Funny enough, the partition with the data is already on the NTFS partition as it was used with a windows install (I am dual booting although haven't booted windows since finishing setting up Ubuntu in January).
Another note on save error, it will happen when exiting a file if the document prompts you to save it and you agree it will once again crash.
This seems to generally happen after a period of time of the document being open. Not sure if its related to the PC going to sleep.
There is no error report, just says word/excel experienced an error. Would you like to repair the installation. I wounder if its not really related to saving but something else, almost seems similar to the unlicensed product error issue I had before (once you get unlicensed product error, you can't save the document, but it does not totally crash)
EDIT: I am now 100% convinced it is contniuation of same issue as described in this thread
Basically after period of time word and excel will think they are an unlicensed product, at which point you wont be able to save the document, in earlier version it would actually throw up an error explicitly stating so, now it just crashes.
This is rather irritating issue that needs to be really solved, as this requires you to save the document almost every min or risking loosing all work (no recovery data is saved either)
