Hello,

I hope you can help here. I've just started working for a new employer and
one of the first projects I have is to develop and interface/reader for
Sony's memory cards. CF and SD cards, IDE and SCSI I've done before and the
information was pretty much readily available. In this case however, Sony's
protocols for communication with their cards at an embedded level is a bit
obscure and non-existant.

The MG technology I believe is an encryption algorithm applied to the cards
to 'lock' them, it was originally pushed with the Playstation 2 as allowing
the storage of online customer information, bank account details, passwords
etc.

Is the MG function always enabled? Because if it is I'm dead in the water
from the moment go without that algorithm.

Would anyone have any experience in interfacing with these cards, please any
info? It'd help me out loads as I'm just sitting here doing all of the
other background work surrounding the project in the meantime.

Any help very much appreciated,

Aly :-)

Hi again Aly...

Did a bit of a search, but the news doesn't look good.

http://forum.dbpoweramp.com/showthread.php?t=2377

Not strictly related to your issue, but contains discussion on the
encryption system, which seems to fall into the "pay as a million in
licence fees, or we sue you to death" catregory.

Sorry...

It's not in the least obscure; it's merely unavailable without signing
a license. You also cannot use the Memory Stick compatibility logo
without such a license.

History: In 1999 or thereabouts, when Memory Stick was emerging, Sony
made 85% of the interface documentation public and a license to use
Memory Stick was free for the asking. A few years later, they clamped
down and made it something like SD - you had to pay a lot to get in the
club. At that time they hid all the public documentation (though if you
want a copy, I can give you one).

I don't have the MagicGate specification and couldn't disclose it if I
did. But the specification for vanilla Memory Stick is written in such
a way as to imply that the DRM feature isn't turned on until you use
it. As further evidence in support of this, modern Memory Stick media
work with cameras designed for pre-MagicGate sticks.

That was certainly uncalled for Rich.

What in the posting smells of bullshit to you?

But now that I review your posting, your signal to
noise ratio is less than 10%

Is this a pot-and-kettle thing?
