Is there a way of shutting down all these drives with just one or two clicks then powering them down without having to power down the PC? I really want to cut my electricity usage as well as extend the useful lives of the drives.

Might be a pain if you go for a linux solution due to needing to reformat the disks (unless you use linux already of course) but I reckon that'd be the best solution.

I don't want to go to any great expense so I think I'll simply go back to ejecting each in turn then turning off.
If only there was software about that you could select which drives to eject and then one click automatically did each in turn. Then it would just be a matter of turning the drives off in one go as they're all connected in chain to 3 4-way adaptors.

..or get a tool to it for you. RemoveDrive doesn't appear to support wildcards or multiple entries however you could write a batch file with repeated instances of RemoveDrive being called for each drive you want to dump the cache on and prepare for removal.
If you're using Linux just run the sync command and all outstanding writes will be forced; conclusion of the command indicates completion at which point the drives can be removed or powered down. [Edit: I see now you did specify WIndows but I'll leave this here for reference]

That's not a good way to do it, the equivalent command line to safely remove a usb drive is to do "udisks --unmount /dev/sdb1" then "udisks --detach /dev/sdb". The "udisks --detach" may well make the drive power down, like XP, but unlike Vista or later.

I've never heard of udisks before and it looks like it might be quite a new tool? It doesn't appear in Debian Lenny which was released in 2009 hence a good few years after the Linux kernel first started supporting USB disks.

Well the rpm changelog for udisks starts at Dec 2 2009, but it was called "DeviceKit-disks" or devkit-disks for the command name for a little while before then. It replaced hal.
It might be better to have the disk shut itself down rather than just flicking the power switch (if it has one).

I can't argue with that, although this can sometimes be tricky over USB, seemingly depending on the particular chipset and other aspects of the enclosure hardware being used.
