Archived - iPod not recognized correctly on Toshiba laptop

This article has been archived and is no longer updated by Apple.


If you have a Toshiba portable computer and connect any iPod model to it using USB, you may experience any of the following issues:

  • iTunes for Windows doesn't recognize your iPod.
  • Windows and iPod Updater recognize your iPod, but you get an error when you try to update or restore the iPod:
    "Firmware update failure, Disk write error"


If you encounter any of these issues, try the following steps to get your iPod working again. Important: Do not follow the steps in this article if you are using a desktop computer with only a USB keyboard and mouse. This may completely disable USB access and cause you to be unable to use Windows after restarting.

  1. Quit iTunes.
  2. On the Start menu, right-click on My Computer.
  3. From the shortcut menu, click Manage.
  4. Click Device Manager.
  5. Double-click Universal Serial Bus controllers.

  6. Right-click on any item labeled "USB 2.0," "enhanced," or "high speed," and from the shortcut menu, click Disable. Repeat for all other high-speed USB items.
  7. Restart the computer.
  8. Open iTunes.
  9. Restore your iPod.

Re-enable high-speed interfaces

After restoring your iPod, you may want to re-enable your high-speed USB interfaces. This greatly increases the speed at which files are sent to iPod. If you run into any issues after re-enabling your computer's high-speed USB interfaces, you may need to disable them again.

To re-enable your computer's high-speed USB interfaces:

  1. Open Device Manager and re-enable the options you disabled in step 6, above.
  2. Restart your computer.
  3. Open iTunes.
