Before someone tell you to "Search" I'll post the poorly documented /media/mmc1 corruption bug.

Learned how to recursive download to media memory card (MMC).
Copied downloaded html files from flash to memory card to make room on flash.
And finally tried to remove wget downloaded files from media memory card
and found out any, every, each file to be asterisked and can not be deleted.
run mount from command line
one entry for /media/mmc1
/dev/mcblk0.. on /media/mmc1 type vfat (rw, noauto, nodev, noexec, nosuid, utf8, uid=29999, shortname=mixed, dmask=000)
chmod -x /media/mmc1
chmod: /media/mmc1: Read-only file system
I get used media card to save maps in maemo mapper,
today no chance to run maemo-mapper.
Please tell me how to have /media/mmc1 back read-write file system,
as did nothing exceptionally to change status of media file system.

a corrupted card or, better, a corrupted swap file. Go control panel>Memory>Virtual> uncheck Extend virtual memory. See that will solve the problem. Post back results.

Actually, that won't fix it. Here's what I ended up finding out works.
1. Shut down your unit. Totally power it off.
2. Plug in the USB to the device, and your PC.
3. Boot the device.
4. Watch for it to automount on your PC. When it does, ensure that you're viewing the contents of MMC1.
5. Scandisk/fsck the drive.
*If you're on Windows, you may need to close the explorer window, or navigate away from the drive before doing that so that Windows doesn't toss a fit about the drive being in use when you go to scandisk it.
*If you're on Linux/BSD, be sure to unmount the disk first before doing fsck. That allows for a much deeper scan and correction of the disk. It can still be fsck'ed while mounted, but a deep scan won't be possible.
6. Once this is done, unplug the USB.
7. Now check the state of the disk. If it's still read only, repeat these steps. If not, you should be good to go from there.
Hope this helps.

[QUOTE=Lord Raiden;212967]Actually, that won't fix it...
Excuxe me?
I think you meant to say "If that won't fix it.....". That is how I fixed mine. Unchecked the swap file and recheck, that fixed the corruption and problem solved.
Thanks for the info though.

I thought repartitioning is the only way to fix the N810's habit of corrupting the internal memory "card", since the corruption is due to incorrect partitioning from the factory.

Ace: Nope, it's caused by a write bug of some sort that deals with the swap file.
bunanson: I tried that originally on mine and it didn't work. Hence why I said what I did. Also, on mine the corrupted file was not the swap, but a map file.

Finally, if all this littel tricks failed, I would have to do thru what your post suggested. The point is, there are many ways to clean up problems, always go with the small steps first, if it works.

Ok, yeah, that's cool. My issue just turned out to be something other than the swap file.
