[1.33] copy fail

When i give the command copy or cp it says cp sourse destenation normal

but when i type cp hello disk
says he no such file

but when i type cp disk hello
then says it copy complete

disk isn't a file, disk is a directory, thus it won't work
To copy hello to a disk, you'd have to call

cp hello disk/hello

And not to sound rude, but try to use better spelling and grammar when asking questions, people are less likely to be put off by it.
