Eject removable media (build in SD card reader) - reject but auto come back within second

andrew_ysk · September 22, 2020, 9:47pm

I just encounter this issue.
When i eject a usb removeable device, it reconnect the usb device back straight away , within milisecond. That means i can never able properly eject a usb removable device.

$ lsblk

This photo shows the Removeable Media was just ejected, but it reconnected back. hence got 2 7.4GiB Removable Media.

What is that? Is it a memory card? What hardware is it attached to?

andrew_ysk · September 22, 2020, 10:10pm

SD card

dalto · September 22, 2020, 10:12pm

What hardware are you using to connect it?

andrew_ysk · September 22, 2020, 10:16pm

Build in card reader.
I don’t know which one.

So…we started with this problem:

But it seems like you are not using a USB device at all. You are using an internal card reader. That is a totally different thing.

andrew_ysk · September 23, 2020, 10:19pm

Huh ?
Sorry, i thought all devices are either PCI or USB.
So, any idea how to overcome this problem ? i can’t find anything related to this in internet. Or maybe i type a no good keyword for search.
Anyway, to search problem on endea os, the problem is there are less user uses endea… so… i have to use arch linux as search keyword in place of endea os ?

A lot of command from internet does not exist here in endea linux.

andrew_ysk · September 23, 2020, 10:23pm

I found this command, but no idea how to use it to solve the problem.

This has nothing to do with your original question or problem as you put it. You were using eject for usb devices. An sd card is not a usb device. That’s the end of it. You have now turned it into something else that it isn’t. Udisks is for another purpose which you should already know if you searched about this and are using the command.

@andrew_ysk
I don’t think a removable sd card can be ejected like a usb. It can be unmounted i think but not ejected. So udisks2 is already installed on EndeasvourOS. I see what you are trying to do but I’m not sure i understand exactly? You can unmount an sd card and remove it?

Do you not eject any storage device before take them out ? if just take them out without eject them properly will it causes harm to data if not careful enough (data transfering in background ) ?

If it is not need to be eject, why is there a eject button for the SD card storage ? Screenshot_20200924_073703

When you “eject” a drive, you are really just unmounting it. You can prove this by checking for the folder the drive was mounted to after clicking eject. It should be gone or have nothing in it. So in KDE unlike some other solutions, when you eject a drive, you could technically just mount it again without issues. Unmounting a drive is sufficient to prevent against data loss. Once you unmount it, you can pull it, or in the case of your SD card, you can remove it.

It is not all that easy sometime.
I have experienced on manjaro
unable to umount a drive
and
after umount; when replug in usb stick, it won’t mount back anymore, until i restart pc.
But it works good on Endea os:
