CopyPaist From Cf to Pc

I reformated my Cf card tonight. I started by backing up to my Pc first then reformated and when I tried to copy the folders back to the card it corrupted 2 of them , the 2 were fine upon copying to the Pc but when i try and copy back to the card I get an error message. Now the weird thing is I tried and reformated again and recopied the data back and this time only 1 was corrupt....what gives ? I hope someone figures out how to uncorrupt a file ...I have about 5 so far..all full songs too. Damn

Thanks but this is NOT the WRONG FILE ERROR....this is Corrupt File error...anyone else?

Are you actually highlighting the files then, hitting copy and paste? Try dragging them....

if u copy them to your pc and the then copy them to ur cf there is something interfering. Do u load the cf into a cardreader in your pc? or do u send them thru the usb to the mpc? Corrupting happens most of the time cos of bad ram or a bad cf. maybe the usb cable is not intact. try to load copy it thru a cardreader conencted to the pc, maybe that helps. And u're sure u are virusfree??

I'm using a card reader and copy to folder commands... I'll try the drag and drop method but I dont think that could be the issue. I'm definately Virus Free my music machine has never been connected to the internet and all files get opened on my internet machine and scanned before going to the mothership.
