My ipod Classic 160 GB stops syncing after 30 something GBs

I have over 120 GB of music in my itunes. I have tried everything: Syncing entire music library, syncing half of it, then syncing in batches of 10GB. I always have the same problem at around 32 or 33 GBs it gives me an error message sayin smething like: cannot sync song "Whatever" error (50).


I have restored ipod many times, formatted it through windows used different usb ports, read every post on this and other sites. It is always the same it won't sync more than 30something GBs!!!


HEEEELP!!!!

Check your iPod with Diagnostics Mode

It's 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 SELECT & MENU 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.

Hello! I ran the data for my iPod and it doesn't look good 😮

However, I still want to try to make mine work!


Retracts: 27

Reallocs: 3696

Pending sectors: 16

PowerON hours: 325

Start/stops: 95223

Temp current: 31c

Temp min: 70c

Temp max: 233c


I've read a couple people have "reformated" the iPod on their computers or done a "low-level format."


What is that and how can I run that for my ipod? Is there a website or program I need to use?


Please help!

See Corrupt iPod classic for a more recent set of troubleshooting suggestions. You could try the DFU restore. Windows should be able to format the drive if it is in disk mode. That said your temperature stats would suggest something has gone very wrong at some point. The min. is obviously wrong and even if the max. temp. is an exaggeration high temps in the processor can be a cause of random processor output and if present would be likely to have caused damage.

Some history: It is a iPod 5G 30GB, I got it brand new from Apple Store online in 2006, Jan of that year iirc? It was heavy usage all the way but lovingly taken care of as much as I could. Anyhow, the hdd still died after about 4 years - lasted me until beginning of 2010. I had DIY replaced it in 2010 Sept only after months of leaving the iPod around as a "paperweight". Got the replacement off eBay for like USD48ish then incl. shipping from a China seller dealing in iPod spare parts.


Note: usage for iPod during 2010-2014 ever since replacement of original hdd was really minimal as compared to the 2006-2010 days...


Earlier this year, the original battery died too - wouldn't last longer than 15-20mins on a full charge. *whew finally lol* So I had that DIY replaced too, in April.


The iPod was working OK for 3 month-ish after battery replacement *but* recent weeks I hear sluggish clicking of hdd occasionally when powering on/off. Eeerily reminiscent of the initial hdd failure, hurhur. And sometimes during song transfer from PC to hdd, the iPod would take uber long to sync or would hang even! Hence had to Reset to get it to work...


You guys think this iPod's worth a replacement hdd (again) or could it be other components failing? SDRam and Flash tests were OK. I wanted to do a complete rehaul of the music collection in it earlier and did a Restore in iTunes (also, new PC, wanted to 're-pair' with and all that...) Well now it wouldn't be detected in the new PC nor old PC (both Windows). The Restore went OK, I was in the middle of transferring songs when the iPod hanged and after a Reset, it wouldn't be detected anymore... -_- The iPod cable shouldn't be faulty as it works with my iPod Nano on both PCs.


I really love my laser engraved iPod, it was an Apple Store online special? Free laser engraving thingy. The words I chose then still meant something to me now.


HDSMARTData:
Retracts: 231

Reallocs: 78

Pending Sectors: 19

PowerOn Hours: 1744

Start/Stops: 9052

(only these 5 entries shown)


HDSpecs:

Temp: Current 29c

Min 243c

Max 56c

(pulled temp from HDSpecs, no idea why Min/Max seems reversed but 243c is reaaaal high if its indeed Max temp...)


Any hope for this iPod/hdd? Is the hdd dead/dying again? Is the replacement battery dying/faulty? After installing it in April, it did take an overnight charge plus like 2 days of inactivity before my PC would recognise the iPod with this replacement battery.

What do you advise?

(Sorry if my post is necro-ing the thread. I read all 9 pages and ttf2 seems like a helpful and knowledgeable person 🙂)

Yea, seems like nothing else I can do but to 'call it' - 'working' paperweight status if I can help it 😟 I'll still try to get the hdd replaced. Waiting on a hdd delivery - goodness those things are relatively cheap... hurhur. From an eBay seller based in China.


But regardless, am on the lookout for a new portable music player already...


Nonrelated side note: I'll think of ya when watching The Imitation Game this year end. Thanks for your solidarity and advice 🙂
