Error codes -6999, -48, iphone won't sync!

Hi Katy I have the same problem but I get errors when I synch applications downloaded from iTunes, it seems to be an incompatibility problem between iTunes and Windows 7 (that's sure), so far there is no solution for this issue yet, but I've tried syncing my iPhone 3GS in Windows XP and works perfectly and doesn't give me any errors or problems. Try syncing your iPhone to another PC with Windows XP and the lastest iTunes installed.

All right already confirmed, I tried syncing my iPhone in Windows 7 32bit and Windows 7 64bit with two different PC's and gives me the same errors, it is definitely a compatibility issue but in my case it shows only those errors when trying to sync the apps from iTunes onto the iPhone, along syncing other things I have no problems.

Please keep us informed about what they say and how they might solve your problem

Do you have an HP?

I had exactly this problem with my iPhone. The error messages I received were -6999 and -48 and "Could not find the required folder". iTunes kept telling me that I needed to restore the iPhone.

I was using an new HP on Windows 7 64-bit. The problem was due to the Intel chip in the new HPs and a known problem.

Solution:
A Bios Update (downloaded from the Support section of the HP website) resolved the problem, and I can now sync my iPhone with iTunes successfully

You have a P55 chipset on your HP, there is a compatibility problem with Windows 7 and this chipset. As the gentleman says below you need to update the BIOS on your machine:

This is not a P55 chipset problem only, because I have
my PC with the Intel P45 chipset and I have same problem
in Windows 7 x86/x64 also I've tried in a Lenovo R60
Notebook with the Intel 945GM chipset and Windows 7 x32
installed and I get the same errors and sync problems,
definetly this is an issue between Windows 7 and iTunes.

tonyacos did you ever try removing NOD32 Antivirus System and testing?

Please find a fix for this problem, it is DEFINITELY a windows 7 and itunes compatibility issue.

My ipod touch 2G syncs fine with my XP laptop, but every time I try to sync on my 64-bit windows 7 laptop, I get a variety of error messages such as -48, 6999, or "cannot sync, a folder was specified instead of a file".

I've reinstalled itunesmultiple times, restored my ipod, restored it in recovery mode, i've even reinstalled the ipod drivers and nothing works.

You'd think Apple would test their new firmware on all models and systems before releasing it, very annoying.

I have the same problem. I have an Intel DP55KG MB, Win7 64bit and I've been running on a new install of this since the end of October. I'm sure I installed the current version of iTunes then and had the same 3GS 32GB iPhone. Apple had me do a Restore on Thurs to fix a problem with voice command. I ran into the same problem described above, but phone support was on vacation by the time it happened. I've worked all day with phone and store support. We thought we had it pegged to simply turning off Norton Internet Security. That seemed to work fine at the store, on a secondary Win7 Installed machine that I took down. But, now the problem is back on both machines again. They swapped out my iPhone twice in the process. I'm at a loss, but will continue to keep looking. If someone gets a work around or solution, please let me know ASAP. I need this working by Monday.

Hi, I'm having e-x-a-c-t-l-y the same various issues as described by shane86 with my iPod Touch 2G 16GB on my Dell Studio 1747 (Core i7, PM55 board, 4GB, Win7 64 Pro).

Only one strange thing is that after setting up this laptop during migration from my older (Vista 32) laptop everything was running well for about 5 days in a row. Since then, everything is going down the ... as soon as I try syncing photos(!).

I'm skipping Photo-Sync temporarily now and each sync (even backup and restoring) works fine - so far.
In order to get my iPod Touch back to work I copied the whole iTunes database from my new laptop to my old one again, and kept restoring and did initial syncing until finding the issues with the photos... (I took in music, films, programs etc. step by step to sort it out)

By the way: The copying method should also work with your Outlook .pst file - just in case...

Good luck & let's hope for a quick fix =)

Well this is what I could gather about this error, in my case I can not synchronize all applications downloaded from iTunes, I have to synchronize them one by one, otherwise iTunes will give me errors in Windows 7 x32 and x64. Until now I managed to reduce the number of error messages, but still I can not remove the error messages completely, well here below is what I've done to minimize the possibility of synchronization errors:

1. Entirely Disable any antivirus resident in memory (DISABLE EVERYTHING !!!)

2. (In my case) Remove the attribute "read only" to the folder "Mobile Applications", this is where the downloaded Applications are stored in iTunes (for Windows 7 x64), this is the path :

"C:\Users\(user account)\Music\iTunes\iTunes Media\Mobile Applications"

With these simple tweaks now I can synch more than one App, but I still have error messages sometimes.

I'm not sure when it first started occuring, but I have been having the same problems for days now, with my ipod Touch 16GB, latest Firmware.

Win7(32-bit)
Intel corei7 Q720 @160Ghz
4GB
NVidia GTX260M
Laptop

Had every crash possible with regards to syncing.
But it's mainly to do with syncing music and video.
I drag one .mp3 for example from my music folder into iTunes, the file goes through, but as soon as the sync starts itunes crashes.
If I turn off the device and restart, the music is often on the ipod but it sometimes causes the apps to open then immediately close.

It crashes when I press the eject button on itunes.

It has also crashes when I restart and it asks me if i want to restore or create new ipod, as soon as i click 'continue' it crashes.

Resetting/Restarting/Restoring hasn't worked.
After a long hang it usually comes up with one of the afforementioned error messages or:

'The ipod cannot be synced. A folder was specified instead of a file'
'The ipod cannot be synced. The required file cannot be found'

This is just speculation, and possibly coincidence, but it seemed to start happening when I installed TouchDJ's 'Amidio Sync' desktop app, which allows you to transfer music to an alternate folder on the ipod... i have however removed the app and I'm still having problems.

I'm having the exact same problem and I've been fighting with it for at least 10 hours today. I've done everything including reinstalling Windows 7 on my Dell Laptop. I've reinstalled iTunes 9.0.2 at least a dozen times and have tried every kind of configuration I could think of. Bottom line is iTunes does the same thing: when I plug my iPhone in it wants to restore it. I restore it and then it always gives me Errors 6999 and 48 about attempting to copy to disk and an unknown error has occurred.

THIS IS DRIVING ME CRAZY! PLEASE APPLE SHED SOME LIGHT ON THIS!!

You can try to disable some of these anti-virus programs all your want and they do not entirely quit.

The only way for sure to eliminate the possibility of interference is to uninstall it from your computer.

I would recommend disconnecting from internet after uninstall when performing this test.

Even if you think there is no possible way your anti-virus program could be the problem test and see.

It is a simple thing to do and if it works then you just saved yourself hours of frustration.
