the power dongles come to ruin our way of life

I recently moved.

I found enough of the power supplies for USB disk enclosures to power on the most crucial disks (read: the ones attached to mythtv).

However, I have a disk I use for offsite backups. I need to find the dongle for it. Can I find it? No, of course not. I’m user it’s one of these 5 boxes of misc office crap (including *lots* of cables).

Why can’t we just have a standard USB disk enclosure power cable?

Please, pretty please.
