Windows 7: External HD NTFS -> Raw Mmmmmm

Going back to your post #1, Windows was reporting "Data error ( cyclic redundancy check)". When you tried to run checkdisk, it refused saying it can't run on a RAW drive. This problem sorted out by itself ( I still don't know how) and you were able to run check disk and it ran to completion.Partition Wizard shows that the GPT structure is fine and so it is not a partition related problem.Now Lucid Puppy also says error for Source file Input/output error.

As one who has been dealing with data recovery ( though not a data recovery professional ) I can only visualise it as due to bad sectors. But in this case it appears that I may be wrong. The problem of your inability to access the lower tier folders can be due to the way you had created the folder structure and named those or some corruption that had taken place in the folder structure. I may not be able to deal with such a problem.

To clear that bad sectors are not the cause , you may run SeaTools for Windows and check the health of your drive.If it does not report any problems with Quick Test and Extended test - which of course will take a long time - then it squarely revolves around the folder structure/ corruption and I shall pass it on to other experts to deal with it.

Let us wait and see what other experts have to say.

A few things I don't understand is how it became NTFS when it was GPT? The folders and data can't always be access as well when going below the third tier folder structure.

Amazon Cloud Drive and Pictures Waiting To Be Sorted.

ACD --> Videos --> Anime, TV Series, Cartoons, etc.
Pictures Waiting to Sorted --> Pictures and a ton of them no folder at all.

I done a scan with SeaGate already and it labels it as nothing wrong with it. With the external HD plug in it takes over a 2 to 3 minutes before my system boots up and sees the external HD. Just some follow up information.

MBR and GPT only define the partition structure. The file system in both cases will normally be NTFS.

Since bad sectors have already been ruled out, it shall be for other experts to chip in and sort out of the problem.

So keep watching.

On my part, I would suggest the following:

Download install and run GetDataBack Simple Data Recovery https://www.runtime.org/data-recovery-software.htm ( Also read all documentation on that page.) The initial scan will be done at Level 1. Check whether it shows all your folder structure and files in it. You can also preview the files and check all your files are OK. If Level 1 does not show anything, you can try Level 2, Level 3 and Level 4 in that order.).If it shows all your folders and files, you preview those and satisfy your self that everything is fine, you have to buy a license (USD 79) to copy those to another drive.

In case you do not want to buy , and you will be happy if you can recover the files without the folder structure and original file names you can try PhotoRec which is free. Guide to using PhotoRec recovery software.
(Straight away go to the topic Recovery in it.)

Keep these two options open in case other experts also can't help resolve the issue.
