eject kindle in linux (not unmount)

demoric · 07-24-2009, 05:13 PM

I use my Kindle in Ubuntu linux, and I have always had to disconnect the kindle from USB to be able to use the device to read or to test modifications.

In Windows if you eject the kindle it still charges over usb and allows you to use the device as a kindle. However in many linux distros the option you are shown in your GUI (Ubuntu's is Nautilus) is to un-mount the device which does not permit you to use the device to do anything while charging. If you want to still be able to read your kindle or use it's other features you have to use the eject command instead of unmount.

sudo eject /dev/sdb1

Please note: the device location may be different on your system to find the device open a teminal window and type: sudo fdisk -l and search for a device that uses a W95 FAT32 filesystem change the /dev pathway as needed. Also, some distros will not need the sudo aspect of the commmand line.

Thanks for sharing this very interesting find, it never crossed my mind to use eject for a USB device.

But are you sure the charging turns off when unmounting ? The charging LED still gives light after unmounting, here in KDE.

And the man page for eject says "If the device is currently mounted, it is unmounted before ejecting."

I'll update my original post to reflect to be more specific about the behaviors. I was misleading in the default behaviors the kindle doesn't stop charging when unmounted, but continues to show the usb icon image and states very clearly that if you want to use the kindle while charging to eject it. Unmounting the device alone doesn't permit you to use it while charging. I had just gotten so used to unplugging it to do updates and testing that my brain associated it with NOT charging.

But this post was really helpful in figuring out how to disconnect the kindle from my Linux system. Thanks.
