Wikipedia says that shiva is the hindu deity known as the "Destroyer". Interesting that GlobalScale choose "sheeva" as the name for their first plug generation. Sounds a bit like a self-fulfilling prophecy… The internet is full of stories and images like the one on the left - "exploded" power supply units cause by… nobody knows for sure. It seems to be that attaching passive usb devices is not a good idea. My harddrive was self-powered but I had also a dvb-t card attached on a non-active usb hub… bad.
As a proper replacement PSU shipped by NewIT would be available only in late February I crafted a replacement together by myself from an unused ac/dc adapter as an external powersupply. I am always a bit scared by hardware-modding but stripping and connecting the wires was easy after finding descriptions like this so my sheeva raised from the death - lets see how long this will last. Next week I will properly shop for an active hub to decrease the PSU risk further. At some point I should also get a real replacement PSU, but at least I can wait and search now for one where the cost isn't doubled (or even more) by shipping costs… (Why is there no German based distributor, who has one available?)
