Hi, sorry for the looooong delay...
I did all the backups, both an image and files, just in case, with no errors. On these past days, the reallocated sectors count increased to 56 after doing the short and long self tests, but they both completed without error, and it has not increased since then. Windows has not marked any bad clusters if I run CHKDSK.
I already had CrystalDiskInfo and Seagate Seatools. I think the former gives the same information as GSmartControl and the later allows triggering the Seagate drives self tests too. I like CrystalDiskInfo because it shows the hex value of the "raw value" field, allowing to disect the value from some fields that seem to contain more than one value (i.e. seek error rate, temperatures...). This is the last SMART information:

After doing the self tests that reallocated a few more sectors, the drive doesn't feel as slow as the day I couldn't run DISM, so it may have reallocated the sectors that were causing the trouble back then... Anyway, it seems the disk is slowly starting to fail and even if I can get a few weeks/months from it (I already have backups), it will eventually fail, isn't it?
I suppose there is no point on repairing any more corrupted files until the disk is replaced, isn't it?
On top of all that, I'll be moving to a new home, so I may not have Internet for a few days...
Thank you very much for all your help so far
