I got a wd my studio FireWire (1tb) that did work well wirh an imac (wirh yosemite, and raid 1)
I connected it wirh a new mac (by a thunderbolt adapter if it matters) and Finder says that there are 0 files and 999gb available on the disk.
If i plug it again on the old Mac, it works the same way (no files on it). Yesterday it worked well.
Actually, finder’s informations say that there are 999gb on the disk but also 650gb used. Maybe my files are somewhere, but how can i access?
Being a raid configuration mode disk, i got no copy of those files. Argh.
