That's interesting, found out that the hubble uses a zilog Z-80 equivalent processor with 386 co-processor for its "brains".

Well, when I was working for FSL micro. They are producing microcontroller for cars much like the HC11. For all these chips, all striving for 0 dppm (defect part per million). Of course it is not achievable but manage to get it to 5 dppm in which is quite good. I can tell you that Japanese auto customer, like to use very very old microcontroller like 10-15 yrs old model. Why do they do this because, these are more stable and simple chips in which is more reliable. US auto customer however uses the latest chips, and lots of them in a single car, in turn

sometime stall the car hehehe. We did have military and aircraft customer much like the NASA, in which is tough. All electronics goes through a very tough stress to ensure their quality before they are use. That's why they would not want to use something like 1000dppm (end user product) HDD for space craft ..

Yeah, one thing about space "computers" is that radiation hardening, reliability and power efficiency are more important than performance.

No it won't. It's pointless to even have a thread like this. Ask a harddrive manufacturer a question like this, not a bunch of geeks on a computer forum. Even though the answer is no, you should only refer a question like that to an engineer who designs harddrives.

It's just a fun thread for people to express their views on whether it is possible.

And frankly, it has been proven that yes, you CAN run a hard disk drive that is immersed in non-conductive liquid.

where the proof ? have a link ?

Hmm the article was never posted, but there's a video showing it.

I guess he didn't even read the thread.

Funny that you are really a WD engineer.

Sorry, the article hasn't been posted. Will get right down to it.
