4GB SD card confirmed functional on the Nokia N800


I saw this ad and marched my happy self down to Fry's to pick it up. What can I say? It works? I have a half gig of MP3s on there now and will be loading up more shortly. If only I could preserve my playlists from iTunes and use the N800 to replace my 4GB iPod nano...
It reports 3.8 GB available. I am going to do more testing over the next couple days to see if I have any issues. Note that this is NOT an SDHC card. The nice people at SanDisk at CES loaned me a tested and functional 4GB SDHC card and it was not recognized by the N800. Reader (and kernel patcher) Philip Langdale reports that SDHC support is only a kernel patch away, so we can hope Nokia tests, verifies, and implements this for the next firmware upgrade.

Yes, I've used a 4GB Transcend SD card for close to a week as an internal memory card on my N800.

Haven't done any specific testing beyond normal usage with video and music files, but no problems so far.

I ordered 2 4GB cards from the UK-based Mobymemory (www.mobymemory.com) for UKP 79.98 (incl. tax and sqhipping to mainland Europe). They arrived this morning, are already in my NaB00 and virtual memory has been set on the internal card (it takes a very long time though). They work.

Many thanks to Internet Tablet forum poster "Flareup", who signaled them here:

Wait a minute: Does this mean with 2 cards this grows into an 8GB media player? This is really incredible, greast news. Thank you for doing the testing!

I've had two Transcend 4GB SD cards (non-HC) in my N800 for over a week, working fine.

The only issue is inefficient storage for very small files (e.g., downloaded maps for Maemo Mapper) due to the 32K cluster size as shipped.

I dedicated one card to maps, reformatted to 1K clusters (minimum for a 4GB FAT32 partition), and improved storage density by 17X for a large dataset: 87,376 files (total 90.9 MB) occupied 2732MB originally but shrank to 158MB after reformatting.

Because the smaller clusters do not match the internal block size, write speed is reduced, but read speed is barely affected (if at all). The default format is more appropriate for general usage.

And 8gb sd card?
Anyone have tested it?

While 4GB cards exist in both SD and SDHC flavors, 8GB and above (future, up to 32GB) must be SDHC, which is not yet supported by released versions of Nokia's OS 2007 kernel.

This explains why 4GB SD cards currently work in an unpatched N800, and 4GB/8GB SDHC cards do not.

Early user efforts at porting Linux SDHC support to the N800 have been mixed. Interested parties can follow developments on the Internet Tablet Talk forums: www.internettablettalk.com

Gah, and here I just bought a pair of 2GB cards yesterday because I was thinking all 4GB cards were SDHC...oh well.

I'm using a Patriot 4GB SD card in my external slot (the easier to share it with my digital camera). It works fine.

Allocating the virtual memory was very slow, on both the internal and external slots, with both the Patriot 4GB SD card and the card supplied with the N800.

This stuff is very confusing for the reagular user who does not even understand "flashing" let alone kernels. I bought a 4 gig minisd card thinking it would work. Now they are worthless to me because I need a simple(read real simple way to make them work.) It is very frustrating for someone who stumbles into all this linux stuff.
