes a long-*** time to recopy 40Gb of content FOR NO GOOD REASON. Apple? Anyone?

Apple has just released iOS 6.0.1. We can only hope an undocumented fix for this bug is included. BTW, if you haven't reported the bug on Apple's feedback page, please do so!

The problem had not occured since turning off wifi sync until tonight. I plugged it into the computer to sync for the first time since updating to 6.01. And it locked during the sync, was on step 7 of sync for about 30 min. I told iTunes to eject it. I tunes showed the sync had stopped, but the iPod Touch countinued to show the spinning arrows. I reset the iPod, all the music and podcasts were gone again. I tried syncing and after the sync it was all still gone. It's late at night, I don't have time to mess with this and I won't have my music or podcasts for my commute tomorrow. Not happy.

...and, this just happened to my iPod Touch (4th gen, 64Gb) for what must be the 5th or 6th time, right before heading out for a drive... 40GB of music and most importantly podcasts just vanishing off the device during a normal sync. I'm clearly not the only one suffering from this - is there a way to officially report a bug, or is this form it? This is not acceptable. Hmm, I see that jon8979 says something about a feedback page, I'll see if I can find that and figure out how to report this tonight.
Currently Being ModeratedNov 13, 2012 8:27 PM (in response to jon8979)
FWIW, 6.0.1 continues to be good for me...
Currently Being ModeratedNov 30, 2012 2:01 PM (in response to VacaBoca)
I just updated to iTunes 11, and upon first sync lost 40+GB of music and podcasts from my iPod again... pretty tired of this.
Currently Being ModeratedDec 5, 2012 9:53 PM (in response to VacaBoca)
Here's my situation:
Hardware: Apple iPod Touch 4g, 64 GB, purchased in Feb 2012. Factory installed iOS 5 (received all updates as they were released).
Computer: Windows 7 64-bit (all updates applied). Currently running iTunes 184.108.40.206.
Usage: Over 40 GB of music (all higher BR converted to 128 kbps AAC; 10,000+ songs), no videos/photos; maybe 50 podcasts. Used daily for seven months with no problems (content deleted/added/re-synced weekly). Usual total content is ~50 GB. Never a single problem with device.
Change: Updated to iOS 6.0 upon launch. Since then, iPod has never had a full sync. Adding that large volume of content takes many hours. Will sync maybe 90% of the content, then iPod/iTunes loses sync. Often has message stating iPod cannot be found. This happens whether syncing via USB or Wi-Fi. iTunes will either say iPod has original content sync'd (~50 GB) or very little content (~2 GB) depending on which iTunes tab is being looked at. However, device will have lost 99% of previously-sync'd content.
I've taken multiple steps in effort to allow successful sync. At my estimation, I've done this approximately 9 times (this includes a 3 week window where I gave up on the device and did nothing).
It's important to note that I have three 64 GB iPads which have had no problems syncing with my iTunes library - either with iOS 5 or 6. In addition, my two iPhone 4S devices have had no problems.
Remediation attempts: Ensured OS is updated with all patches. Ensured iTunes is up-to-date. Ensured updates to iOS6 have been installed (including 6.0.1). Ensured power settings on Windows do not turn off Wi-Fi or USB after specified period of time. I even checked anti-virus/firewall settings to ensure no critical processes were being blocked. Nothing has improved the situation.
I have completely restored iPod Touch 4g at least five times. I've restored the iPod multiple times AND rebuilt the sync list from scratch multiple times. Neither has had any effect in allowing a full sync.
Apple Support: I contacted Apple Support by phone approximately two weeks ago and explained the situation with them. They began to walk me through their troubleshooting process:
- Has the iPod been updated to the latest version of iOS?
- What version of iTunes are you running?
- Is the computer plugged in?
- Do you know how to synchronize content between your library and Apple device?
- Are you unplugging your device during the sync process?
After suffering several minutes of this banality, I told them this process is not solving any problems. I asked them to explain several things to me.
1) If I used the device successfully for 7 months without issue, why would I suddenly forget how to use iTunes or the iPod at the exact moment iOS 6 was installed? Why have I not forgotten how to use/sync the other iOS devices?
2) If there is a problem with my computer settings / hardware / firewall / etc., why is this only affecting the iPod Touch 4g? Why not the 3 iPads? Why not the iPhones? I have a mixture of iOS 5 and 6 on these devices and have no problems whatsoever.
My position is that I do not want to mess around with computer settings/troubleshooting with them for hours. I've spent enough time on my own working on the problem and I am tired of it. I paid $360 for the device, and it worked flawlessly until their software update was installed. Now it is broken and doesn't work. I have spent decades building computation devices and tweaking software and now I spend all day putting my engineering degrees to work on much larger technical fixes. I thought the selling point of Apple products is that they "just work."
I told the Apple Rep I want a refund (I'd rather get a new iPod Touch which is hopefully designed to work with iOS 6 than continue trying to keep a previous-generation device alive). They said they would refund my money if I had bought it through Apple, but they would not since I bought it through Amazon.com. Their comment was that they don't know where Amazon might have procured it. This sounds like B.S. to me, as each device has a serial number and they know when each one is activated. Doesn't make sense.
In addition, they claimed they never heard of iOS 6 problems with iPod Touches. When I pointed out all these entries on their own website, the individual said "well I've never seen it personally." So the most cutting-edge technology company in the consumer electronics industry relies upon the personal experience of each phone jockey to provide their own knowledge of a product's problems. No internal product bulletins?
In all fairness, they offered to exchange it for another iPod Touch 4G (refurb special, no doubt). But with these systemic problems I read about with the iPod Touch and iOS 6... I don't want to mess with it. I have a lot of disposable income and would rather re-direct it to companies which stand by their products and don't release half-baked OS updates. If iOS 6 was incapable of being ported to the iPod Touch 4G, they should have left if off the upgrade roadmap.
Sorry for the long message, but hopefully someone out there can recognize common threads and we can put together enough proof that this is a real problem. Instead of having Apple deny there is anything wrong (except user error or running iTunes through a Windows OS).

Just happened to me again. I posted feedback via iTunes, and linked to this forum thread in hopes of getting some actual Apple attention to this issue.
