Detect SD card in Qt linux

ivanicy

Hello!!

I need to detect a SD card inserted in the system in linux. I want to know the available storage for showing it in the interface.

How can I work with this, because I tried with QStorageInfo but it couldn't detect it.

Thank you very much!

Hi @ivanicy,

does Linux detect the SD card insertion?

What does dmesg --follow print while you insert the SD card?

Ubuntu recognises the sd card but, I don't know how to obtain its information with qt

Yeah, but it misses vital information. For me it looks like this:

Here you see, that a partition sdc was detected, and then the media was mounted into media/user/<device-id> (can be checked with mount).

Is that the case for you too?

Hi,

KDE's Solid library can help you there.
