Hello all, I need some advise with regard to rescuing data from a raid disk. History: I gave a friend a Synology two bay NAS set up as a raid array to store their data safely and suggested that it was backed up regularly to another disk as well for safely. All their family photos for the last 10 years or so are stored there - the only copies. Husband (Windows User) familiarized himself with the Synology and things seemed to be OK. However he decided that I was being overcautious and that extra backup wasn't needed. :-( Unfortunately one of the disks failed and husband in his wisdom decided to 'fix' it and instead wiped all the data from the good disk - disaster. Current: I can access the damaged disk by attaching it to my Kubuntu workstation, reading it with testdisk and all the partitions and data appears to be still there, but I can't see the files because of the RAID filing system. I have tried ddrescue which I have been able to use to copy data from the main partition on the damaged disk onto an old ntfs disk I had lying around but it is still unreadable as the raid filesystem refuses to mount and I still can't see the files. I have the good disk still (no data as it was wiped, but partitions still there) and another spare identical 2 Tb disk as well. All I want is to rescue the photo files from the disk - I can then replace the disks in the Synology NAS and reinstall as well as having the photos safely saved elsewhere. How am i best to proceed?
