Thought I would add my experience to this thread.

I have tried all the suggestions for cleaning, removing all storage, clearing game data. One thing that did work briefly was to remove the disk from the drive, close the drive tray and listen for the laser to reset, open the drive tray and insert disk and
it worked....for a while. Only way I could even get the Xbox to attempt installing the game was to disable the auto-run in the system settings.

Bought another disk from a different store (first purchased from Miejer's in Michigan, next from Futureshop in Ontario) and BOTH have the same issues on two Xbox systems in my home (Xbox-s and white Xbox). Initially the game ran without errors on my older
Xbox but gave the disc unreadable the next time it was re-started.

No disk errors with any other game we have....other than the original skylanders game which has periodic disk read errors that seem to go away after removing and re-inserting disk.

Continue to have these issues:

- disc unreadable, Status code: 8C230002 when trying to access the game info

- installing the game to HDD stops at 47% - get a disk read error after that

Activision support offers no additional suggestions that isn't already covered in this thread. They do offer to replace the disk by mail.

What fixed it was going to System -> Storage -> System Items and deleting the Marketplace System Data as well as the 360 System Cache then re-launching the game. After that I had the option to launch the Marketplace from the in-game menu and re-download
it successfully.

Thanks for your response.

The disk is now working again, although I am well aware it is likely to fail sooner rather than later. Just to confirm that connecting it to my PC did not mean I lost all my data - this would only have happened had I set up the drive under "Disk Management"
with a new partition. Although I couldn't read the drive under Windows Explorer, I was able to use some various disk utilities that work on a physical level to do their scans rather than at file system level. HDTune for example found various bad blocks (scan
only) - after running it on my PC for a bit I backed up many of the files using Xplorer360, although I am unaware how I would ever put these files back on to a new drive should I replace it!

After all this, I put it back in the 360 and it is working again. Time will tell how long it lasts.

In the meantime, is it easy to transfer all my save game datas to Cloud storage?

Thanks

After safely removing and re-installing the hard drive, if the data is still not showing on your Storage in System Settings then it might have been wiped somehow. You can still re-download your profile and your games, but your game saves are likely gone
if they are not on the storage device. Out of curiosity what is the size of the hard drive and how did you obtain the hard drive? I'm just curious if it was purchased brand new or purchased third party.
