Format SD card

[CDR0224]

How do I format an SD card?

I can see it in Dolphin under devices and it is mounted, but when I right-click on it, there is no "format" option.
In Partition Manager, same thing, no way to format it.

Do I have to first unlock something?

You can't format a mounted file system. In other words, if it's mounted, it already has a file system on it.

Here, when I insert a removable device - sdcard or USB - it appears in Dolphin but is not automatically mounted. When I right-click, Dolphin offers "Reformat" as an option.

KDE Partition Manager should be able to do this also.

Hmm, in Dolphin, when I don't mount it, it automatically mounts when I left-click on it.
Annoyingly, if I unmount it, it disappears from the removable devices and I have to unplug/plug it to see it again.

When I don't mount it, but instead first right-click, there is no format option either.

I know you can format a USB drive using Gparted. Not sure about the rest.

on my machine KDE 25.10 if i unmont the sd drive it allows right clicking and first entery in the list is reformat. So I'm wondering if you have changed anything since installing, Have you changed any setting in Dolphin?

So don't left-click on it. Hover over it and right-click instead.

You have to unmout it first you can not format a mounted drive. Other alternative would be to install gparted and us it to format the disk but you have to be very sure your formating the correct one.

A drive can not be mounted if you want to format it. If the drive is already mounted; and that is very likely the case with your SSD Card when you insert it; then you must unmount it.

Normally, when you plug-in a drive device, a pop-up notifier appears: Disks & Devices; that identifies the device with Mount and Open V shown. Click on the V and you are presented with options. For me, they are:

Mount
Reformat or Edit with Partition Manager
Download Photos with Gwenview

You can click on Reformat or Edit with Partition Manager.
