Details

iPod video 30gb freezes after some time of HD-action. (connected via usb-cable)

When trying to copy a large amount of (ogg)-files (10gb) from iPod to PC, then the iPod freezes after having copied about 2.6gb (~190 files)and any program you used for that action shows a read-error.
After resetting the iPod you can continue normally, until you have the next freeze again at about the next 2.5gb... same procedure, reset, continue copying, next freeze... and so on.
The AppleOS does NOT show this behaviour. You can copy this 10gb without any trouble.

Next issue of probably the same source:
I tried to make an iPod Image using TrueImage 10.0 which failed with error having rockbox-OS active. No problem with Apple-OS active.
This task depends upon

Reason for closing:  Invalid
Additional comments about closing:  Rockbox doesn't have a USB mode on any iPods yet. When a USB cable is inserted, Rockbox resets and loads diskmode which is handled by Apple's firmware. If you are having issues with freezes in diskmode, Apple OS is to blame - Rockbox isn't even running.

Pasting in the Request for Reopen comment by ClausM (ccrider):

Requested task to be re-opened - I think it MUST have something to do with rockbox-OS. The freeze ONLY happens when ROCKBOX is running ! The same action in Apple-OS does not cause the ipod to freeze. I switched between them about 20 times... and in rockbox the described action ALWAYS freezes the ipod, in aplle-os it NEVER freezes. In addition... I'm not quite sure about using apple usb-mode in rockbox. Why then do I just get half usb-speed in rockbox compared with usb action in apple-os ? (iPod -> PC)

This bug is definitely *not* rockbox related. During USB access rockbox isn't running, hence it cannot be the cause for the problem. Rockbox reboots into Apple disk mode when it detects an USB connection. It must do so because the iPods handle USB in software, and rockbox has no USB stack yet. So your problem is obviously that the diskmode rockbox can reboot into (the so-called emergency disk mode) has a bug. Nothing we can change... It's also known that emergency disk mode is slow on iPod Video and Nano.

Yes, the the iPod resets itself when entering Disk Mode from Rockbox, thus, clearing any instance of rockbox from the ram, so it can't have anything to do with Rockbox. You may want to email/contact Apple about this, as it is their problem.

In the email, you must refer to "Disk Mode" as the mode that causes the freezing, not Rockbox. They are separate entities
