Odd. Latest firmware, I assume?

IIRC the external slot supports more voltages than the internal.

Make sure that the battery cover is closed, and also that you haven't lost that little magnet which tells the N800 the cover is closed.

It's a little square black thing some 2.5x3mm sitting in a depression between the latch and the corner of the piece of metal on the inside of the cover.

OMG! I have had the same problem for months now. I just looked, and sure enough, the magnet is missing!! It seemed like the case was a little loose, but I had no idea that might the problem.

Question is, how to get another one?:eek:

uhm.. Is it not this cover? http://www.mytrendyphone.no/shop/bat...kia-6671p.html

If it is attached to the battery cover it is possible to buy it separate

You could try to email salg@mytrendyphone.no ..

And even when it is a Norwegian e-mail.. Norwegians write/understand English also ;)

Thankfully, I won't have to answer this question. I went to look carefully and there, tucked away inside just out of sight (threatening to go deeper into the machine) was the magnet! I pulled it out with tweezers, re-mounted it and voila, I 'have' an internal memory card again!

[rant]

Now, I love my N800, and I've been careful about how I criticize the product because I do believe in it so much, but I have to say, this is one of the very worst design flaws I've ever seen in any product.

What logical reason can there be for disabling the sd card when the little magnet is not in place? What is the function of the magnet? To hold the cover or 'enable' the SD card?

This is a serious usability issue, and it makes me wonder who was in the hardware specs review meeting where someone said,

"I think we should make it so that if the magnet on the back cover isn't in contact with the circuit board, then the internal SD card should be inaccessible. After all, it has to be that way because...."

Right. Engineers. I do hope this 'feature' hasn't been 'continued' in the N810:cool:

Re: Internal SD card slot stopped working?
 
The magnet is there for a quite important reason: The N800 _must_ detect that you may be about to remove the SD card, before you actually do it. This is because it must unmount the card, which means to write any non-written data to the card first to avoid card corruption. This takes a non-zero amount of time.
When you close the cover it re-mounts the card.

This could of course have been done by some other way than a magnet, e.g. by a mechanical cover-closed detector, but that involves moving parts which sooner or later may stop working. A magnet is a quite elegant solution, if only the glue was a bit better..

For the external slot there _is_ a mechanical sensor, connected with the little latch that closes the SD slot.

Thanks, TA for this explanation. It does make sense to un-mount the card to avoid corrupting it;)

I guess my rant should be revised to place the blame on the person who decided that glue was the best way to mount the elegant little magnet! Or perhaps it is the person who ordered the cheap glue!

New N800 owner.

Hope this helps someone. The documentation gives specific info on how to install the external, but has no mention of how to install the internal memory card. No markings on the slot itself. Eyeballed the connection, and figured out how to position the card. Beveled edge on the left, and contacts facing inward. It firmly attached at the bottom contacts, but was flopping around at the top. Something was wrong. I noticed the metal latch above the card with a small arrow pointed downward. Carefully slid down the latch and the card was secure.

Reassembled unit.

Checked File Manager, and my new internal SD card was not recognized (grayed out).

I fired up the trusty SEARCH button on this forum, and found this thread. Popped off the back of the case again - square depression with NO magnet. Not even a sign of any dried glue on the plastic. After removing the SD card, and peering carefully into the NIT, I discovered my magnet on its journey halfway into the depths of the logic board. (Saw it
through the small rectangular opening in the metal to the top right of the card slot adjacent to the battery).

First I tried gently shaking the unit in a downward direction. No help at all as it did not move. Then I
carefully attempted to grab the magnet with a thin tweezer.

DAMN, pushed it further into the unit!

Finally I used a very thin plastic cable tie to manipulate the magnet downward. I was successful in bending and pushing the cable tie through the very TOP of the metal shield through a very small opening adjacent to the plastic case. (Directly above the rectangular opening referenced above). After pushing it down enough I could grab it with the tweezers.

Once I had that sucker, I put a small dab of good glue on both it and into the depression on the back cover. Re-inserted the SD card, slid down the metal latch, popped the cover back on, and VOILA, new internal memory.

Thanks for all for contributing to this board.
Love the N800, but that glue they used for the
magnet is worthless.
