Actually this is an MS-DOS binary, which might complicate things for you
if you no longer have a working dos environment like a bootable floppy
or a stick installation. This is why I posted the wiki link: the article
explains how to create a bootable freedos image with the exe included.
Since I still had a working MS-DOS 6.22 floppy I used that one, but the
wiki howto ("Verwendung von FreeDOS") looks straightforward to me as well.
The binary archive can be downloaded from the wd support site  there
is a text file inside that explains the update procedure.
Do you have any advices about the Samsung drives in the mdadm raid? Can I
put them to sleep normally or do I have to tell mdadm that it has to spin
down the drives?
This seems to be a controversial topic - some people report no problems
with md raid standby, some disagree because mdraid does not handle it
well should one array member sleep and another member doesn't.
Maybe you can choose a solution where you unmount the array before you
put them to sleep, just to be on the save side? I never used this, since
I prefer to shutdown a server on inactivity, and wake it up again using
WOL or acpi wakeup.
