Comment 9 for bug 125887

I can say that the situation is "sticky".
That is, once gedit alledges that the file was externally modified, it will continue to do so if one selects "Don't save" and tries to save again (and again).
This said, I investigated a case and I attached a log showing :
- the time and time stamps of the file -- named servers -- and its backup
- that the file had not been touched for more than 3 hours since gedit had saved it last and kept in memory (editing)
- that I made a copy t of servers before I "so dangerously" saved it
- that the diff between t and servers was removing a few null lines
- that this is exactly the modification I made to servers before saving it
- that, hence, the contents of server had not been changed despite what gedit says

I just figured that a similarity between FAT32 and smb is non-Unix timestamping.

Hoping this will help.
André.
