40tb pacs storage seems empty but we knew there is 17 tb data is there any possible reason to show disk as it has been formatted. when I used data scavenger I found all data . ?t was 12* 4 tb raid 5 storage in 1 volume. ?t was our PACS storage with win 2008 server. Our files on that storage was reachable till ten days ago but now the volume is empty. I have a suspicion about someone changed the volume information. Because data scavenger can find and restore image files and I can export them. So I am asking, is there any possible way to show a volume empty without wiping it. So I am asking how can I restore system files to rescue our hospital pacs files. Maybe someone deleted system files NOT accidently. And is there any app to restore only system files.....
