Corrupt iPod file

I've had this happen twice now and can't figure out what's causing it, so I'm hoping someone else has suggestions. When I plug my iPod into my computer to update it, an error message pops up saying that the "PlayCount" file on the iPod is corrupted and unreadable and needs to be repaired using the "Chkdsk" utility. It does seem to actually be corrupted because it will not record new play counts or keep track of those songs I've played immediately before it has this issue. Both times I've used the "Restore" feature of the iPod updater, which does fix the problem, but this isn't exactly ideal because then I have to load everything back onto my iPod, which takes quite awhile because I have a few thousand songs. Does anyone have any idea why this keeps happening so I can (hopefully) prevent it from happening in the future? Oh, and this is a recent development, too. I've had the iPod since September and the first time this happened was at the end of December and then again earlier this week, and (as far as I know) I haven't been using it any differently. Thanks!

Hello - your issue appears to be related to the sysinfo error we are discussing.

General update/summary:

1) sysinfo corruption error occurs when iPods with 3.0.2 firmware connect to iTunes. Global settings are often also lost from the iPod. It is not a physical fault with the iPod or iTunes. It is a software/firmware issue. The problem seems to be affecting all iPods regardless of iTunes version or operating system.

The problem also appears to be related to a Play Counts corruption that people are getting.

2) chkdsk /f can be run from the command prompt on the iPod drive to dismiss the error message. It detects cross-linking in the file and fixes it by making an appropriate copy. However this is a more complicated solution than:

3) Other temporary solutions include soft resetting iPod (Menu+Select until Apple logo appears). Restoring also works, but takes a lot longer and accomplishes nothing if restoring back to the same 3.0.2 firmware because:

4) If a temporary solution is implemented, the problem will reoccur when iPod enters deep sleep (after 36 hrs). So:

5) The permanent solution is to restore to 3.0.1 firmware using an older version of iPod Updater. If you don't already have one, try the last available one at

6) I have reported the problem in all its detail and Apple Engineering US are investigating this matter.

7) Search the whole of Apple Discussion for 'sysinfo' and/or 'chkdsk' for further detailed information from me and everyone else who is experiencing this problem.

Will keep everyone posted with new info when I have it.

Kind regards,

Hello George,

If you are discussing the sysinfo or Play Counts error message, and the problem is located in Ipod_Control/Device then this is actually an iPod file I believe - although the error message says it is an iTunes file, it isn't - the directory iPod_Control is located on the actual iPod.

You are also correct in saying that a reformat/restore is not necessary - and a simple soft reset does the trick - that is until the iPod enters deep sleep after 36hrs as we have noted.

Restoring to a firmware other than 3.0.2 is the only known permanent way of fixing the sysinfo error (to the best of my knowledge).

All the best,

Da Gopha.

Hi George,

Sure thing - no worries. When I first saw it, I thought the same thing, but having trawled iTunes for it, I realised it was actually on the iPod.

A popular misconception - and a misleading error message. iTunes uses the control files from the iPod, and hence the error occurs only when iTunes is accessing iPod.

But it's good to get things clear - because loads and loads of people are spending ages uninstalling and reinstalling iTunes, thinking it is a problem on their computer, when actually it's the iPod that needs attention.

Kind regards,

Da Gopha.
