May 9, 2013 3:08 PM in response to Bongo73by turingtest2,★HelpfulHere 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 50cTake 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.

May 11, 2013 11:36 AM in response to turingtest2by goose191919,Here are my stats:
Retracts: 11
Reallocs: 0
Pending Sectors: 8
PowerOn Hours: 2732
Start/Stops: 36783
Temp: Current 27c
Temp: Min 1c
Temp: Max 55cSame problem, ipod classic 80gb from 2007 and I have never had problems with it until itunes was updated. I reinstalled an older version of itunes (10.3.1.55) but it still freezes whenever I plug in my ipod. The ipod itself still works when I use it but there's no way I can add music to it now because of the freezing.
Is there anything else I can do or will I need to reformat the whole thing?
-
May 11, 2013 12:58 PM in response to goose191919by turingtest2,Max. temp is a little high. The chances are that iTunes wants to read something in those pending sectors which is why it freezes. Restoring or reformatting the drive should free those up to be replaced with more reliable ones.

May 11, 2013 10:58 PM in response to turingtest2by goose191919,Is there anyway to delete the pending sectors? I don't really want to reformat my ipod and lose all that music :/
-
May 12, 2013 3:10 AM in response to goose191919by turingtest2,The pending sectors can only be released if the file or folder they are part of is deleted, Since there is no way to get that information deleting all data is the only realistic approach. You should have copies of all media on the device in your library, and that should be backed up too.

Jul 30, 2013 7:03 PM in response to turingtest2by SJaneway,I have an ipod classic that is a few years old that keeps appearing as corrupted.
These were the stats I got:
Retracts 4
Reallocs 2848
Pending Sectors 0
Power on hours 123
starts/ stops: 11004
temp: current: 32 degrees c
min: 0 degrees c
max: 53 degrees c
When I did it a second time after trying to restore again the only thing that changed was starts and stops (to 11011)
Should I be replacing it or is it still fixable?
Thanks

Nov 9, 2013 8:08 PM in response to turingtest2by massroadtrip,these are my first stats these are my second
retracts 13
reallocs 13216 13392
pending sectors 3160 2984
power on hours 203 204
start stops 25552 25561
temp current 34c
temp min 3c
temp max 62c
what do you suggest?
my ipod was working fine until it got synced by mistake, and i lost all my music. When i tried syncing to my library it got up to 10000 songs and then it froze. this happened a bunch of times ,freezing at different points. i tried to only copy 50 songs at a time, but after 300 songs it started going slow again.
P.S. will apple replace my ipod? (im still within the first year of buying it)
Thanx alot

Nov 10, 2013 3:01 AM in response to massroadtripby turingtest2,Max. temp of 62 suggests you've let it get too hot at some point which may be the root of the problem, or it could be a symptom of the fact that the drive is having to work too hard to retrieve data. I can't answer for Apple, but it isn't likely to make a spontaneous recovery. I guess you could make an appointment with your local Genius Bar and see what they say.

Nov 10, 2013 5:31 AM in response to turingtest2by massroadtrip,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 8:03 AM in response to massroadtripby turingtest2,If you're struggling to add data via Windows Explorer after a restore then I think the drive is shot... Restoring should release the pending sectors for reallocation. Either they're not all being released or new ones are being detected almost as quickly as you can clear the backlog.

Nov 10, 2013 8:38 AM in response to turingtest2by massroadtrip,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.)
-
Nov 10, 2013 8:57 AM in response to massroadtripby turingtest2,If you formatted the device any files stored on it are gone.
The first step in my initial post advices you to recover your media from any manually managed device.
