I used to have a notification whenever the external SD card was in the tablet. Recently that notification has disappeared. How can I get this notification back.

I like this notification since I am able to eject the card from it without needing to go thru the settings menu to get to it.

What is interesting is that when I insert a different card the notification is back. I only am missing it for the original card. Last time I had this problem I factory reset my tablet. I would rather not have to do this again.

I searched for a solution but only found solutions to get rid of the notification, not the opposite. I tried to reboot my device but that didn't help.

Any suggestions will be greatly appreciated.

Change the volume serial number of the sd card.

There might be various ways to do it, this one worked for me when I had the same problem after touching "clear all" when displaying notifications.

Mount the SD card on a windows PC.

Note the drive letter of the sd card by opening a windows explorer window. For example let's say it was mounted as E:

In a command prompt window type the following command to find out the current volume id of the sd card, assuming the SD card is E: drive.

vol E: 

It should give you a number like 1234-5678

Download the Microsoft utility "volumeid" from this link at Microsoft:

Follow the instructions at the link for using the utility and give the SD card a new volume id.

Make sure you use the right drive letter, the drive letter of the SD card. You don't want to change your hard disk by mistake.

In a command prompt window, the syntax is:

volumeid E: 1234-5679

This will change the volume id of E: drive to 1234-5679

When you put the SD card back in you android device the device will think it's a different card and show the sd card mounted notification.

  • Great answer. Is there any way to do this in Linux? I don't always have access to a windows PC.

To add to @Morris's answer a way to do it in Linux (or on the Android device itself using Termux)

Run sudo blkid to find which device is the sd card. (On my device it was /dev/block/mmcblk1p1)

Now run sudo mlabel -i REPLACE-WITH-YOUR-SD-CARD-DEVICE -n (-n generates a random Serial Number you can use -N xxxxxxxx where you replace the x's with hex digits for the serial number you want see the man pages for mlabel).

The idea of using blkid and mlabel I took form Here! See JonathanS answer. and the exact way of writing the mlabel command to use the undocumented -i option I took from Here!

[I ran these commands on the tablet using termux and instead of sudo I ran it as superuser doing tsu -p and then eliminating the sudo part of the commands. I also needed to downgrade my libandroid-support.so library for it to work. I found that just doing tsudo (termux's version of sudo) gave me a large number of devices when I ran blkid and it was hard to figure out which one was the sd card.]


Another great solution, but your device must be rooted to be able to use this option (ASFAIK).

Use the sm tool sm forget [UUID | all] This makes the device forget the storage device with the given UUID or if you do all it forgets all the devices.

If your using Termux terminal emulator (as I am) you need to do tsu -p in order to be able to use the sm tool. If not you get an error. Basically what you need is for the LD_LIBRARY_PATH to point first to the android library path and -p prepends those paths BEFORE the termux library path.

I didn't try this in any other shell or terminal, but I'm assuming it should work there as well.
