Why is it that I can't access a few files on my HD? There are a few video files, executables and archives like this. I have downloaded them just like any other file, but I can't do anything with them, not open, move, rename, copy, change attributes etc. The only thing I can do is look at the files' properties. Windows (XP Pro SP2) just basically gives the error "Access is denied", depending on the operation I'm trying. Could it be some malfunction with the drive (an external Lacie 160 GB)? I've done a CHKDSK on it (with a boot), but it made no difference. The drive has also been defragmented multiple times. And I've applied some registry fixes that are supposed to help access big AVI files. Could it be a virus? Data execution prevention? I'm a bit out of ideas. Thanks for reading.
