Can't unmount mmc card, device busy

[schmolch]

I just rebooted and still get a device busy error trying to umount /media/mmc1.
The osso-mmc-umount script gives the same error.

WTF could be wrong, i need to run fsck cause i get tons of i/o errors on the card.

No swap file ?

proparly you have swap enabled.....

After some time i was able to mount and reformat it on my laptop but i still get I/O errors so the card is probably already dead.
If so, i will certainly never ever buy something from .hk again.

Thats weird, i made a new ext2 filesystem 3 or 4 times and every time i get I/O Errors when i try to copy my files onto it, but now i made a vfat and got no errors :-/

dammit, now i cant create a swapfile anymore, even after formating (again).
im getting really tired of this sh*t now.

update: sorry for that, this was my fault, i had to chown the mmc before it could create the swap-file.
