160Gb makes it some flavour of the 6th generation.
*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 for my 2 year old 6th Generation Classic:
Pending Sectors: 0
PowerOn Hours: 2202
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.
I've obviously no idea of how carefully you've looked after your iPod but you should be aware that the hard drive is a fragile component. Drop the iPod with too much force, or once too often, get it too hot, too cold or wet and it is likely to die. The 12 month warranty is usually enough to cover any product that was sub-par at the time of manufacture. You would probably have had an option to take out an extended warranty (at a cost) when you purchased it. Personally I always think such things are poor value for money as I'm more likely to have an accident with it which I can't claim for than a slow-burning defect which I can.
I have a ipod classic 80GB
I am having the same problems but what do you do after you do the manual test? my numbers where
Pending Sectors: 3256
PowerOn Hours: 337
Temp: Current 33c
Temp: Min 5c
Temp: Max 53c
and after trying to update it again they stayed the same. so what now?
My Classic iPod also have the problem that error 1439. Then I checked in \HDSMARTDATA
I got the result here:
Pending Sectors :35
Power On Hours :748
Start/Stops : 1907
Temp : Current 31 C
Temp : Min 24 C
Temp : Max 45 C
Then i reset my ipod and made the disk mode again. And connected to my PC and restore it. Then iTune said ipod is restarting and it will detect ipod after restart.
After restart, iTune doesn't recognize ipod. but I can enter to my iPod.
How should i do to recognize my ipod from itune?
Now my itune detect my iPod.
I checked the iPod properties.
Ipod right click > Properties > Hardware . Then at all disk drives, select the Apple Ipod Drives and Click properties again. Ipod Properties appear and go to the
policies tab and click Restore defaults button.
After that, my itune detect ipod.
