So I have x2 HDD's in a Raid config in a netgear storage box. I have created a iscsi connection between that data to show up as a volume with mapping of B: (backups) and it is 2.7TB in size. I have been pointing my backups to that target for almost a year. Backups are failing and I noticed that the reason is because there is not enough space. The drive is now empty but says there are 800gb used but I cannot find it! Anybody have ideas on this or used a similar method?
