Hello, sorry for the long delay.
I did apply the last fix (it was applied successfully), but I couldn't run DISM:
It seems there is some problem with the hard disk. Before starting this thread, I did both short and long tests with Seagate Seatools, and looked at the SMART information with CrystalDiskInfo, and it came out clean, but when I did try to run DISM for this last reply, it was not starting... I waited for 20 minutes and the percentage progress bar did not even start... Using CrystalDiskInfo, I have seen that now it has 40 reallocated sectors (there were none before). There are no pending sectors, nor uncorrectable sectors, but suddenly there are 40 reallocated sectors.
Can this be the source of the corrupted files? The disk should not silently corrupt data, isn't it?
I think I'll be doing a backup (work files to a USB drive and a full disk image using Macrium Reflect), and look at the CrystalDiskInfo SMART data for a few days to decide if the disk should be replaced... If no more reallocated sectors (or pending, or uncorrectable) appear, then maybe we can resume the corrupted files replacing process.
Do you think it's ok? Should I do something else?
Thank you
