Small up.
Defrag is extremely slow. Defrag was started about 30h ago. Now it's estimate completion in 12 Hours but this time increase by 30 minutes every hour...
If I compute my own estimated completion (based on two screenshots spaced 15 hours apart) i found : 1306 hours left (54 days)... ( It's a 540GB NTFS partition)
Yesterday I compute 48 days left...
