Today I have just bought new card reader ELECOM MR3-A006, but when i insert microSDHC card, windows 8 as well as Windows Vista shows removable drive but does not detect media. However my cellphone detect this media and it is working fine. In Explorer it shows drive but when i try to open, it display "Please Insert Disk into removable drive". This worked for me: -Run Regedit.exe: • Go to the following key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography\Calais. -Check the permissions for LOCAL SERVICE (if not there, add it). Make it "Full Control": • Right-click on the key (Calais) and select "Permissions" from the pop-up menu. • Click on LOCAL SERVICE to select it. from your smart card or token). (i.e. Write the Unlock Code down now Please note that the Unlock Code is a 16 digit hexadecimal number. Valid characters are 0-9 and A-F; there are no letter “O”s, for example and be careful not to mistake a “B” for an “8” and vice-versa, etc.) Then click the Finish button. Method 1: I suggest you to plug in the SD card reader and run the hardware device troubleshooter and check if it helps. Follow the below steps: 1. Type troubleshooting in the search bar. 2. Select Troubleshooting. 3. Select View all on the top left corner. 1. Right click on the driver setup file and select “Properties”. 2. Select “Compatibility” Tab. 3. Make a check mark next to Run this program in “Compatibility mode” and select Windows10 from the drop down list. 4. Then click on “Apply” and “Ok” option. 5. My SmartMedia memory card reader does not AutoPlay when i first plug in a memory card. if i remove the memory card, then re-insert it, AutoPlay works fine. I assumed it was the card reader, so i purchased a NEW one. It does the exact same thing. I've flashed my BIOS to A02 and fully removed and re-installed the card-reader drivers and registry .

no smart card inserted first media
