From Linux OS using Dolphin I moved ~5MB document fi= les from Win7 partition to Linux /home/xxx/Documents directory and rebooted sys= tem to return to Win7. Made changes in Win7 as needed and booted back into Lin= ux.=20 I noticed the entire Documents directory was missing, about 50GiB files.=20 Immediately shut down system and booted up Linux on duplicate drive contain= ing image from about two weeks prior. Made read only image of /home directory = from corrupted drive and placed on external 1 GiB backup drive. Using R-Linux, extundelete, debugfs no trace of the Documents directory can= be located on the image or the original /home directory. I can see files I intentionally deleted during normal operations for over a week prior. fsck, smartctl indicate no disk issues. I have not tried to reproduce this issue. This event seems very similar to the one discuss in this link but I have not been able to locate that particular bug. https://www.itnews.com.au/news/stable-linux-kernels-hit-by-serious-file-sys= tem-bug-320709 I entered bug report on the bugs.kde.org bug tracker(432762) but was told t= hat the issue is lower level than the Dolphin gui which I was using. Apologies if this is a duplicate, but I could not find a similar issue on t= his tracker. --=20 You may reply to this email to add a comment.
