The way file/folder names work on Windows is discussed over on Microsoft's website. However, that provides only a glimpse of the overall truth.
NB: I will not discuss the aspect of codepage issues which can arise from the way a "foreign" system accesses an NTFS volume. I think this is sufficiently covered in comments and the other answer. I will ...
I am posting this answer just to say how the problem was solved, thus summing up the comments made to the original question, which might be useful to others.
I have fixed the problem in Linux, where those folders had been created, simply by shortening the title of two or three of the video files, which had long names but no obviously odd characters like ...
If you read down that list, see how many have been tested to work on macOS… I can't find any.
It's generally accepted that you can't get SMART data over USB on Macs, because they don't provide SCSI passthrough.
There are some exceptions requiring an extra plugin available from the makers of DriveDx, who note…
If you want to perform external drive ...
The disk seems to have died out because of the sudden power cut, or perhaps the power
cut was preceded by a power surge that fried some weak component inside the disk.
This is not a normal behavior for a hard disk, that is supposed to be more resilient
to power cuts or small surges.
I would suggest to return the disk as being defective (no need to mention ...
Yes, there is a chance that your data is corrupted, but it is small. Chkdsk checks the filesystem (is file names, indexes, file tree) and fixes it if need be. It does not check the contents of the files.
The Seagate tools do not know anything about the files or filesystem - they are looking at the disk level and are reporting everything is OK.
It is unlikely ...
The CHKDSK test tells you that, as of the time you ran it, your hard drive is OK (or not, if that is the case).
Further then, since you had a good test, it is fine to keep using it.
However, in the crash, the operating system and/or browser may easily have hiccuped and therefore there is no guarantee that data being downloaded and/or saved was not corrupted.
It is possible to swap the board from one drive to another, provided they are the same/compatible PCB boards. You may have to swap a BIOS chip which would contain information specific to your drive.
If the problem is with the drive mechanism, you won't have success just swapping the board however.
Depending on your proficiency with electronics and soldering, ...
The reason for power outage could be several:
Power outage from the power line
Power outage because there is a lightning strike.
If you are getting a power outage because of lightning strikes that could be fatal for your electronics.
If that's the cause, there is little almost nothing you can do. If the inside data ...
dd-rescue IS working here.
The OS detected an error and removed the disk so ddrescue could not continue operating. You should unplug the disk, plug it back in again - check that it is still /dev/sdb (or adjust your command accordingly) and rerun the command - because it writes a logfile it should continue where it left off. You may need to do this ...
Even though this discussion is quite old, I found some facts not being exposed for a new visitor. You need to consider several other things before deciding to go with 1 big partition per drive such as :
Scan time for viruses or disk errors
How much disk space is wasted for holding partition data
Index sizes and indexing time.
I have come across ...
