Additionally, Decryption of any SD card will require that card to be inserted into the original device that encrypted that card. 'This SD Card cannot be decrypted because it was encrypted on another device.' Okay, so I read both the links you shared. The former one sounds logical tho its old and you're probably right about the advanced encryption techniques which is why i'll make a copy of the sd card first. Not trying the latter one because it needs root. Hi, Once a Micro SD card is encrypted it must be decrypted by the same device before using it with another device. When it is not the saved data on the card will be lost. That is how this security.

'How to recover lost data when PC can't read SD card?'

Step 1. Recover Data from A Micro SD Card That Cannot Be Read

Today, with the rapidly developing data recovery technology, recovering SD card data is easy. Many data recovery programs are now made available in the market to easily and effectively recover lost data. For instance, both MiniTool Power Data Recovery and MiniTool Photo Recovery can help to effectively recover SD card data without affecting the original data because of their excellent performance, high security and simple operations. Here, in my case, I prefer MiniTool Photo Recovery since I only stored photos and videos on my SD card. The steps are shown below:

Attention: Before recovering data from SD card that cannot be read by PC, we should download MiniTool Photo Recovery from its official website, and then install it on computer according to prompts. After that, connect the SD card to PC via card reader.

A step-by-step guide to recovering data when PC can't read SD card

Launch MiniTool Photo Recovery, and then click Start button to start SD card photos and videos recovery.

From the main interface, we can find that MiniTool Photo Recovery not only can recover data from SD card but also supports USB drive/computer hard drive data recovery. More importantly, camera users can directly connect their digital camera to computer and then run this software to recover lost data. For more information, please refer to How to Recover Photos from Digital Camera Memory Card.

Next, select the SD card that cannot be read by PC and then click on Scan button located at the lower right corner to begin scanning on the device.

In this window, you can click on Setting feature to specify needed file types before clicking on Scan button. For instance, if you only want to recover JPEG photos, you can only check JPEG Camera File (*.jpg) and JPEG Graphics file (*.jpg), and then please click on OK button to confirm this setting, as shown below.

After scanning, you will see this scan results in a tree view as shown below, and the types of recovered files are displayed in the left list. Now, you can preview picture by double-clicking on it, select all the pictures you need as well as other SD card data, and click on Save button to store them. It is recommended to store selected files on another drive! Otherwise, the lost/deleted data could be overwritten!

If you decide to get an advanced edition, you don't need to close MiniTool Photo Recovery. After that, you can easily click on Register Now button after receiving the license key MiniTool sent to you via email, copy and paste the license key to register, and continue to save selected files.

After getting lost data back, it is time to fix SD card not reading in Windows 10 issue.

Step 2: Fix SD Card Can't Be Read by PC

Method 1. Format SD card

Open Windows Explorer, right-click the SD card, and then choose ' Format…' button.

Now, specify file system, volume label and check Quick Format, and then click on Start button.

After that, you will receive an error message that reads: 'WARNING: Formatting will erase ALL data on this disk. To format the disk, click OK. To quit, click CANCEL.' Here, as we have recovered lost data from this SD card, we just need to click on OK button to continue.

Finally, you can click on OK button when you get a message saying: 'Format Complete.' Thus, all work has been done.

If this method doesn't work, you can try running CHKDSK to scan for errors!

Method 2. Run CHKDSK to repair corrupted or unreadable micro SD card
Press Windows+X to open the Power User menu, and then click on 'Command Prompt (Admin).'
In the new Command Prompt window, type chkdsk E: /f /r /x. Here you should replace E with your micro SD card letter.

If your computer still can't read your SD card after you try the above two methods, I am afraid you might need to purchase a new SD card as a replacement. SD cards fail over time. Like any other storage media, SD cards deterioriate over time depending on how much use it gets and where it is used.

Now, let's talking about another issue - why phone can't read SD card and how to solve it.

Part 2. How to Fix - SD Card Cannot Be Read by Phone

As we know, SD card is widely used to increase internal storage space of Android. (Here, I guess you might be interested in this post: 7 Methods to Increase Internal Storage Space of Android.)

Once you find any spot, you can wipe it gently by using cotton with alcohol or water, and then insert it in when it gets dry.

Situation 2. The wires inside of the slot rust or bend over.
Some phones support hot-plug. BUT, frequent plug-in and out makes the wires bend over, and then you will find that the SD card can't be read by phone. If the wires are at the same position, you should check the slot under light, and try to bend the wires back.

Situation 3. The slot is squeezed.

Situation 4. SD card is formatted improperly.
The forms of phones and computer formatting are different. For instance, FAT32 won't be read in Lenovo Motorola E680. Therefore, if your SD card is formatted with FAT32, you should reformat it to FAT16 to make E680 recognize it.

Attention: Formatting will delete all your data on SD card. Thus, you had better back up your data before formatting.

Situation 5. SD card gets infected with a virus or spyware.
If the SD card gets virus on computer, your phone will no longer be able to read it. The secret to solving this issue is this:
