External SD card not showing in Explorer

Raymond Lin · 11 Mar 2023 at 15:12

I have this 32G SD card, not showing up in Explorer.

However, it shows up in Disk Management. It also shows up in my Mac OS.

(ps it is a Macbook, but another SD card shows up fine in explorer)

Things I've tried

1 - Different USB ports
2 - Putting the MicroSD card into the USB Hub's micro SD port
3 - Putting Micro SD card into adaptor (SD card size) into SD card port in the USB hub
4 - Different SD card in the same USB hub shows up
5 - The 32G card shows up fine in the iMac
6 - Mini Partition shows no corruption on the card.

I took a screenshot to show that on the left is Explorer and right is Disk Manager, what could be causing this?

looks like no drive letter assigned?
tried right clicking on it
then change/assign drive letter?

Backup any files on it, then use Diskpart to clean the drive and create a new partition.

You could try using Sd Card Formatter -

SD Memory Card Formatter for Windows/Mac | SD Association

Imaging all that time spent formatting the drive it it didn’t need to be.

To be fair, I suggested what I did because of all the extra partitions on it.
