Hello again!
I told you that you'd miss me when I'm gone. :-]
Please, I need recommendations or strategies for recovering data. I had a flash drive become unreadable, after I plugged it into my new printer to print out some documents that had been long in waiting. Then, before I could save myself, I had a 1.5 TB hard drive also fail. On this hard drive is (of course) the source of those backup copies on the flash drive. This is the partition which I was just about to backup.
I have several hard drives, from 200 GB up to 8 TB, from 20 years old to brand-new; all are WD, except for one which is Seagate. Guess which one failed? I forget when I got it, or why I ever would have got anything but WD, or why I would have put anything important there.
I have used ddrescue to try to recover the data, as well as other forensics tools. Recovered images (img and iso) are saved, and taking up space, but I cannot determine if there is any useful content in what was recovered. The failing partition has not been deleted. It cannot be read or mounted, so I have just left it like that, so that I can try to save it.
Every attempt to recover the data gives the same result: 2 errors, 3072 B, that cannot be read. I tried using tools to look inside the saved iso image, but no luck there. I don't want to erase or format the failing disk partition until I am sure that I have recovered the data.
My last hope is that I have another 1.5 TB hard drive; I could try to write the disk images to that partition before I format the old drive. But first, of course, I would need to backup materials from that drive, and now I am running out of space again.
Bill
P.S. And if things were not bad enough, the skies here in San Francisco are a muddy mixture of orange, black, brown and gray. At noon today, it looked like the middle of the night.

you can try "testdisk" on the image - or better on a copy of the image.

Thanks, Nik. I am surprised that I didn't already have that package.

Can you not just mount the ISO?* Then you'd be able to see what was able to be saved with standard tools. Or even get jiggy and open up a hex editor is you're so inclined...
Best, Michael

No, so far nothing seems to make a difference, and I cannot even get much information from it. When I ran ddrescue, everything hummed along smoothly, no bad sectors, right up until 99.9% complete (literally!), then there were 2 errors, 3072 B (total, I believe), and these bits could not be read even when I let it run for 500+ passes.
Running testdisk now, on both iso and img files -- different copies of the same source. I am getting a message now, the run is about half-finished:
check_FAT: Unusual number of reserved sectors 4 (FAT), should be 1. check_FAT: Unusual media descriptor (0xf8!=0xf0) Warning: number of heads/cylinder mismatches 64 (FAT) != 255 (HD) Warning: number of sectors per track mismatches 32 (FAT) != 63 (HD) FAT12 54360 71 48 54361 11 50 12288 [Firmware]
The message is the same on both. However, it ought to be ext3, not fat-anything; unless these sectors are in reserved system space or something, this seems to be wrong.
I don't even use this drive in connection with any fat filesystem; only my flash drive (the one I mentioned, which also failed) uses fat-32. I have one ntfs drive; the rest are all either ext4 or ext3.

There's another option but a wee bit expensive.
Purchase the same model SG drive (or whatever model etc) that failed and swap out the electronics.
Assuming there's no mechanical damage, it will work. It's often why I buy drives in pairs.
Hope this was helpful.

It is an internal hard drive, not external. Is that what you mean?
