Edit: My DS1512+ with 5 drives is basically silent. A Drobo is far noisier.

I ran into this same issue with a ReadyNAS. I deleted the share not knowing it would remove the files within the share. I was thinking it would handle it like a Windows share... anyway the storage space didn't free up (might have eventually... who knows) but I couldn't access the files. Checking later I found out that's the expected behavior and luckily like you I had a backup...
