I had a working 2gb miniSD card in my external slot.

I got a 8gb microSD card for xmas (yay!), and so pulled the 2gb card, and put the 8gb card into the nifty new Sandisk microSD->miniSD adapter.

Which, of course, didn't work. Wasn't recognized as being present or anything. THEN I found mention of that particular brand of adapter being crap...

So I put the 2gb miniSD card back in and... get the dreaded "memory card is incorrectly formatted or corrupted" error. Yikes!

Only -- if I plug the n810 into USB, I can see the card just fine from my computer, contents and all. So clearly it's NOT gone south on me.

I've tried rebooting a few times, but no dice. Should I be looking at partition table info somewhere on the n810 itself, or what? Help!

The N810 might just be more picky when it comes to filesystem errors than Windows XP.

Try running a full filesystem check and repair, either on the N810 (with the fsck.vfat utility) or from your Windows machine.

Using the scan-and-repair thingy in WinXP produced no errors.

I can get the miniSD adapter to throw the exact same error now (which is a step up from being agnostic about its very existance before). But really, at this point I'd settle for getting the 2gb miniSD card to work as it was before.

You can try either backing up the card to your computer, formatting the card, and copy files back, or as root "fsck.vfat /dev/mmcblk1p1" on the device itself.

Edit: And the -a option in fsck will automatically repair problems. (though it never works for me...)

I'm about to the reformat-and-try-again stage, but first:

I did the fsck.vfat line, and got:

open /dev/mmcblk1p1: No such file or directory

A cat of /proc/partitions shows the following (ignoring the entries for mtdblock[0-4]):

254 8 1966080 mmcblk1
254 9 1966072 mmcblk1p1
254 0 1966080 mmcblk0

In /dev/ I have /dev/mmcblk0, /dev/mmcblk0p1, and /dev/mmcblk1, but not blk1p1.

Format time?

-Jennifer

Huh? /dev and /proc/partitions don't agree on which card has partitions? Or is it just a typo in your post?

Not a typo! I just doublechecked -- that is exactly what my device is reporting. The 'internal' card/filesystem works just fine.

I have since reformated the card (FAT32, via Windows, because File Manager on the n810 only managed to mark it as unformatted according to WinXP... I didn't try telling it to format it again), and am currently copying my files back onto it.

I plan to reboot it at least once if not a few times once I get the files all copied back, and see if it recognizes it again. I'll let you know how it goes...

-Jennifer

FINALLY success!

After unplugging the USB, it still complained that the card was corrupted. After reboot, it correctly sees it now.

I got a hunch, and turned it off entirely before swapping out the 2gb card for the newer 8gb card-w-adapter. (I swear I've done 'hot' swaps in the past with no problem...) The newer card is now also seen and correctly recognized.

And /proc/partitions and /dev/mmc* match up nicely once again.

if you have a digital camera try poppin the card in there and if there's an error cameras (especially panasonic it seems) are pretty good at formatting / repairing. make sure u backup your files though
