Comment 17 for bug 1280574

So apparently, Windows and Ubuntu do not read the same data, which point at a cache somewhere not synced when shutting down.

Here are a few URL pointing at a tool from Intel to configure a SSD as a cache.

Can you use this tool to determine whether a SSD cache has been configured ? I would recommend not to change the current setting, as I do not know the consequences on the installed Windows.
