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.


User uploaded file


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.

thanx alot.


does it make sense that the reallocs keep going up but at the same time the pending sectors are going down? because these are my numbers after a bunch of attempts.


First attempt Second Third Fourth


retracts 13

reallocs 13216 13392 14208 14544

pending sectors 3160 2984 2168 1832

power on hours 203 204 214

start stops 25552 25561 25569 25590

temp current 35c 33c

temp min 3c

temp max 62c



P.S. Does it make sense that i cant even copy files onto the ipod in disk mode?

Nov 10, 2013 8:38 AM in response to turingtest2

i just reformatted my ipod with windows and these were my new results.


retracts: 13

reallocs: 16376

pending sectors: 0

power on hours: 215

start/stops: 25607

temp current: 38c


when i tried syncing after that it got stuck again at around the 1 GB mark. Also when i tried copying through windows explorer it also got stuck at around the same place. Now that the pending sectors are gone is there any hope. (even to just backup the files, because i dont have it backed up.)

Thanx


The fact that so many defects have been found and swapped out suggests the drive is no longer reliable. Anything you store on it may not be able to be read when you try. If you're having trouble loading data then that just adds to the picture.

Mine has decided to stop working in the last couple days too. It plays music, but whenver I tried adding new music to it, songs would transfer sooo slowly. Made sure everything was updated, still slow. Reset the ipod to factory settings, and it was doing well for a while, but by the time I reached the J artists in iTunes, it slowed down again and eventually froze. Now plugging it in says its a corrupted iPod. I look at the stats and found 130 Reallocs, 37 Pending Sectors. I think the worst part is that the max temp said 250C, which is significantly higher than anyone else's I've seen in this thread.


Tried plugging it in to run disk repair/utility but its not showing up in My Computer.


Any ideas?

The 250C temp. is probably a corrupt value recorded as the result of some kind of crash. I think parts of the iPod would have melted had it really got that hot.


The counts of pending and reallocated don't seem that serious. Might be worth trying the DFU restore method from the previous page of this thread.

What does this say about the ipod because it hasn't been allowing me to restore andjf don't show up in the internet exploerer


Again I'd try the DFU restore method. It ought to sort things out.

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.


I haven't mentioned it there, but go into iTunes preferences and tick the option Prevent iPods, iPhone and iPads from syncing automatically. Close iTunes. Connect the USB cable and immediately press MENU+SELECT for exactly 12 seconds. Get the timing wrong and it starts up as normal or reboots again. iTunes should be able to restore the device if you can get the device in DFU mode.

Is the hard drive dead?

Since i restore the IPod and i always get this image: Do not disconnect and ok to disconnect screen. Can't access to the main menus even the ipod isn't connected to the computer.. Any solutions? Btw I already tried to format and nothing.

Jan 6, 2014 2:52 PM in response to Bongo73

hello,

I don't know if my problem is the same of yours but I try to explain.

I have iPod classic 160GB using both Mac and Windows.

Because a Windows crash (what news ?!?) my iPod seems crazy.

When I connect it to Windows, everything crashes.

In Mac is different: a lot of time iTunes says "Verifying iPod...". In iPod display there's always the sync logo with written "Syncing. Do not espell" nothing changes.

I've tried to connect it normally, in Disk Mode; I've tried all the diagnostics in this thread and these is my results:

Retracts: 64

Reallocs: 2

Péending: 3

PowerOn Hours 846

Start/Stop: 1030

Temp: current 29°

Temp: min 3°

Temp: max 53°


I've tried also the 12 seconds DFU restore. Nothing.

I've also tried to restore with iTunes but nothing. The program says something like "Impossible to restore iPod because it's impossible to disable".

I've tried analyze/repair with Utility Disk buth nothing.

I've tried restore/disable/format with Disk Utility but nothing.


The greatest thing is that I CAN listen iPod. Works perfect. But I can't add/remove/menage from iTunes.


what could you suggest ?
