A while ago (and just yesterday as well) on the forums I've seen people posting that if you have a UMD inserted while you play hombrew, emulators, etc on your PSP, that it would constantly spin and eat up battery life, wear down the drive, and so on. I took it at face value, since it seemed halfway logical, and followed that advice.
Now it's starting to get annoying having to constantly take games in and out all the time, and I've just started using fastloader (with MY games; I'm completely against piracy), and if this theory is true, that might not be so good for my PSP, even in exchange for shorter loading times.
BUT, I decided to actually test this. So I turned the volume on my PSP completely off and inserted the PSP Video Demo Disc. I put the PSP right next to my ear and, sure enough, I hear the disc spinning up to speed. While it's doing that, I head over to the Game tab and start up Nester, and as the PSP title screen comes up I hear the UMD kick into full action. However, once I'm into the emulator I continue listening and after 10-12 seconds the drive sound cuts out sharply, and after 20 seconds there is complete silence. It even seems that I can hear the UMD rotations slowing down between the 10 and 20 second marks, until there were none. I messed around in there for a while, but the drive did not kick back into life until I went back to the Home menu. Next I tried the same test with fastloader (saying again, with MY games-Mercury, to be specific), and I get the exact same results: drive and spinning sounds for about 10 seconds, silence after 20. I've tried this in the various emulators, all to the same result. I have also repeated this process with Lumines inserted in the PSP, to the same results.
So I wanted to bounce this off you guys. Is what I'm hearing leading me to the correct conclusion? Is the "non-stop spinning" idea just a myth? Or am I missing something? It seems to me that if the UMD were spinning so wildly and eating up so much power, it would be impossible for it to run completely silent.
Maybe you guys could try this too :) Tell me what you think.
