iDisk Sync: Data unexpectedly appears to be missing from your iDisk

Resolution

To help avoid this issue, update to Mac OS X version 10.5.8 or 10.6.2 or later.

When syncing your iDisk, you do not see a copy of the data as it exists on the iDisk server, rather you see a local copy of that data. If you have iDisk Sync on but it's set to sync manually, your local iDisk could be out of sync if you do not manually sync it. To set up automatic syncing, open MobileMe preferences (in System Preferences), click the iDisk tab, and make sure the Update selection is set to Automatically.

To see if your data is still on the iDisk server:

1. Go to http://www.me.com.
2. Log in with your MobileMe member name and password.
3. Click iDisk.
4. Locate your desired files.

If the files are available on the iDisk server but not on your local iDisk:

1. In the Finder, choose System Preferences from the Apple () menu and then click the MobileMe icon.
2. Turn off iDisk Syncing, wait for iDisk Sync to turn off completely (the MobileMe iDisk preferences will indicate this by the iDisk Sync button showing "Start").
3. Restart your computer.
4. Connect to your iDisk in the Finder by choosing Go > iDisk, then click iDisk in the Sidebar, or use your web browser to view it at www.me.com/idisk.
5. Back up any files that are important to you. See this article for more information on backing up your files.
6. After you have disabled local iDisk Synchronization, be sure to check the Previous local iDisk image (which will appear on your desktop) for any unique files you wish to keep. If you have other Previous local iDisk images, be sure to check their contents as well. After you have found any missing files and backed them up and you want to continue using iDisk Sync, turn iDisk Syncing back on.
