I should have known better..and I think my data is well & truly gone but if anyone can help...!
I was doing my regular R&R backup to my Lacie ext Hd when I noticed that memory space had mysteriously disappeared. I found that R&R was not-overwriting previous backup files...so after unsuccessfully trying to delete individual files I went to 'Create Recovery Media'....(I know what you're thinking! First mistake, right?).
Find my HD and unchecked 'Do not destroy exisitng data' (BIG mistake!). I thought it only refered to existing BACKUPS!
Result: it renamed my extHD and wiped everything! DOH!
Is there any way back?
Help me, OBI-ONE-KENOBEE..
