What will happen if I format my androids sd card?

[Ariianna]

I plugged my android into my computer and then when i went to take it out I forgot to unmount it. Now my sd card is asking me to reformat it since it is damaged. If i do format it will I lose my contacts?

I also have apps on there that I would like to keep. Is there anything I can do to save them?
I copied all my pictures from the sd card to files on my computer so ill just readd them to my phone later, but there is an app with information I would like to keep and It is not listed on the sd card files when I open it on my computer.
Does that mean I cant save it?

Everything on the sd will be erased.

So, If there is an app that is not listed on the sd then it will still be on the phone?

 

[Ryistech]

I believe so. If it wasn't saved on the sd then it should be fine.

but dont forget i dont know if you do this but you can save all of your contacts to your gmail account so you wouldnt have to worry about them in the future from switching to phones or having to buy a new sd card because it corrupted or something

Contacts aren't saved to the sd card, you wont lose those. You will lose any pictures, music, video, etc, and any apps that were moved to or installed to the sd card will have to be re-installed.

You really need to "eject" the card from your PC to ensure that the PC is done writing to the card before you disconnect. Unmounting from the device won't prevent what you experienced as your device doesn't know what's going on with the SD card when it is mounted to a PC. If you tell your device to unmount without ejecting from the PC first the device will unmount regardless of what your PC is or isn't doing to the SD card and you risk running into this very problem.
