Comment 72 for bug 466575

The same error when I use the "remove safely drive" in Ubuntu 11.10 with a Kingston DataTraveler G2 (16 Gb) and with a Iomega external HDD (500 Gb). I only have the error with Nautilius, in Unity and LXDE it doesn't appear. I think that the first time that I saw this error was in version 8.10 or 9.04 with ext4, in 8.04 I can confirm that never has appeared me.

The error message is:

Unable to stop drive
