I had an odt file open (had saved since the last edit) when I lost power. This is Open Office 3.0, on Ubuntu 9.x Open Office attempts to recover the file, but is unable to do so. Opening the file directly results in 3 pages of hash marks (#) I get an error when attempting to open the file as a zip archive, as well as restarting open office and the computer, attempting to recover the file again. I saved a copy of the damaged file to a USB drive and tried opening it under windows, and tried several document recovery tools I found via google (all windows-only), to no avail.
The only thing I can guess is that power was lost during an auto-save, and I sincerely hope there is some way to recover the lost data. I do have a backup of the file, but it is a few days old, and missing about 6 pages of edits and new data. Honestly, I would like to restore the file to what the OS says is the last modified time/date (yesterday evening; the power (and data) was lost early this morning)
I tried to upload the file (58k) here, but I get an error of "Sorry, the board attachment quota has been reached." The damaged file can be found at http://www.mediafire.com/?z1mkm4jimmy
