How To Fix A Corrupt iPod

Okay, this is my first and possibly last post here, I just thought that I should write my solution to this problem as there are a lot of people suffering with a corrupt iPod. I will first recommend you read this topic also if you're still having problems

http://discussions.apple.com/thread.jspa?messageID=3639883&#3639883

This will be a long post (sorry), so I'll break things up into an EXPLANTION of the problem and the SOLUTION as I think some people will be thankful for a bit of insight and some people just want a solution.
read on...

EXPLANATION:
My problem occured when receiving a second hand iPod, it had some bugs, stutters and general problems so I tried a restore, this is where my real problems started. After the restore music would not always copy correctly to the iPod, some times returning with a "Windows Delayed Write Failure", also some songs and videos would not play sometimes requiring a restart (reset), sometimes they would return me to the menu straight, and sometimes they would play fine. Also the hard disk would make a lot of fuss just to select certain songs or videos, I would even have trouble booting the iPod or detecting in iTunes.
These things led me to believe either: The hard disk was cactus; The hard disk had bad sectors; Or there was a file system error on the hard disk.
When the iPod got really bad it wouldn't properly detect in iTunes, iPod Access, Anapod or Windows, it wouldn't restore in iTunes, and I couldn't access it through windows explorer even in disk mode as it claimed the disk or the control folder had corrupted.
Using some diagnostic tools I discovered the problem was nothing more than a simple and easily fixed FAT32 filesystem error.
The problem is that the iPod uses a FAT32 filesystem which is a 'kind of unstable' but not yet redundant filesystem we used back in the Windows 98 days, I assume it uses this filesystem for compatability reasons as pretty much any pc with Windows 98 or above can access FAT32.
FAT32 stores files in chains, linking one file to another, and branching out like a tree, this system is very easily corruptable due to anything from bad shutdowns or yanking the dock cable of the iPod during copying.

SOLUTION:
1:(optional) Check your iPod by reseting it and when the apple logo first appears hold the middle select button and the rewind button to enter a diagnostic mode. Then press the menu button to enter manual testing. Scroll down to IO and press select, then select the hard disk option, then select the hard disk specs option. Read the data to check your hard disk is detected as the correct size (30Gb in my case), if it isn't then reset the iPod and repeat this step until the hard disk detects as the correct size.

2:Reset your iPod, as the apple logo appears hold down the middle select button and the play button, it will then boot to a screen with a tick in the middle and it will say Disk Mode along the top of the screen.

3: Now load iTunes and then plug the iPod into your computer and let it detect. iTunes should detect your iPod though it may not properly detect it. If iTunes doesn't detect an iPod AT ALL then reset your iPod and repeat steps 2 & 3 until it does.

4: Now your iTunes should display your iPod or an iPod just call IPOD, click on your iPod and restore, you can use the same version software or update - it doesn't matter. Even if your iPod normally recieves an error when retoring it SHOULD restore as long as you're in disk mode. When it is done restoring DO NOT UNPLUG THE IPOD, just let iTunes redetect it.

5: Now go to My Computer and right click on your iPod (could be called Removable Disk and go to properties. Now click on the tools tab and run Scandisk (Check Disk). In the scandisk box that opens tick both check boxes (fix automatically and surface scan) and click run, this will take a while but when it's done go to iTunes and eject the iPod, unplug it from the computer, and reset it.
You have jsut fixed your iPod.

Please if you use this solution and it works for you, post your thanks or comments so I know my time wasn't wasted writing this.
thankyou

Alright...
Assuming you've followed ALL the steps correctly and in order and your iPod still won't restore in iTunes, the only option remaining is a regular full windows format of the iPod.
1: Go to My Computer after mounting your iPod in Disk Mode (absolutely neccessary). Right click on your iPod (maybe seen as Removable Disk) and go to format.

2: In the box that opens you should see some options, UNCHECK Quick Format and make sure that it's going to format it as FAT32, then click Format. This will scrub your iPod clean, replacing the filesystem entirely. THIS IS NOT A RESTORE, you may need to unmount and reset your iPod into regular mode when this is done, but I'd probably just skip resetting it and go straight into iTunes.

3: Load iTunes and plug your iPod back in to do a restore and get the iPod up and running again.

IMPORTANT NOTES:
1: I never mentioned this in the main post because it should be an absolute last resort. Having your iPod's Hard Disk running constantly for as long as it takes to do a full format can slightly reduce the iPods lifespan, but if it's necessary (and only when necessary) I can't see the harm. The same goes for a scandisk surface scan. The iPods hard disk isn't made to be running constantly so bear that in mind.

2: All things don't work for all people, the only way I can make a clear & concise guide is by getting as much detailed feedback as I can, so if this works for you or not, I'd like to hear from you.

3: An iPod hard disk like any hard disk is still prone to bad sectors (rare as they are). Distinguishing the difference between a filesystem error and some bad sectors on a corrupt iPod is a job in itself, also bear that in mind.
Good luck!

Odsmart (or anyone else that can help me). I have tried everything. My iPod comes up with the message "Attempt to copy to ipod failed, unknown error. (-69)" My ipod seems to work fine when it's not connected to the computer, but when I try to put music on it from my itunes, it displays that message. My computer recognizes my ipod, itunes works fine, and there is no physical problem with the ipod, but I just can't put music on it. I tried all the tests that you have posted, I tried resetting it, I tried restoring it (even in disk mode), I tried the disk error checking, I tried formatting it. I know there has been alot of time spent on helping people, and I am very grateful for that. I have spent lots of time trying to work on this myself, but nothing is working. Please help me if you can. If you need any more information let me know. Thanks.

Hey x i really dont understand and i was wondering if you could do one more bit of advice!? When i put it on the hardspecs info itz comes up with "Model Number= " then the rest is blank. I really don't know what to do. So confusing. I have tried reseting aswell but that doesnt work either. I live in Portugal and i am Englsh, so if there was any ipod help desks i wouldn't beable to talk to them. I just want my ipod to work! =(

Odsmart,

Well thank god I'm talking to an expert now! The symptoms you describe are exactly what's been happening to me.

I've tried your first set of instructions and I got some differences;

1. Couldn't seem to get into the diagnostic mode at all, but as that's optional didn't worry about it.
2. After doing the restore in disk mode, iTunes didn't show the iPod as mounted.
3. However, despite point 2, explorer could see the iPod so I went ahead and did a scandisk (still in disk mode).
4. It took around 2hrs which worried me, but I let it run rather than stop it.
5. Right at the end of the scan disk, when all the green bars were full, I got an error message saying couldn't complete operation (sorry, didn't write it down). I was gutted. I had to manually eject the iPod via windows.

This doesn't seem to have worked yet. Still getting problems mounting etc. However, I'm to try another scandisk, this time with it showing in iTunes (reckon I'll get it to mount at some point) before I try the format option which seems to be the last resort.

Not there yet, but thanks a lot anyway!

Not sure if anyone's monitoring this thread anymore...

the scan disk didn't work for me, got an error at the end and repeated efforts keep getting same error.

So, thought I'd try the full FAT32 re-format. However, when i get the format box up, there's no data in the File System drop down box, or the Allocation Unit Size box. Can I just go ahead and re-format and assume it will pick the right file system.

hello oddsmart... ive been reading your posts and it looks like you know what you are doing. I have spent hours on my ipod and am extremely frustrating. I have had ipods since they first came out 5 years ago and this is the most trouble ive ever had.
When I plug in my ipod it says that the IPOD is corrupt and needs to be restored. It does not recognize my "NAT'S IPOD". It says the ipod needs to be restored. I attempt to restore it, and says that there was a problem downloading the IPOD software for the iPOD, "IPOD". The requested resourse was not found. I have attemped to reinstall the itunes software several times. I am so frustrated, what should I do.
If this has happened to everyone, please respond with what you did.

My ipod has been ruined by an antivirus scan for a third time. The first two instances were solved using either msconfig or a complete rebuild of the PC. It's happened again and this time msconfig doesn't help but I'm hoping to avoid a rebuild.

It's an old ipod "with docking station", circa 2003. It shows the folder/! icon. iTunes won't recognise it despite endless repetitions of the 5 R's + disk mode and the PC thinks it's 'I drive' but even so gives an error message regarding data not being written. Suggestions?

I found the solution.

Reformatted the ipod by right clicking My Computer then Manage/Storage/Disk Management, then right clicking on the ipod's drive, then Format. You can also do this direct by right clicking on the ipod's drive in My Computer. It took ages for the right click to be recognised (several minutes at least) so be patient. And the quick format worked for me, the longer option made the PC crash.

Once formatted iTunes recognised it as an ipod and finally allowed a restore, although I had to help it along by doing the reset manually while connected.

Thanks for the informative message. Unfortunately, I run into a problem while trying step 5. Specifically, the Disk Check is instantaneous. In fact, it seems as though my computer does nothing! If I ignore this fact, and precede as per your directions, the iPOD still has problems with being corrupt. Also, I have tried performing both regular and quick formats from the My Computer menu, while the iPOD was in regular and disk modes. Any suggestions would be appreciated. Oh, and by the way, in the configuration menu, all tests pass (with the exception of the iRAM test which resets my iPOD) and the hard drive shows up at near full capacity (18GB). Thanks!
