>A) With no internal power supply the sheeva runs with no noticeable heat..... which is a real bonus

Well, my plug still gets quite warm (with an external PSU). I guess this is from CPU. I also noticed a heat sink inside (over RAM/CPU).

The ~10W of energy must go somewhere.

But the external 5v 2a PSU stays very cool (Delta Electronics).

3  Hardware and U-Boot firmware / Hardware / Re: SheevaPlug USB Power Supply problems. Can it Drive a USB Ext Disk? on: September 18, 2010, 06:04:10 AM
Thanks guys for all the info. Especially the last post with the info about WD scorpio blue spin-up options. Very useful!

My setup is like this : the plug, Debian OS on 8gb flash drive + attached 2.5 inch usb hard drive (500gb WDC). I bought it in Nov 2009 and running torrent box (transmissiond) 24h/7.

Here's my story:

-Noticed strange sounds coming from the HD about 2 months ago. Like others suspected the disk is becoming instable. (wrong!)
-This went on for a few weeks, sometimes with no noise. Absolutely no r/w problems with the disk.
-Then, last week disk has read problems. Ok, I thought, the disk is ready for RMA. But to my surprise everything was readable on a Win7 box. (I made a full backup just in case)
-I googled and found this forum with all the folks posting their similar experience. (Power of the web)
-Opened the sheevaplug and found the PSU intact (no cap has blown), but close: One of the caps was bulging!!
-Went down to an electronic hw store and got the 5V 2A Delta Electronics PSU. This is now external and working very well with my setup.

Anyway, what I like to say is, find an external PSU and don't support this crappy company called Globalscale Tech.!

First, the sell you a shitty PSU inside the plug, then they make you pay for another 10usd for a spare PSU (who knows when you will get this and how long it will work with your existing plug).

Customer is supposed to be king! This company doesn't give a damn about you and keeps you guessing whats going on for weeks (when I placed my order).

I got my Delta Electronics (this is a very reputable manufacturer) PSU for less than 5usd!

For me one thing is clear: I'll never deal with those guys (Globalscale Tech) again.

Have fun plugging!
cheers
