Description:
Writer .odt file becomes randomly blank and zero bytes in a BitLocker encrypted external SSD in macOS 10.14 Mojave

Steps to Reproduce:
1. Attach BitLocker encrypted Samsung T5 external SSD to MacBook Pro (2017)
2. Mount SSD with M3 BitLocker app (https://www.m3datarecovery.com/mac-bitlocker/) or BitLocker Anywhere for Mac (https://www.easyuefi.com/bitlocker-for-mac/bitlocker-for-mac.html)
3. Open Writer, create a small new .odt file. Open and save several times, make small changes here and there, exit Writer and save on exit. Do this several times and confirm random disappearance of the information contained on the file.
---

Actual Results:
.odt file became completely blank and all information on the file is lost. The information appears to be lost in conjunction with recent activities of saving or opening of the file. That is, soon after opening or closing/saving of the file.

Expected Results:
Save the changes and maintain integrity of the file. In the same exact environment and circumstances Microsoft Word does not display any errors or information lost.


Reproducible: Sometimes


User Profile Reset: No

SSD is formatted NTFS.
Comment 2 Alex Thurgood 2019-04-12 06:53:34 UTC
Given the very specific circumstances, it is unlikely that anyone from QA will be able to confirm this.

How is the external SSD connected to the macOS system ?

Currently, there is no way to tell whether this :

- is a macOS problem ;
- is a BitLocker problem ;
- this is a LO problem.

LO is not optimized for macOS. There's no way of telling whether LO's internal file representation memory management is compatible with the way BitLocker is designed to function on macOS.

There have been reports in the past of similar problems affecting USB-connected drives (irrespective of whether or not they are encrypted). Perhaps the behaviour you are experiencing is comparable.
Comment 3 Alex Thurgood 2019-04-12 07:09:49 UTC
Does the problem also occur with a FAT/VFAT formatted file system on the SSD ?
Comment 4 alegoje 2019-04-12 21:12:59 UTC
SSD is connected through USB cable to Dell D6000 docking station.
I have not attempted to reproduce the bug in a differently formatted SSD.
If possible, I will test this when time permits. Thank you for looking into this potential bug.

Hello Alegoje, a new major release of LibreOffice is available since this bug was reported. Could you please try to reproduce it with the latest version of LibreOffice from https://www.libreoffice.org/download/libreoffice-fresh/ ?I have set the bug's status to 'NEEDINFO'. Please change it back to 'UNCONFIRMED' if the bug is still present in the latest version.

Please also try to answer the question from comment 3.
