Re: what to do after update.?
 

No problem here, the new firmware has worked fine, what is killing the card? Wrong voltage or what?

Re: what to do after update.?
 

We don't have an official statement from nokia. My SDHC cards were killed while
transferring large files over wlan. Perhaps the N800 itself is defect.
Sending it for repair is a huge risk. Some people with touchscreen issues (for example)
had to wait several weeks until they got a response from nokia
... and we don't know if its really a hardware problem. Perhaps a soon (?)
firmware update will correct this problem.

Re: what to do after update.?
 

Its possible ...

Palm have made a bug in the first release of the Tungsten E where the card can be killed. And it s patched with a software update.

Good to know... Thank you for that info!
So we can hope that this is also "just" a software problem.

I think N770-Freak has provided you with sufficient proof (not that any were necessary) however even if his situation is just a coincidence (along with the others also with dead cards) there is no harm being cautious until Nokia provide clarification.

Re: what to do after update.?
 

N770-Freak - have you attempted to re-partition one of your "dead" cards with sfdisk on the N800 itself, or Ubuntu?

Re: what to do after update.?
 

yes... that was the first thing I tried. But the card itself isn't even recognized.
dmesg in N800 just says (short form): cover is closed, setting voltage 3300 mV ... 2800 mV ... 0 mV
and there is no device created in /dev !
No chance to reformat or repartition such a card that doesn't exist in the OS.

Same with ubuntu... cardreader was recognized, sdhc card not.
Like there were no card in the reader. Absolutely dead.

If you or someone else has further ideas how I should test this card, please write down a post. It cannot become more badly :D

Re: what to do after update.?
 

the same thing happened to me with 1gb micro sd. the n800 wouldn't even see it! so i stuck it i my wifes e61i, and was able to reformat.. its been fine ever since. (knock on wood)
i havent updated yet, but was planning on it today. should i hold off until further notice?

Re: what to do after update.?
 

Most people that have problems with sd/sdhc card had this problems already before 4.2007... so I would not say that you should not try an update.
Did your problem with the sd card only appear in one of the two slots of your N800 or
did you have this problem only once?

Re: what to do after update.?
 

Sadly I don't have any other suggestions, but the above dmesg information would be useful detail in bug #1204 which may provide some clues to Nokia...
