Error 36 Mac transport file or copying
Try dragging the folder to the desktop, highlight it, in the Finder window drop file menu click get info and se if locked is checked, if so unlock it.
Also I would do a complete back up in case you do have a drive on the way out.
There could be something corrupt as well.
Try a permissions repair: Go>utilities>disk utilities, highlight your user drive (usually Mac HD or what you may have named it), clickRepair Permissions, tis can take a while
Maybe you'll find some help here.
