great! when you formated sd card, which file allocation system did you use? fat32, ntfs or some other?
NTFS. If you click the link in my previous post, you can see. Some of the defect cards i could directly
clean with diskpart, but some of them gave an error. These cards i first formatted with SD formatter,
and after that i could run diskpart without any error. I just formatted all the defect cards with succes.
Now installing the X10 file on the cards.
1 of the X10's is finally running perfectly now!

The others i will know in a few hours. Hope to have them all up
and running by then.
