When I try to copy files from my computer running in windows 8 to a sdcard, or usb flash bigger than 8 G, the files become corrupted, not all time, not every one, but more than the half become corrupted.
I tried to check and repair (with or without corrupted files on the flash/sdcard), to format again with fat32, ntfs and exfat, scandisk for errors, copy back the files to the original position, copy to another folder in the computer or in the flash/sdcard and nothing solve the problem.
I tried in 3 different computers running windows 8 (1 laptop, 1 desktop) and 7 (1 laptop) and I tried with different microsdcard and usb flash. 3 of 8G, 2 of 32 G and 2 of 256 G form different branch, and the problem persist
There is some body with this problem and solution (this is the most important thing)
thanks

Not questioning what you say, but am wondering HOW you determined that the files saved to SDCards or USB sticks were corrupted? Did you try reading them in another PC? If so, what OS is the other PC running?

I am just reading what the text box say, that's why i said they become corrupted and yes, I tried to read them in another computer, like I said in my original writing, I tried in 3 different computers, 2 laptops and 1 desktop, running windows 7 and 8, but not other SO or computers, the thing is when I do the same operation with a flash or micro with less than 8 G, everything goes good, and I can read and play and whatever on 3 computers and on all external devices, the problem begin when I try to do the same with external devices more than 8G

Sounds like a nasty problem . can you find a "memory dump" utility to display the data ? Then you could see if particular bits in the data words were being mutilated or whether the beginning or end of the transfered files had become corrupt - Just a few ideas here - good luck.

Thank you, I decide to buy external hdd, it works, I don't want to deal anymore with this problem, I am almost sure that something is going wrong with windows 7 and 8 with large external usb or sdcard, because I tried on windows xp and vista and I don't have this problem, the only problem is that I have windows 8 installed,
One more time, thank you, maybe microsoft engineers in the next windows figure out the problem
