What tool are you using for imaging?
Have you tried to read from different areas?
Have you tried to image head-by-head?

Have you tried backward copy for instance?

Attach the log from hddsuperclone. I can analyze it and perhaps give some insight on what is happening. I prefer a log that was started from scratch with hddsuperclone, as importing a ddrescue log can make it much more difficult to analyze.

Just curious : what did you use to input those commands (1st post), if you don't have a professional toolset like PC3000 / MRT ? (I guess you don't if you're using ddrescue / HDDSuperClone, which might be the best free tools and possibly the best software-only tools available, but still a far cry from what professional hardware + software solutions regularly mentioned here can accomplish, from what I could gather.) I'd like to learn that kind of trick on-the-cheap...

Regarding your above reply : you can still copy backward and target a specific area at the begining of the HDD. With ddrescue, use the -i switch. If the volume is in NTFS, with ddrutility there's a tool called ddru_ntfsbitmap, which can create a mapfile based on the $Bitmap file, and restrict the copy to the areas marked as allocated (very useful when cloning a failing HDD with a lot of free space).
I haven't much experience with HSC, but you're lucky enough to have the author providing you with personal guidance here ! :)

If the rescue is started with hddsuperclone with the default settings, after it is a bit into phase 1 I am able to diagnose some things from the log. Such things as if it is suffering from some sort of slow responding issue, or has a bad head. I do not yet have any documentation available for how to do that, so I am always willing to help with the diagnosis.

Someone just posted in the discussion area of ddrutility with a possible method of targeting ntfs files, using the tools available in ddrutility along with spreadsheet software. It is somewhat complicated and requires multiple steps, and I am not sure the average user could do it, but the concept seems solid. It is a very clever idea, and I am quite impressed with it. If he is successful with the recovery, I may have to post that how-to in some other places.

Well, that's kind of you anyway – but I suppose that it also helps you to improve your programs, by trying to figure out unexpected issues and implement specific workarounds. I mentioned HDDSuperTool in this thread, asking if it could do anything useful in the case I described – what would you have to say about it ? I tried HDDSuperClone for the first time with that ST3000DM001, but at that point it didn't seem to fare any better than ddrescue ; it's possible that I couldn't figure out how to set it properly to get the best possible result. But it seems unlikely that I can salvage significantly more than I already did, i.e. recover at least one of those 6 corrupted video files in its entirety. At least I was hoping that I could learn something from this unfortunate experience (which could have been way worse), but the replies I got have been quite frustrating...

What discussion are you refering to ? I'm not sure if I understand what you mean by “targeting NTFS files” – aren't those tools already aimed at targeting NTFS files ? (Bitmap and MFT, respectively, for ddru_ntfsbitmap and ddru_ntfsfindbad.)

HDDSuperTool will not help you in either case. There are no scripts in it for Seagate drives. The only firmware access I am aware of is with terminal, and I am no help there.

I can only provide a possible diagnosis with HDDSuperClone by analyzing the progress (project) log file as the rescue attempt progresses, sometimes very early into the attempt. Sometimes I can even tell some information from a screen shot. But I am no help if that information is not provided. Your statement that hddsuperclone seems no better than ddrescue does not provide much information, although it is not a good sign for the health of the drive.

Ddrutility home is on Sourceforge, the discussion is there. Someone has potentially figured out how to use the ntfs tools of ddrutility to target selected user files, not just the Bitmap and MFT.
