I am in a serious problem here.
I am running dual boot windows 10 and Ubuntu. The last time I accessed Windows was 3 weeks ago and I'm fairly sure that it wasn't in the middle of updates or anything when I started Ubuntu again. Furthermore, I do not use hibernate at all.
I have a shared drive between my Windows 10 and ubuntu. I logged in to Windows this morning and tried to access the shared drive. When I tried to access new folders in the drive that did not exist before when I was logged in to Windows, Windows complained something about the files being corrupt and I noticed that those new files disappeared.
What's worse is when I logged back in to Ubuntu, all those new files were gone.
If it helps my case, I would like to add that the last time I accessed Windows, when I logged back in to Ubuntu, Ubuntu complained that it couldn't mount the shared drive and so I followed some instructions that you had to type on the terminal (sorry I don't remember it at all).
I have 2 important questions now:
1) How can I prevent this from happening in the future?
2) How can I recover those files that I lost?
I sincerely appreciate help here. Those files are important for my research.
Thanks and I hope to hear your suggestions soon.
Thanks for the responses I've been getting! I have tried photorec and I'm now sorting through my files. If it fails, I'll try rkeating's suggestion below.
I will now back-up my files but I fear that that will still not solve the problem even after disabling all the windows updates, etc. If I did not access the shared drive from windows, nothing would have happened. It was when I clicked on a relatively recent folder that things went wrong. After doing so, my old files were still accessible from my shared drive. How do I ensure that I will be able to access files on the shared drive from Windows without any problems in the future? I appreciate your suggestions a lot! Thanks!
