I lost 2-3 hdd's due to old age and lost all data on them. Some other 2-3 hdd's make a lot of noise while in operation and probably failing. I use VVV to catalog the stuff and to see which files have 2-3 copies, i need to manually search each file name. It's really tedious. I was wondering if there is another program that does this automatically. I let it scan the hdd's and it makes catalogs of each hdd and tells me which files don't have duplicates when i press a button. I have like 18 hdds ranging from 500GB to 4TB full of data so manually searching is too much work now.
