I was thinking to use my knoppix cd to repare (if so needs) my computer, First time I installed win xpp did a system file crash and I had to erase the hole partation. So I dont want to have to do that again on my win partion, so I was thinking if I could replace the files that would be broken so i tryed to copy som audio files from my usb drive ( a data-bar 128mb ) to my win xpp partation but it didnt work?! I have tried to change the read only to read and write but no luck. Could it be cause my partation is NFTS? I can copy files from my C: partation to the usb drive.
