Hi, did you can send the output of command "dmesg" when it happens?

Open a terminal e type "tail -f /var/log/kern.log". This command will block on terminal. Insert/mount/umount/detach/remove your HDD device. Get the output from terminal and paste in a website. Please do this.

how much partititons have on your HDD? 2 or +?

I can't get the same error on my machine with ubuntu 13.10 64bits

I have only one NTFS partition. Here you are the output from terminal that you asked for.I hope this will help.An I also want to mention that this problem is and when I use safely remove from nautilus.HDD spins off and then automatically mounts.

I just want to indicate that this problem is not affecting on any of usb flash drives that I try.Maybe this can help...?

I have the same problem with a flash drive. I tell bdin to detach the device but in 1-2 seconds it gets remounted automatically. This is not always reproducible though.

tail -f /var/log/kern.log shows how the device gets reconnected:

Feb 19 14:05:44 asylum kernel: [ 6300.784253] usb 2-3: USB disconnect, device number 17

Though it's not only bdin that shows this behavior.

udisks --detach /dev/sdb

leads to the same result: sometimes the device gets immediately reconnected and mounted.

Looks like this bug is quite old.

Hi all,

Bdin uses udisk dbus interface to manage devices. Any problem with udisk will affect it.
