My N800 was working fine with a 2 gig sd card until I downloaded the latest software update. Then, in a few days, the Navigation system card in the died in the middle of a trip to North Carolina. I bought a transend 8 gig card and that died a day ago (after 1 day). I had copied files from my pc to the Nokia with the card in the repalceable slot. It worked fine for a day then died. Now it doesn't even see that there is a card there.

Not sure what to do. Don't want to spend another $90 on a crad until there is some sort of path forward on this.

Any clues whethere it is the hardware itself (the N800) or the software that is messed up?

Not a power user, so I won't be fiddling with kernels (whatever they are) just a clueless end user

Jeep99,
You have more patience then me. After losing a single 2G SD card and reading of the experiences you and others have had, I've lost my love for the N800.

By chance, do you have a Mac and a card reader you can use? I use Windows, Linux, and Mac OSX....I find that it's often easy to bring cards back from the dead with Disk Utility on a Mac or QTParted on Linux....(I use Ubuntu). You may also have a faulty card slot....is it the same slot each time or does it happen in both? Could it be the laptop or card reader if you're using one to load data?
Maemo mapper temporarily messed up 3 different 4GB 150X Transcend SD Cards but I recovered them all by formatting them in a SD reader through COMMAND PROMPT (MS DOS) in WinXP... in the end I finally managed to get it to work without corrupting with all the maps I wanted on it.

Could it be that the tons of small files that Maemo Mapper uses for its maps is contributing or causing this issue? I know that the cards are rated for a certain amount of writes usually... but with a ton of small files, you're doing a ton of writes... I don't know.

It's going to be interesting to see if the issue suddenly disappears and stops being reported once the new version of Maemo Mapper is released with the new database file format.

(I love Maemo Mapper and i'm not trying to blame it for damage... just seems like a common thread.)

Maemo Mapper it the best program ever made for the Nokia N800... but sure it's the 2-3 million tiny files I put on the 4GB SD card that corrupted it.... 3X... it was soooooooooooooo frustrating starting all over again... many other people on here reported the same problem... but Maemo Mapper is so great I never stopped trying and now it't the only program I installed omn my Nokia N800 since the upgrade. (although I don't need to use to for practical reason much it still is their JUST IN CASE and I love the security of being the guy who always knows his way around).

It has been a trying experience. I haven't installed maemo mapper yet and from how it sounds, I probably won't be for some time if ever. I don't get lost much anyhow. I honestly think that opera on the tablet is my favorite. It's definately the most used.

I have been using MaemoMapper and it will break my SD card filesystem sometimes. Mostly when I am downloading map images.
Cards are always formatted for Windows FAT filesystem and that will cause problems on Linux OS. N800 (and 770) do not have any tools to check card filesystems and repair it. So connecting card to Windows (or desktop Linux) and checking card there should fix it. But only way to fix broken card is to format it into FAT32 on PC.
I just upgraded my N800 firmware, let's see if it works any better. And if it does not work any better should I buy any bigger SD cards for N800? Then I would have more data to be destroyed.

Yes Opera is my most used (tied with media Player) but they COME with the system upgare so I did not include them in with BEST SOFTWARE for Nokia N800... Maemo Mapper is the best 3rd Party Software with Pidgin (for my MSN contacts) a close second. If you only load 1GB of files with Maemo Mapper you should be ok... I got greedy and did the Whole Wide World (Zoom 15-9) and mainly North Amercia (Zoom 15-5) and very detailed locally (Zoom 15-1) and it took up the whole 4GB (minus 200mb for swap and backup).

It took me a week but I downloaded ALL THE MAPS ahead of time so now it hopefully won't destroy my SD card cuz it doesn;t have to write to it anymore. This was about 4 months ago and no problems since.

I didn't install maemo mapper on my N800 and didn't copy small files to my SDHC cards... But one "big" 700MB iso corrupted three of mine 8GB cards!
I don't think that this problem is related to writing small files. Perhaps maemo mapper is one of these applications that use the SD/SDHC cards more often than other applications! think about it...

Also I couldn't notice a difference between writing files from wlan or usb to SD/SDHC card... in both cases my external slot makes more problems than the internal one. I hope that nokia will find the origin of this problems soon...
