Read data on SD card which was formated as Internal storage of Android OS I have got Lenovo Vibe K5 Plus with Android OS 8.1.0, I pluged in new SD card (Kingston micro SDHC 32 GB) and this SD card was formated as Internal storage, so data on this SD card was accessable with connecting mobile phone to PC, but yesterday I removed SD card from mobile phone and I did a big mistake that I clicked something in Settings -&gt; Storage, something like forget SD card. So now I have got SD card with my data (photos, music, etc.) which I can not read in PC with SD card reader...is there any chance to read my data from this SD card? I looked that in my phone is some data .nomedia
Thank you for you help
The &quot;forget&quot; option tells the Android system you no longer have the card. What it then &quot;forgets&quot; is the encryption key needed to encrypt/decrypt this specific card. So basically you've locked the safe and threw away the keys; without the keys, there's no reasonable way to open the safe again.
Thus, your data are lost. It might be possible to regain the key (e.g. if the device is rooted; you could create an image of all its file systems and use forensic methods to find and extract the deleted key). But not only would that require your device to be rooted, the effort to find and extract the key is not low, and chances are it's meanwhile overwritten. If your data are worth a 4-digit value (EUR or USD) to you, you could contact a forensics company to give it a try – but chances are rather low.
Permit me a note to one of your comments on your question:

I do not have any backups, because all worked properly.

That's exactly the point-in-time when one does perform a backup: you need the data intact. You cannot create good backups of a broken system – but at that point you'll need a backup to repair it, as we've just learned.
