defect sdhc card slot?
 

Hi,

i bought a transcend 8GB SDHC (Class 6) several weeks ago and
used it in the internal card slot of my N800. Today my second transcend
card (same model) arrived and I put it in the external slot.

While downloading a 700MB iso (with wget) from my local ftp
for testing purposes, I got an input/output error. After that I couldn't
access the card anymore. Rebooting the device didn't help... the card isn't
recognised anymore! My HAMA sdhc card reader also doesn't recognise this card anymore.
After testing the other card with the same procedure in the external slot, I got
the same input/output error and this card is also defect now!
I have tested three transcend sdhc cards until now ... and all three gone bad
in the external slot... damn
My 1GB Navicore sd card works without problems in the external slot.

Could it be that the external slot is defective? How could that be...
I would understand if an input/output error would result in a defect partition
or somthing similar ... but corrupting the whole card?!

Did someone else had similar problems with sdhc cards???
Should I send my N800 to nokia for repair? (I don't want to do this...
I read to much bad info about nokia repairs ;))

EDIT:
I used the first card with the old 3.2007 firmware and sdhc kernel...
Tests with external slot were done with the new 4.2007 firmware.

Hi,
I've had similar problems with 2GB SD cards on the external slot. My N800 has corrupted 3 SD cards so far...

This might be related to downloading / saving a "big" file to the SD card. First time I was downloading a podcast (~40MB) from the net and the last time I was creating a backup (~45MB) before firmware update.

These cards are Sandisk micro SD cards and working really well on mobile phone, pocket pc device and Digital camera. I did have a bunch of these in use on various devices, but now N800 has eaten all my spare ones.

Re: defect sdhc card slot?
 

Were you able to "repair" your cards with your pc? Or are they completely damaged like mine?

Re: defect sdhc card slot?
 

If you haven't already done so, please post your experience to Bugzilla and vote for it:
https://bugs.maemo.org/show_bug.cgi?id=1204

It seem like this new firmware really messed up this issue big time! :mad:

Re: defect sdhc card slot?
 

So far I haven't been able to recover them.

Re: defect sdhc card slot?
 

I have already posted my experience and voted for this bug! But this doesn't
repair my sdhc cards :(

The main questions is: should I buy another sdhc card or should I send my N800 for repair??? Is this really a software only problem?

Re: defect sdhc card slot?
 

Did you try "Panasonic sdformatter"? This could be your last hope.
I weren't able to reformat my damaged sdhc cards :(

Re: defect sdhc card slot?
 

Understand... I have also destroyed one 2GB SD card completely. Another 4GB one is also not usable any more. (It still works but corrupts very quickly when copying data to it, especially large files.) This is the third 8GB card I have that corrupted yesterday with the new firmware! I still can read it but can not run windows disk check utility with it. (I don't have external SDHC card reader to try with that.) The only hope is trying to reformat it now.

I also suspect that this seem more like hardware issue. For your reference my tablet is Made in Korea and its WiFi number (serial) is 00194FD4E28B. Maybe we can track this down to some certain batch and could negotiate Nokia to send us all replacement tablet?

Re: defect sdhc card slot?
 

My tablet is made in Finland. Serial 00194F9E950C.
An official statement from nokia would be nice. But I don't think that
they will give us much info about this problem. We never received an
official statement to the touchscreen issue.

Another problem is that we could not ask other people to voluntarily kill their
sd cards ;) And I am not sure if I should risc another try with another sdhc card.

Re: defect sdhc card slot?
 

I think is time for Nokia to come out of the woods and admit this new firmware was a disaster waiting to happen! we are a bunch of guinea pigs for them. It is obvious... There is way to many problems with this new firmware for them not to know at least the basic problems they where going to encounter.

Re: defect sdhc card slot?
 

The external slot has corrupted my regular SD 2GB sandisk card. I have a transcend 4GB regular SD in the internal slot and am waiting delivery of a transcend 8GB SDHC card.

Question: Should I risk any card in the external slot ?

Re: defect sdhc card slot?
 

Is your SD card completely damaged or is only the filesystem corrupted?
If you have less problems with your internal slot, I would use this slot for the new SDHC ;)
Until now only my SDHC cards were damaged in the external slot ... My old
SD cards are still alive.
No risk, no fun :D

Re: defect sdhc card slot?
 

I think the best option is to wait until we hear back from Nokia - probably via bug #1204 - and hopefully within the next few days when they get back in the office.

Unfortunately Nokia made the mistake of staying silent about the touchscreen sensitivity issues leading many of us to go through the unecessary pain of repair when a software solution was available. With luck Nokia won't make that mistake again and will come clean about the SDHC card killing problem.

What I'm wondering is this - does Nokia they have a responsibility to replace all our dead cards if they cannot be revived?

Re: defect sdhc card slot?
 

Yes, but Panasonic formatter doesn't seem to help either.

At least in my case this is not related to the latest firmware only since I've managed to corrupt my SD's with the latest two firmware's (the only two I've used).
This has happened to cards on the external slot, so far no problems with the internal slot.

Re: defect sdhc card slot?
 

My problems started with N800 firmware 2.2007. But the SD cards were never dead. "Just" the filesystem was corrupted. But I had no luck with the SDHC cards. I had the hope that official SDHC support would solve my problems, but that was just a dream of mine.

Perhaps your dealer will exchange the defect card. I don't think that Nokia
will pay for our cards.

Re: defect sdhc card slot?
 

I have only used the internal slot and experienced this problem several times...

Re: defect sdhc card slot?
 

My problem started with the card being seen by the n800 as read only.
Rebooting / reseating sometimes cleared that. I also reformatted the
card. Eventually the card stopped working, wouldn't read, can't reformat.

I cannot reformat on XP, I can reformat on n800, except it doesn't do it
correctly. On XP, the newly formatted card says it holds 1.5gb, but is
empty. Yup, the card is well done for.
