A mpeg file can be copied over 100 times faster than it takes to play it.
The disk's speed therefore seems to be so much faster than needed for video,
why is it even necessary to speed it up by reducing the error-correction?

Because PVRs don't just play; they simultaneously record, from two
sources on twin-tuner models, and have features such as live pause and
action replay. So the disk may be having to deal with simultaneous
multiple streams of data.

Because the worst of the retrys on error correction with writes can see
a significant glitch in the video file. When the error correction isnt as
aggressive, the glitch is much less noticeable.

That's only 3 or 4 times the load, but I can see that thrashing and
re-seeking would slow it down a lot more.

Constant thrashing for long periods causes wear and heating too, so I wonder
if they are designed for that.

!No comprende!

Or, I'll take a stab at an English translation:

"Spanish is the language spoken in more of the world,
John."

("More" is accurate..."most" isn't.)

I have just ordered one of these AV-GP drives as I was able to find one fairly cheap and needed a smaller drive to run my operating system off. Initially, I was sucked on by the low temperature and quicker read speeds, however have been put of a little by threads such as these on the net. Could anyone confirm whether or not they have used one of these drives as a boot drive within a computer? If so, have you noticed any behavioural characteristics different to, say, any other HDD? If the drive is unsuitable, i'd rather not bother removing it from the packaging and sort out a return a.s.a.p.

Fortunately these should be more expensive and not
show up in cheap computers. But some people will
recycle them and run into problems.

I have been scavenging AV disks from PVRs for about 2 years. None gave a problem.
But I always check the SMART data first. Some had a disturbing maximum temperature
(up to 80 Celcius). Perhaps somebody left the TV magazine on top, blocking the
vents.
