Note 4 Not Reading microSD Card

Problem: My sd card is not working I have a 32g and I have been using it for a while and a couple days it would not want to save anything and it won’t show me my pics and wants me to reformat it and I don’t want to losses my pictures thanks for your help.

Solution: You should let another device read your microSD card and check if the data can be retrieved. To do this, turn off your phone and take out the microSD card. Using a card reader or microSD card adapter connect your microSD card to a computer. Browse the contents of the card using the file explorer of your computer. If you can see the photos then there is still chance to retrieve them. Copy all of your data from the card to the computer. Once you have copied everything format the microSD card. You can then insert the card back to your phone and check if you can save data on it.

If your computer cannot read the microSD card then it may already be corrupt.

Note 4 With 256GB microSD Card

Problem: Bought a new 256gb Samsung sd card. Trying to transfer files from 32gb sd card to new 256 gb sd card on my mom’s mac. Says can’t read  some of the files. Please assist, oh is it true that the note 4 can only use 128 gb sd card? Thanks for your time.

Solution: The largest microSD card capacity that the Note 4 supports is up to 128GB. This means that you won’t be able to use the 256GB microSD card on the device.

Regarding the transfer of data from the 32GB card to 256GB card how are you connecting both cards? Are you connecting the phone using a USB cord to the computer with the 256GB card connected using a card reader? If this is the case then try connecting both cards to your computer using a card reader then proceed with the file transfer.

Note 4 Copying Contents To New microSD Card

Problem: I have a rather old (4 years) SD card that I store all my photos and music on, as well as apps. I recently backed up all the photos and music to a separate hard drive. Since I have been reading lately that you can expect to get 2 years of use from an SD card before you might see some problems. So the question is this. If I by a new SD card, will all the photos and music go to the right place when I copy them from the hard drive to the newly installed SD card?  Hope you can help. I’m kind of old and moderately tech savvy. Thanks

Solution: If you copied the entire contents of your old microSD card to a folder in your computer then copy the contents of this folder to the new microSD card the files and folders will be in the right place.
