After several days since I reported this issue of data loss from filesystem corruption - it has now miraculously recovered !
I'm not sure if it did this on its own, or from intervention of my own actions. I kept tending to a possible recovery on a day-to-day basis. The actions I took were to keep checking the Properties of the corrupted disk showing the number of bytes - which corresponded to a complete set of data - yet I was missing several gigabytes of directories and files. I thought it could be an erroneous attribute where the files were somehow hidden on the disk. In which case, I made sure to unhide any files (e.g., 'Show Hidden Files' in the menu selection). This had no immediate response as one might think. (Why would standard data files all of sudden become hidden or unhidden ?). But then the system was rebooted a few times as I also checked for any signs of recovery through the Windows Operating System. I run Windows on a separate SSD drive and this is where the corrupted directories were completely inaccessible. However, between reboots Windows performed diskchecking - although this is considered some old routine Windows always wants to perform. I also opened up Windows Disk Management, and puttered around a bit, but didn't really perform any actions since there was really nothing I could do, and it claimed the filesystem was healthy (although I could not access it). A few more reboots between operating systems and I decided to quit, but I left the PC on overnight with an open internet connection. Another day passed. The next day, I decided to take one more stab at locating the possibly hidden files with some additional insight. But when I went to open up the disk in Ubuntu, the directories and files were all there - as if nothing ever happened. I rebooted to Windows and everything was also accessible from Windows (as it should be). Somehow, between Linux and Windows the corrupted filesystem fixed itself - yet this corrupted state carried on for several days. I can finally breathe a sigh of relief (since I recovered my data), but I think I'll try a whole different installation of Linux. That last installation (Ubuntu 24.04 LTS) was no fun at all. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2078283 Title: File system corrupt in Ubuntu 24.04 LTS (bad version ?)
