Comment 4 for bug 248659

The hidden found.000 directory is created when chkdsk is run. Whether you can recover any useful information from there depends on the damage. From the reports I received in the past, usually you can restore the files therein and then boot Wubi, but your luck may vary. Unfortunately there is little we can do on the Linux side once you have filesystem corruption in ntfs, other than informing the user via a panic message. At the moment the only way to fix things is by running chkdsk (or equivalent) from windows, and that might in some cases hide away the files. Hopefully fsck for ntfs will be available soon. If you have any suggestion, please post it.
