I recently purchased a Kodac 128mg sd card
and transfered a back up of my 8mg card using the USB Reader/Writer with no problem
but I found that the Jukebox would not recognise the card when I tried to do a check out. I found that the Panasonic card
has an extra contact. It would seem that only
the Panasonic card will work with Jukebox.
Has anybody else found this problem?.
Brian.

never tried another make of card yet... does formatting the card in jukebox before doing the restore make any difference?

I Have done a format in the keyboard
and have used the reader/writer to write
a back up but cannot use check out or format
when useing Jukebox. When the sd button is
pressed I get the message sd card not found.
I appreciate your help.
regards
Brian.

like I say I've never tried another make of card yet, and don't like the sound of this missing contact at all...

I ask about the format because you don't need sd selected to format. You can leave pc as the selection and try a format from the settings menu? If that doesn't work, maybe it's money back time?

Hi Alec
Thanks for your reply.
If you look at the contact points in the
reader/writer you will see six in a row
and a seventh on the right side a little
lower which matches with the Panasonic card.
It appears that other makes dont make contact
with this point. If this is so I feel that
Matshushita should state this fact, and save
people like me the trouble of returning them,
I tried other sd cards from digital cameras
with the same result. I have managed to get
my money back, and trying to get a Panasonic
card but two dealers in my aria have had them on order for weeks. Not good news, I think kn7000 owners should be warned.

hmm... yes this should be pointed out. All my other stuff is compact flash (with one unfortunate smart media ) so this is worth knowing. Glad you got your money back.

Thanks for this very interesting information. Does this finding have implications about third party SD card readers as well? Specifically, must a KN 7000 user use both Panasonic cards and readers as opposed to third party products?

I have 3 different makes of SD card and had no problems with any of them. They are Panasonic, I.O Data and SanDisk. All contacts look identical and are actually gold plated edge contacts on the PCB. None have a missing contact. Having said this, I have only used them in the KN7000 not the Card reader.

well so far, the theory is that the problem is the encryption for digital audio, which goes through the card reader, but if you have the same number of contacts on your cards, perhaps the key is this extra (missing on kodak card) contact, so these cards may work for audio??

I think lexar also mention digital music players for their sd cards. If they mention digital music players this must include the panasonic players. And if the panasonic players are loaded through jukebox or a derivative program, maybe lexar also should work?

I was just about to order a Lexar 128 Meg SD card. Does anyone have working experience with this brand?

I have Panasonic and Sandisk SD cards.
I used them in the kn7000 and in the cardreader and had no problem.
So you can be sure that Sandisk works.

Brian, are you sure that the Kodak card is not a multimedia card? I believe they look exactly the same as a SD card and will fit the slot but do not meet the SD card spec and they do not have a data protect switch.

I've only seen a max of 64 MB ever advertised for multimedia, so thought this at first too, but assumed that since this Kodak card was 128 it must be sd? multimedia cards are the same size, but slightly thinner, and probably will work for technics and midi but probably not for audio. I would guess they may not have this extra contact though?

Interestingly SanDisk also specifically mention digital audio for their sd cards, and Alain's works fine, so maybe the lexar looks more promising?

Yes Alec you were correct, the Kodak card
was Multimedia and in my ignorance I asumed
it was ok for digital music, we live and learn. I will try the other makes recomended
but because of the plastic packaging its
impossible to to see the contacts on the
back of the cards. Many thanks to all who
responded.
Brian.

"I've only seen a max of 64 MB ever advertised for multimedia"

Lexar also has a 128Meg Multimedia Card. And, many adds say they will work for SD functions. That is true for some, but not all SD functions. They are priced about the same as SD so there is no advantage in buying them for the KN7000. I guess the moral is, don't try to use Multimedia as a substitute for SD.

Continuing the sad story. Today I bought
a 32mg lexar card and was told it should
work fine as it says its ok for mp3 players.
But when I get home I see it only has 6
contacts and the results are the same.
On the Jukebox screen with the cd button
pressed the settings button will not recognise the card also the cd button when pressed.
I have now given up and ordered a Panasonic
card from my keyboard shop and hope to get
it some time next month.
Thanks for all your comments.
Brian.

the 128 multimedia must be quite recent then. Multimedia does not have the encryption technology that audio has on sd, and it would seem reasonable to assume it will not have a great lifetime ahead as a format, because sd has far larger capacities available and coming on line. Unless it remains as a cheaper sibling of sd.
I thought about getting some just for technics or midi format if the prices were much less than sd, but in the long run losing the opportunity for digital audio is probably not worth it.

the lexar story is peculiar because here http://www.memorysuppliers.com/san12secdigs.html they specifically talk of use for digital audio players and crytographic security for copyrighted data, which you would assume would make it ok for the card reader??
multimedia specs only mention uses for cameras, camcorders, phones and pdas, not digital music players.

Brian, Have a look here - I got delivery within two days from both : http://www.7dayshop.com/catalog/

Many thanks Bill I have mailed my order
for a 64mg Sandisc card. Looking at the illustration it has the right amount of
contacts and a write protection switch.
Isnt it nice to have such good friends even
If we never meet.
All the best,
Brian.

That's good news Brian.

"the lexar story is peculiar"

Alec, what Brian described above is another Multimedia card, this time a 32 Meg from Lexar instead of Kodak. I have no doubt that the Lexar SD cards will work fine.

well, yes, that would explain it. Maybe the moral of the story is don't believe everything the salesman tells you...

The lexar SD is written up as SDMI compliant, so there is no reason it should not work for audio. So we have panasonic, sandisk, lexar, and i/o as potential sources (the i/o spec also mentions SDMI compliant). I've also seen toshiba sold as transcend, but these were expensive.

Just bought a sd card 128 mb Kingston also no problems.
I restored a back-up off 35 mb to this card in only a few minutes.
