I need to delete around 1TB of data off of one of our ReadyNAS 2100s. Deleting all this data manually is a no go so is there any free software or scripts I can use to get rid of the data? I tried using Robocopy to delete the data but it kept throwing up (lack of) permission errors despite the account having full access to both folders and all data inside.
Any advice is much appreciated. Cheers!
