Re: SDHC Corruption bug back?
 
It is happening to me even with normal SD card (internal) 2GB and running OS2007. It looks to me like memory card gets locked. May be because of lose contacts of back cover. So what I do is just open the back cover a bit and close it, then I get a message "i Memory card available". Then all works fine :(

I've been using Linux as my primary OS for about 8 years now, but when I use the tablet I try to use it fairly stock. I don't use becomeroot, and I won't do things that a 'normal' consumer won't.

Still, this is fairly disturbing as it's the first major data loss I've had on the N800. I had never run into the older SDHC bug, but now I'm slightly nervous.

I'd be very careful doing that... if you do that in the middle of a write operation you'll end up losing data.

The availability of memory cards depends on the magnet you have on the cover internal part. Be sure it is not moved or disconnected or whatever

How we will know when the back cover is moved? An icon indicating "Internal memory card not available" could be interesting!

The card killer is back again?...NOOOO. I get a fried 2gb SD with previous version of OS2007.

Gah, add me to the list.

I'm getting troubles with my 2GB Crucial SD card in the internal slot under the back cover. I used a card reader last night to put some MP3s on the card and this morning everything was garbled. I formatted the card and now it's acting "read only" again (similar to the old OS2007 problem). It's the most irritating problem because you can't ever use the device for long without having to wipe everything down and start all over.

Sloan, you probably pulled the card or USB cable out before your mp3s were finished transferring. Don't believe your OS when it says that the transfer is finished because it's usually NOT. On Linux, if you mount your card sync, it will make sure that you won't have this problem, but the transfer will appear to go slower. With async (the default), it will appear that the transfer is finished. In reality, it's just been done flushing the write to the card reader, which takes additional time to write to the card.

A good rule of thumb is to just wait an extra minute or two after the transfer appears to be complete on your computer before pulling out the cable or card. If it's a very large transfer (1GB+), give it an extra minute or so. You should have a lot less trouble then. (Since instituting this rule on myself, I haven't had a single card issue in 8 months.)

(This is not a Nokia or tablet problem. This is a flaw in the way card readers work. Nothing can be done about it.)

How about waiting until the little light stops flashing?

That will work too, but many card readers just don't have lights anymore.

Has anyone figured out how to fix this problem?

I am using a Transcend 2gb SD card (not sdhc). It's not very old. Since installing the OS2008 beta, while listening to music (in various players) the music would stop all of a sudden and the files would disappear from the card. This could be solve by rebooting, but would eventually happen again.

I reinstalled OS2007 but the problem remained, so I moved all the files from the card to my computer, formatted the card, and moved the files back onto it. Same problem.

Is this similar to what others have experienced? Is the card toast, or can it be salvaged somehow?
