            Bug ID: 113138
           Summary: general input/output error on save, files truncated
                    [FILESAVE]
           Product: LibreOffice
           Version: 5.4.1.2 release
          Hardware: x86-64 (AMD64)
                OS: Windows (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Calc
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: heseltine.michael at gmail.com

I fully expect this to be useless, as I cannot give an exact way to reproduce
the error but here it goes anyway: 

For several x64 versions, up to 5.4.1.2 (which I'm currently using), Writer and
Calc have destroyed my work on several occasion by suddenly saying "general
input/output error" to all tries to save the file currently open. When this
happens, I can only close the program (losing all changes made till my last
backup). The file I tried to save to is truncated to zero bytes, though I can't
say whether it was truncated by the save that caused the aforementioned error,
or the one before that. 

The error appears without rhyme or reason, but always on file save, and seems
to occur quicker and/or more often when I save more often (which I did to lose
less work in between saves, to no avail). 

The problem has occured on two different Win10 professional installations on
two different computers, with files of vastly different sizes, but always
created with one of those LO installations. I have tried several LO versions,
but the problem persists. 

If this happens, nothing can be saved (even after restarting LO or the whole
machine) until I delete the user profile for LO. After that, I can use the
suite again for a few minutes to a few days until the problem reappears. The
files however, are gone. All I can do is get the backups and redo the changes.

I'm usually saving the files in question to a newwork drive (SMB share or SFTP
drive using ExpandDrive or MountainDuck), but once the error occurs, the file
can't be saved to any drive, be it remote or local. 

This seems to be related to a number of bugs reports of both LO and OO going
back up to seven(!) years, e.g.

I have stopped using LO for now as I can't afford to lose any more time or
files with this.
