Raid 1 recovery using Puppy Linux

Hi
I have a Buffalo Link Station Duo using Raid 1 with 2 x 2TB drives. The unit now fails to launch and having withdrawn the drives and connected them directly, I can hear one clicks and fails to start. I am now down to one of the drives, connected to my windows computer, booted up with Puppy Linux and can see the drive - sdb1, ext3 but no files or folders I recognise except these 7 :
lost+found
Build date.txt
conf_savet.gz
initrd.buffalo
log.tgz
ulmage.buffalo
ulmage.buffalo.org

Can anyone help a linux novice find my files please?

If it’s RAID 1, the drives are supposed to be mirrored, are you saying both disks corrupt ?
