I have not done it....but just wondered what would happen if you were to scan disk/de-fragment your 6600 mmc card with windows when its plugged into a card reader?

It would defrag it like a normal disk.

But some people say there is no need to de-frag an MMC, personaly I found it made my phone appear a little faster and smoother in opening images and videos, but may have been my imagnation.
Some people say it reduces the life of the MMC as a defrag uses MANY read/write operations on the MMC.

But Personally, I found it to be fine and I've defragged mine a couple of times now and had my MMC for 18 months with no problems..

Best

U mean, we plugged it into MMC reader and defrag it just like we defrag HDD in PC ? :confused:

Yep - that's it. :)

Thanks. I might try it, see whether it will go faster then before. ;)
