Ipod nano:ipodpatcher -w gets I/O device error and partial writes/I/O problem

Hi I’m desperate!
I get a fatal error when and partial writing when I try to write the boot information to my ipod nano.

If I haven’t misunderstood I can’t disconnect the ipod from my computer or shut the computer down until it has been resolved.

This is the printout I get:
C:\>ipodpatcher -w 1 rockboot.bin
ipodpatcher v0.3 - (C) Dave Chapman 2006

I can say that I have an USB 1.1 interface connected to my nano and
I recently uninstalled itunes and other such programs from my computer

I'm grateful for all help!

I got that I/O error when I tried formatting my nano. I was using a USB 2.0 pci card, solved it by plugging it in to the motherboards USB 1.1 plug. Seems youre already using it though.

Might be worth doing the following though. Make sure your nano is plugged in, (if using XP) right click on the My Computer, click Manage, have a look under system tools, then click the Event Viewer. Choose the System (i think, could either be the Application). Are there lots of error entries saying something like Paging Error?

If so, you may have faulty USB drivers. Try reinstalling or change to a different USB plug. Try a v2.0 as you seem to have already tried 1.1.

Good luck.

Hi all and thanks for the hints ipodfoo!
This is what has happened since last...

I got the writing done and the rockbox files installed… But I putting music files fails randomly and repeatedly.
I will tell you the story...
First I can say that I use Win2k.

I tried to eliminate errors:

*My explorer.exe shell had given me problems for some time by crashing locking files and such. So I downloaded and installed blackbox for windows (bblean). I’m not totally satisfied with the appearance. But just started and haven’t modded it yet.

*My nano wouldn’t go into diskmode by pressing the key combination since it got screwed up by the partial writing (I think). So I couldn’t access it. But sometimes after uninstalling it in the device manager it went automatically into diskmode when reconnected. But just for a while after that it booted to the playing screen.

*I found the event viewer was full of reports of paging errors.

*So I downloaded a shareware from tucows called “USBinfo” to run diagnostics on the connection.
When I ran the program and connected the nano to the port I got it to stay in diskmode.
So I thought why not try ipodpatcher -w 1 rockboot.bin. It worked!
I also got the rockbox program in to the root.

*But when I tried to transfer music files it didn’t work.
I tried to transfer from an other computers USB-port (version 2 also on a laptop) as well and there it didn’t stay in discmode for more than 10 seconds.

*I looked in my device manager and according to it I have under USB:
 Intel 82371AB/EB PCI to USB Universal Host Controller
and
USB Root Hub

I downloaded a program from Intel that identifies my chipset gave me this:

Chipset
Intel(R) 440 chipset family
Detected Chipset:
Chipset Components
Memory Controller:       82443BX/DX/ZX
I/O Controller:               82371MB (PIIX4M)
Integrated Graphics:     Not Detected or Disabled
Utility Note
If this chipset information differs from what was expected, please contact the
system manufacturer or place of purchase.

I believe the 82371MB (PIIX4M) is my USB controller.
I don’t find any drivers out there for it. I tried the generic USB controller and I still get random errors.

*But I can transfer files through the USB to my Iriver DAP without problems… Still my Iriver doesn’t sense when it is stopped in windows. But it does that on many USB ports.

I don’t know what to do.
Can it be the cable?

nuss75:
I forgot to say that I have used the
“Intel(R) Chipset Software Installation
Utility.  This utility will enable Plug & Play INF support for
Intel(R) chipset components”.
It is supposed to fix the problems with the usb-driver.

And reinstalled the usbdriver from windows update...

iPodFoo:
Maybe you should try a new cable. You need to be able to have the Nano plugged in and not get those paging errors ideally. Double check the Hardware Devices for yellow exclaimation marks too.

You dont say clearly if youve tried it on another PC? Try that next if you havent.

Not too sure why its not staying in diskmode. Could be a lack of power through the usb or again, could be the cable. Are you definately pressing the Menu and Select to reboot and HOLD down the select as you quickly press the Play button as soon as the apple icon appears? I noticed you have to do this if you use apple firmware 1.2.

You need to really sort out the paging errors. The fact you had "My explorer.exe shell had given me problems for some time by crashing locking files and such", seems like an internal XP problem there. Maybe a reinstall or repair of that. Search on computing.net to possibly find a fix.

Sorry if a bit long and not really an answer, but give them a go. Let me know how it goes.
