Tips

  • If you've inserted the card and the Mount SD card is grayed out and is asking you to insert an SD card, your card may be damaged and you'll need to replace it.
  • Alternatively, if your phone is running Android 4.4 Kit Kat, you may not be able to use an SD card anymore. Some owners report that SD card support has been dropped in your phone's latest software update.

Warnings

  • Do not remove the card during the formatting or mounting processes. Doing so will result in corrupt data and could render the card useless.

Questions and Answers

I formatted a new SD card. The mount button flashes and then goes back to unmount?

Does not show new card, still shows only 16GB not 32.

Some Galaxy S4 users have called Samsung for a solution to this problem. Samsung has told a number of owners that the following procedure may fix the mount and unmount SD card issue:

  • Remove and reinsert the SD card.
  • Turn your phone off. Remove the battery.
  • Wait for 30 seconds and put the battery back in.
  • Turn the phone on.

If your Samsung Galaxy S4 still can't mount its SD card, take the card back and exchange it for a new one. It's possible that this SD card is broken. If the phone still can't recognize the SD card, call Samsung and tell them about the issue you're having. You may have to schedule a repair for your Galaxy S4, or you may be running Android 4.4 Kit Kat, which has dropped support for SD cards for some Galaxy S4 owners.

What would cause an SD card in your phone to become erased/unusable?

Had a 64 GB Samsung SD card in my Galaxy 4S cellphone for a couple of months. I had 35 GB of music on the card and had been playing the music from the phone. Was using a song as my ringtone. Then today there was no ring tone. When I looked at the settings the ringtone chosen was silent. When I went to re-choose the song for the ringtone, I discovered that the SD card was blank. Took it out of the phone and put it in my computer and it said it needed to be formatted in order to be used.

It asks for a confirmation PIN to reformat, what is the default PIN?

Asks for a confirmation PIN to reformat, what is the default PIN?

Either enter your lock-screen PIN or alternative PIN (if your phone is locked otherwise). You can also try the last four digits of your phone or "1234" or "1111". If none of these work, then it can be owing to the previous encryption of the microSD card.

The easiest way is to format the microSD card using a PC. Put the microSD card into a card reader (use an adapter if necessary). Then, press the Windows key and type "create and format hard disk partitions". Press "Enter". Locate the "Disk" on the list within the lower half of the Disk Management window. Right-click it and select "Mark Partition as Active" if needed. Then, "Format..." and select and the "exFAT" file system with the lowest sector size. After formatting the microSD card, it should become usable on your smartphone.

What you can do is to test them on a computer. Take them out of your phone and insert them into an SD adapter for your card reader (if you have one). Put them into your PC and see if you can read the cards. If you do, then the cards are fine. You will need to format the card to exFAT with any sector size from your computer. If that does not work still, try formatting it to FAT32 with the biggest sector size for maximum compatibility (although S4 do support exFAT). Also, make sure that you push the SD card fully and correctly into the microSD slot of your phone. Here is the article on how to do that: "How to insert and remove the memory card of Samsung GALAXY S4".

LAPTOP (RIGHT-CLICK) ON TAB 4 ICON PRESENTS NO "FORMAT.." OPTION?

My issue is there is a hidden file (.android_secure) on my microSD Card that "failed to delete" when I attempt it manually or when I format using the Tab's Format SD card route. My laptop doesn't have a facility to directly insert a microSD Card into it, so I'm trying to use my Laptop>Format route. When I connect my Galaxy Tab 4 to my laptop I click on the Galaxy Tab 4 Icon and I see two drives: Card and Device. The USB is mounted as Media Device (MTP). I highlight, then right-click, Card and it presents me with:. Open. Open in New Window. Pin to Start. Properties. As you can see no "Format.." option. The file system identifies it as Generic Hierarchical. . . How do I enable "Format.." method on my HP Laptop running Windows 8.1?. Thank you. I have tried: Mounting as Media Device and then Camera (PTP). No change.. I think it was caused by: I have no idea. When I connect any of my mobile phones to the laptop, I get the "Format.." option on the right-click of the device's icon.
