Hello dear community.
I was shooting in Japan and had all my Data on a external HFS+ WD 2TB which I bought there. I KNOW…

I normally ALWAYS back up two/three times at least until the Project is done but I only had this 2TB with me and since it was just for myself without a client I trusted the fresh HDD. The Footage converted on my old mac for like a week and I got about 100+ GB of ProRes files out of the MLV's.
Then I had some other Files copied out of the HDD and the copy task failed. The HDD didn't react on anything and, of course, I tried to repair the drive with Disk Utility but it didn't work. Disk Warrior couldn't help too, but OSX somehow connected to the drive in a special mode (I forgot the term) and the files are accessible, but VERY VERY slow 10-50 kb/s! Even just to show files in folders is very slow. So it is theoretically possible to get the files, but it would take about a year to do so.
My Idea was now to somehow extract the previews of the files, or all the beginning frames "*_000000.dng" of the 300 MLV's to see which clips are the most important and just leave the mac on for a couple of months to get at least something out for my demo-reel with which I intend to apply to Film-Univercity in May. MLVFS indexes the MLV Folder but as soon I want to search for frames containing the name "000000" it shows maximum one file, then MLVFS crashes and throws the virtual volume off.
Might there be a way with the ProRes Files? They don't need MLVFS but Finder or Bridge alone don't give me any Thumbnails. I searched the net for solutions but there was nothing possible. Giving it to a Data Rescue Firm is not in my budget too. Does somebody have a Idea what I should do (besides Back up more often in the future)

to get out the Thumbnails or even repair the disk?
I'd appreciate any help!
