Ive tried a resst to no avail
I also tried putting into disc mode again un responsive!
can it be recovered ?
thanks
iPod classic
Here are a number of things to try...
Recover media from a manually managed iPod
What follows are tips for restoring your iPod, but if it is the only location currently hosting some of your media then the first task is to try to extract it. See the user tip Recovering your iTunes library from your iPod or iOS device for some recovery tools. Most third party tools will probably require the device to have a functioning library however the techniques outlined in the iLounge Article referenced at the end should work as long as the device still shows up in Windows Explorer or Finder.
Check your iPod with Diagnostics Mode
It is possible that your iPod's hard drive has started to fail. Take your iPod and place your right thumb on the centre SELECT button and your left on the top MENU button. Press down both thumbs for about 6 seconds until your iPod reboots. Immediately move your left thumb around to the rewind button |<< on the left and hold this down together with SELECT for a further 6 seconds. Your iPod should now switch into Diagnostic Boot mode. Press MENU for Manual Test, then select IO > HardDrive > HDSMARTData to reveal your stats. For comparison here are mine taken when my 6th Generation Classic was about 2 years old:
Retracts: 889
Reallocs: 12
Pending Sectors: 0
PowerOn Hours: 2202
Start/Stops: 894
Temp: Current 24c
Temp: Min 10c
Temp: Max 50c
Take a note of your results. When finished press MENU+SELECT for 6 seconds to reset the iPod again.
With modern disc drives sectors are no longer marked bad by a disc scan, if the SMART firmware detects a sector it has trouble accessing it will attempt to invisibly reallocate it to a spare area of the disc.
Note that I've only 12 remapped sectors and none pending. To help explain what the numbers mean here is an extract from the Wikipedia S.M.A.R.T. article:
Reallocated Sectors Count
Count of reallocated sectors. When the hard drive finds a read/write/verification error, it marks this sector as "reallocated" and transfers data to a special reserved area (spare area). This process is also known as remapping, and "reallocated" sectors are called remaps. This is why, on modern hard disks, "bad blocks" cannot be found while testing the surface – all bad blocks are hidden in reallocated sectors. However, as the number of reallocated sectors increases, the read/write speed tends to decrease. The raw value normally represents a count of the number of bad sectors that have been found and remapped. Thus, the higher the attribute value, the more sectors the drive has had to reallocate.Pending sector count
Number of "unstable" sectors (waiting to be remapped, because of read errors). If an unstable sector is subsequently written or read successfully, this value is decreased and the sector is not remapped. Read errors on a sector will not remap the sector (since it might be readable later); instead, the drive firmware remembers that the sector needs to be remapped, and remaps it the next time it's written.
Large numbers of Reallocs or Pending Sectors would suggest your drive is failing and that you may need to repair or replace your iPod. Check your stats after another attempt to update your iPod. If the numbers increase that again points to hard drive failure. While it won't be good news at least you'll know it isn't some random software problem and you can decide what to do next.
Check iPod hard-drive for errors
Assuming the diagnostics give the drive a clean bill of health it may still be worth checking the drive for logical file system errors.
Hold MENU+SELECT on the iPod for about 6 seconds until it resets, then switch to PLAY+SELECT as soon as the Apple logo appears, again for about 6 seconds to put the machine in disk mode. Open iTunes and in the Devices tab of the preferences menu check Prevent iPods, iPhones, and iPads from syncing automatically. Now connect your iPod to the computer, wait until it connects, then close iTunes.
Windows: Browse My Computer and right-click on the drive for the iPod, click Properties, then click Tools. Under Error-checking, click Check Now. Under Check disk options, select Scan for and attempt recovery of bad sectors (Optional - takes ages but a good idea if you've reason to suspect physical damage). Click Start.
Mac: Run Disk Utility / Repair Disk for the equivalent process.
This should find and correct any errors in the logical & physical structures of your iPod's hard drive. Once these have been fixed you can reset the iPod (hold MENU+SELECT) and should stand a better chance of a successful restore. It might also pay to check the status of the source drive containing your media, particularly if no errors were found on the iPod.
DFU Restore
If the device still won't restore normally try this method. Connect the device to the USB cable, press MENU+SELECT like a standard reset but keep holding for 12 seconds. The device should reboot as normal and then the screen should go blank. Now open iTunes and try to restore again.
Reformat Drive
If all else fails try Erase your iPod - The Super Fix for most iPod Problems. Basically a low level format of the iPod’s hard drive to get around whatever problems are stopping iTunes from restoring it properly.
Break up large transfers
Once you've restored your iPod don't rush to dump all the data back exactly as it was before. I have found that lots of large or complex smart playlists can sometimes trigger constant reboots or dumping of the iPod's library. In addition, larger transfers can fail leaving data in an inconsistent state. Try this technique for populating the iPod in stages.
In iTunes select the menu item File... New Smart Playlist. Change the first drop-down box to Playlist, the next to is and the next to Music or whatever playlist holds the bulk of the content you want on your device. Tick against Limit to, type in say 10, then change the drop-down to GB, and set the last drop-down to artist. When you click OK you can enter a name for the playlist, e.g. Transfer.
Now sync this playlist to your iPod rather than your entire library. When the sync is complete modify the rule (File... Edit playlist) to increase the size by your chosen amount, then sync and repeat. You can experiment with different size increments, if it doesn't work just choose something a bit smaller until it works each time. Before long you should have all your music on your iPod. Once that's done you can move on to other media such as podcasts, videos, photos, playlists, etc.

Hoping you can help me here too!
The last few days, my Ipod classic has wiped all the songs off there as it says it failed to sync. I've restored it 3 times and when it gets to about 300 songs on there, uploading gets very slow and happens again, erasing everything.
Here's my results, so any help is greatly appreciated!
Retracts:2
Reallocs: 9856
Pending sectors:16
PowerOn Hours: 447
Start/stops: 9439
Temp: Current 24c
Temp: min 9c
Temp: Max 53c
Thanks for the help - done all that now. DFU and everything. But my results are exactly the same, still got 16 pending sectors.
Is there any other way of trying to get rid of them? As I can start putting songs back on there again, but know when it gets to around 300, the same thing is bound to start happening.
So from reading this entire thread i have to assume my 2009 160gb ipod classic is poked. After ITunes said it needed to be updated in May, it kept making me restore (over 6x) my ipod (which worked beautifully before) and then when it finally did restore and sync, some of the songs just skip over and don't play. I have followed your advice here and see no numbers like mine, so thought I would share......
Retracts: 3
Reallocs: 800
Pending: 11872
Power on hours: 56
Starts/stops: 4046
apart from those all normal.
as i live somewhere that there is absolutely no apple support, don't suppose you have hardware repair manual 🙂 ah ha ha ha. if it is done, then that will end my apple relationship i think.
first
this are my results:
Retracts: 9
Reallocs: 80

Start/Stops: 25335
Temp: Current 30c
Temp: Min 8c

Actually when i tried to restore in itunes at the end appears a sign saying that couldn't be restore mis 1429...
Stats like that suggest it crashed in some fashion that caused it to write incorrect values into the CMOS RAM. Getting too hot at some point could cause this. Good to hear it is otherwise holding out.

I have an IPod Classic from 2007 that has this same problem, and I am hoping it can be fixed.
My last computer was Windows Vista, and I moved to Windows 8. The previous computer had a motherboard fail and I moved to a new computer.
I managed to move all of my library over the old iPod into a new iTunes on my new computer, and then the trouble began.
The iPod says it has 0KB free yet there is nothing on it whatsoever. When it's plugged into the computer, it just freezes up my windows (can't access it through the 'My Computer') and it freezes iTunes, or iTunes absolutely won't open at all. Then when it's unplugged, the computer goes back to normal.
I did the instructions on the opening thread, and here's what I got out of my results.
Retracts: 31
Reallocs: 0
Pending Sectors: 2
PowerOn Hours: 192
Start/Stops: 294
Temp: Current 32c
Temp: Min 20c
Temp: Max 46c
After this, I went into iTunes and checked the box to not sychronize with an iPod plugged up, then plugged it in and as it did before, iTunes froze up, however when I unplugged the iPod this time, it seemed to have read it and said the unit was corrupted and needed to be restored, however I can't restore it at all since iTunes freezes up.
I pray this thing has not been broken and is possible to fix. It's a Classic 80 gig and I know they aren't made brand new today.
It is likely those two pending sectors hold some crucial data like the root folder of the drive which is why everything seizes up. The rest of the numbers look fine. Try the DFU restore method, or reformat. If you can't get that to work ask a Mac owning friend to try restoring it if you have Windows, or vice versa.

Relived to hear that it's not 100% broken.
Tried a DFU restore this morning. Plugged it up, held in the buttons, then opened iTunes. iTunes froze as it always does, but when I unplugged the iPod, iTunes came back to normal with a screen reading that the iPod was corrupted and needed to be restored. So hopefully I'm doing something right.
I don't know anyone else with a Mac, and I don't think reformating it is possible since as soon as you plug it up, iTunes won't run and if you right click it in 'My Computer', it just freezes up that window.
You may be able to format from a command prompt (Start Menu > Accessories > Command Prompt) rather than Windows Explorer. Assuming the drive letter is E: for example you would use Format E: /Q to reformat the drive.

hi turingtest2
The stats on my iPod are
retracts: 20
reallocs: 0
pending sectors: 1
everything else is quite low compared to every one else's posts
My main problem is that I am traveling for work and don't have iTunes on my work computer, so I can't connect to iTunes at the moment. I had plugged my iPod into the tv in my hotel, however it didn't work (said something in German which I didn't understand), so I unplugged it without ejecting. Now I have nothing on my iPod. Guessing I'm stuffed until I get home and can get onto iTunes...
Thanks for for any suggestions you might have.
Hi tt2,
Plugging the iPod into my work laptop hasn't done anything other than ask me if i want to re-format it... i think not. Windows Media Player doesn't seem to have anything useful in it, and we cannot run any downloaded software without admin rights. I guess I will just have to wait until I get home in a couple of weeks and try itunes. Luckily i can get some of my music from the cloud onto my phone or ipad in an emergency 🙂... just not 5000+ tracks...
I had previously posted this in another thread, but it seems like my corruption problem is actually fairly similar to those mentioned here.
Any and all help will be greatly appreciated.
Recently (one week ago), I installed the latest itunes update on my computer, a Dell Inspiron (OS: Windows 7). Since then, anytime my ipod is connected, the contents of my ipod are deleted and I am prompted to restore the ipod.
Prior to the update, there were no issues with my ipod.
My ipod is a classic 120 gb.
I ran the ipod in diagnostics mode and the following are the results of the scan:
Retracts: 19
Reallocs: 72
Pending Sectors: 0
PowerOn Hours: 1225
Start/Stops: 21163
Temp: Current 31c
Temp: Min 57c
Temp: Max 245c
After posting this, I hooked up my ipod to my computer, and after finding my ipod as a drive, right clicked the drive, selected properties, then tools, and then, under error checking, selected scan and attempt recovery of bad sectors. No problems were found.
This problem has been very frustrating for a number of reasons.
Does anyone have any solutions to this problem or am I simply out of luck because the drive is failing?
I have an appointment at an apple store tomorrow, but am not optimistic.
iPod classic, Windows 7
The temperatures are out of whack, but that could be due to a crash that corrupted the CMOS data. The realloc and pending counts are OK. Have you tried the DFU restore and break up large transfers methods? You may also want to disable your anti-virus program while trying to update the device in case that is having an impact.

I've got an iPod classic from 2007 or 2008 (can't really remember), 80gb, and it's randomly just stopped working.
Did all the things listed in the first post, and this is what I got:
Retracts: 11
Reallocs: 1648
Pending Sectors: 312
PowerOn Hours: 4359
Start/Stops: 10253
Temp: Current 35c
Temp: Min 64c
Temp: Max 239c
I know the numbers are so out of whack, but honestly, I just wanna know if it'll ever work again or if I should just let go of it.
Thanks in advance

If you are lucky a few rounds of DFU restore or reformat might release all of those pending sectors. If that doesn't work you could consider replacing the drive. Otherwise call it a day.
