I'm trying to add some photos to my SD card, which I had previously formatted and turned into internal shared storage using my phone.

But everytime I double click on the SD card after inserting it into my computer, I get the following error:

You need to format the disk in drive H before you can use it.

I can only open it on my computer if I wipe it and change it to a portable SD card. Even when I open the contents of the card while my android phone is on and hooked to the PC, there are some files that I cannot access because they are "currently in use" while the phone is on.

How can I open the files in the SD card on my PC without having to change it back to a portable SD card? (I need it to remain an internal storage because my phone's actual internal storage is filled up.)

I am a beginner who is not familiar with how to root my device so if there's a way I could open the contents of the card using a software or program instead, I would appreciate it.

    That's how Adoptable Storage is supposed to work. You can't read the adopted card on PC: “When external storage media is adopted, it’s formatted and encrypted to only work with a single Android device at a time. Because the media is strongly tied to the Android device that adopted it, it can safely store both apps and private data for all users.” – Irfan Latif Oct 8 at 22:51
  • I see. But even if I unlock the phone (decrypt the SD card) and hook it up to my PC, I still can't move files around the SD card because they are in use when the phone is on. Is there a work-around for this? – brainkid Oct 9 at 1:07
  • How exactly did you decrypt the SD card? How exactly do you know that the files are in use? – Irfan Latif Oct 9 at 1:31
  • I decrypt it by unlocking my phone when it's connected to the PC. The PC tells me that the files are in use when I try to delete or move them. – brainkid Oct 9 at 2:41
  • Screen unlock has nothing to do with SD card encryption. It's not decrypted unless you reformat it as Portable Storage. So when you connect over MTP, PC says files are in use. Where are those files located? I mean which directory/path? – Irfan Latif Oct 9 at 2:45
