the problem that i am having is that i'm trying to get some large files off my hard drive and on to disk to free up space. however whilst they will all write to disk, some will play from the disk and others will not. i dont think they would write in the first place if there wasn't space on the disk. so why will the file on the pc play but the exact same file that ive written to disk wont. can anyone help ? this is doing my head in.
