I corrupted my data by taking out the SD card (which was used as internal storage) multiple times without running:
Since using the SD card as internal storage was encrypted the card to be used only inside the same device (Nokia 6.1+) and the card's data wasn't accessible neither in another device nor inside an SD card reader.
So, I reinserted this 1st SD card back in the device on which it was used as internal storage.
Then, in order to back up the data (which was not readable even in same device).
Copied the data (around 30GB mainly media files) from adopted shared internal storage to my PC via MTP using a USB cable.
Data was not readable in the PC as well.
Now, I don't know whether the data that I copied to and is present in PC is simply just corrupt or corrupt and encrypted.
I don't have the 1st SD card anymore.
All I have is the corrupt/damaged data stored on my PC.
Can anyone help me out here first to know whether the copied data on my PC is simply just corrupt or it's encrypted as well along with being corrupt?
Tried various recovery and repair methods for months but couldn't repair the corrupt data.
Back to the present: Today, I tried to repair the corrupt data (Mainly images) using online tools but couldn't.
The online tools required some normal images from the same device as reference files.
So, again used a new SD card as internal storage just so I could use the normal images from the internal shared storage as reference images.
After successful using this new card now even these new (unimportant) images are not opening in the same device.
Thumbnails of around 30% of images are visible in the Google Photos but not all images are opening out of these 30% and the rest are neither showing thumbnails nor opening.
On opening from the file manager (default as well as 3rd party) not even image thumbnails are visible for any of the images.
On opening individual images on the file manager, it displays the error: “Could not open file.”
How can I repair the data (images and videos) presently inside my PC which got corrupted after 1st use of 1st SD card as internal storage?
