Data Recovery from an Internal 2.5 inch HDD with Dynamic and Invalid disk status in Disk Management

[NInja92]

 have been using an HP notebook 15DA0077tx notebook (which has 8GB RAM, Intel Core i5-8250 Chip, INTEL UHD Graphics 620, NVIDIA GeForce MX10), for the last 2.5 years on a1TB Hard disk running on a Windows 10 v1908 OS. However, for the last few months, the system performance had been degrading as it was very slow and took up minutes to start any applications. Even the Windows booting took 2-3 minutes. After running routine BIOS Diagnostics; it reported the Long DST test FAILED, which meant I had to eventually someday replace the HDD and backup the data on my HDD. Before I could do that the HDD simply didn't boot all of a sudden one day and I had to replace the older HD with a new SATA 2TB HDD. I have installed the  Windows 10 v1909 OS on the 2TB HDD. However, on trying to recover data from the older 1TB, it's not displaying in win explorer. On checking Device management, the Disk Status is displayed Dynamic and Invalid while the Device Manager displays it as a USB Mass Storage Device (Refer Screenshots):

So what should I do next so that I would recover all the data (around 800 GB) without any loss and display all the drives on the hard disk with proper file structure? I checked out the following procedure on the Microsoft Disk Management troubleshooting page:

Win Disk Management Troubleshooting

But I doubt it will result in loss of data. I need my valuable data by any means. Suggest any means possible. Will I be able to use the older HDD as a backup drive by somehow getting rid of the bad sectors which may have appeared?

Dynamic disk happens when you force the creation of too many partitions on a drive.

All you will be able to recover at best from the drive is personal data. You will not be able to recover settings, website information (including user accounts and passwords) or applications.

You will also need another drive large enough to hold the files and folders you want to recover because you can't recover them to the old drive.

Your best bet for recovering data now is to do the following:
1) Download and install this utility on a working PC http://www.majorgeeks.com/news/story/recover_data_in_3_steps_with_minitool_power_data_recovery_free_...
2) Connect the old drive, the one with the files and folders you want to recover, to the working PC
3) Connect something to that PC to hold the recovered files
4) Run the data recovery utility to see what can be retrieved from the old drive.

If that tool does not find what you need, an alternative is Recuva http://www.piriform.com/recuva

And, if that does not work well, the best tool out there is this one, but only the demo version is free https://www.runtime.org/data-recovery-software.htm

Thanks for replying. The first link you shared, major geeks, the file in it doesn't exist. The second one I don't know it seems it being a demo version it wouldn't allow to recover large amount of data, mine being around 800GB.

Please let me know in your knowledge, whether the disk needs to be made Basic in Disk management before data recovery or not using you recommended software. Will that result in any data loss?

Thanks for the heads-up on the links -- I don't use these so I don't know when they expire.

Here is a working link for the first one:  https://www.minitool.com/data-recovery-software/free-for-windows.html

As to the second, it looks like they have a Pro version now, so the free version is likely limited.

The all round best is that last one, but you have to pay for that.

The data recovery apps do not actually read the file system, unlike Windows, so as far as I know, they will work even if the disk becomes unformatted.

None of the softwares worked. Only one of the drives which had the OS installed in it worked. But others didn't. If you can recommend anything else please do. I have not tried Recuva because could not find the PRO version for it.
