HDX connectivity
Posted by: jon h on 18 June 2008
I assume that HDX has an Ethernet port? It appears to be running Windows XP Embedded.
Is there a firewall in place? What protection does it have against local network denial of service attacks etc? Viruses?

Partly–but not entirely, not the poorly-managed £200 desktops that you often find in someone's home. BIG difference.
Sigh. Same base code base. Same core libraries. Same core kernel. Probably the same core driver set too. Same core Visual Studio runtime.
Yes, the problem is *unlikely* to come from within the HDX itself. Thats unless something gets injected -- remember SQL Slammer? HDX probably certainly has a DB engine in there to run the catalogue -- wonder which one?

Keep in mind, too, that you can crash a web server on a Linux appliance or any other device that provides Web services–how you approach this makes all of the difference.
I wasnt comparing against Linux. I was comparing against hard control firmware (and that in a box which has no ethernet port too )

Then I would infer that you would say that it matters not what happens in the digital domain of a cd player, because thats just ones and noughts too with a buffer thrown in for good measure????

Nope, I make no such claims. I think the two domains are different.
CDs played in a CD player have only one chance to get read as the CD spins. Each time you load/unload you might damage the CD. The CD player needs to handle this scenario in real time and correct any perceived read errors.
A HD is much different. Much less likely to sustain damage from being mis-handled by our big fat clumsy fingers. So one assumes no read errors from the HD once the file is copied there (the ripping process will handle that and ensure the HD file is 100% correct).
If you get read errors from a HD it's a corrupt file typically, yes? XL/Word/etc. files don't just randomly have bad bits in them each time they get read, resulting in a different stream each read -- I hope we agree on this?
The rate at which audio data needs to be read from the HD is low enough that any fragmentation will be a non-issue. If it isn't I would be hugely surprised. Assuming you are suggesting there might a timing issue with fragmentation.
I sincelerly hope you are not suggestion a data integrity issue due to fragmentation. Computers would not work if that was the case.
That's my take on it anyway.
