It seems I made a mistake when copying text. I have = 1 for them. I'm sorry.

I made a big work (4 usb flashes, 1 USB HDD + 3 laptops, 1 PC). I tested Ubuntu 12.04 LTS, Ubuntu 13.04, Fedora 18, OpenSuse 12.3.
The results are not good: a have only one flash, which can be detached completely (with poweroff) with the newest Ubuntu 13.04.

The report is located in Google Docs, you can download and explore it (https://docs.google.com/spreadsheet/ccc?key=0Ao5e713Ig9g_dHJBalI2b09TQ2ZNOHJOQnhFbEVXaXc&usp=sharing).
On first sheet I wrote a summary for my devices (name, fdisk -l, lsusb, udisksctl dump, cat /sys/block/sdc/removable, comment).
On the second sheet I collected test results - on different machines, distros, with safely remove test by Nautilus, udisks and Unity.

I think we need more test results.
It's unbelievable, that almost all modern Linux distributions can't safely remove USB-flashes and spin down USB-HDDs.
