Bad Clusters on iPod Nano

(1/2) > >>

danspam:
I have noticed that several times when I have my ipod connected to my computer (xp) and reboot, XP considers the ipod 'dirty' during boot-up and scans it for errors, usually finding bad clusters.

As this has happened a few times now, I am wondering if anyone else has noticed this and if so, does this suggest there is something wrong with the disk read/write in Rockbox which may cause the bad clusters?

mightybrick:
Rockbox has no involvement in the communication between your ipod and your computer.  Rockbox hands USB duties off to Apple's diskmode at the moment.  If problems exist with this, you could try contacting Apple.  I personally have never had this problem with my iPod (nano).

danspam:
You misunderstand me. I was not talking about the communication between the computer and the ipod, I was talking about the fact that there were bad clusters on the ipod.

Do you actually ever write to the Nano's disk with Rockbox?  

FWIW bad clusters are a common problem with FAT32.  Often it means that you shutdown the computer, or the battery died while the FAT was in an inconsistant state, not that theres a serious problem with the disk.  I'd probably just disable checking the disk, or not boot up with it plugged in.

danspam:
The last bad cluster was in a bookmark file. I should think that rockbox writes to the disk everytime it saves a config file or a bookmark. Mine auto saves a bookmark when I shutdown whilst playing music so that it can resume when it is rebooted.

I realise that FAT32 is prone to bad clusters and have experienced them before on other disks. However, I have never experienced them two or three times a week.

Perhaps one or two other ipod owners may want to scan their ipods to check for bad clusters. If it is only me that has this issue, I know its not the OS.
