Hiding files on an External Harddrive

Hi. I have a 2.5'' 60GB external hard drive, and when i connect it to my Macbook, it opens and theres 3 folders that are to do with the hard drive, like recycle, system information and another i forgot the name of.

Can i delete these as its anoyying when they're there. Or is there a way to hide them, as Windows automatically hides folders like these.

Thanks

Open up the Teminal app.

cd /Volumes/name_of_ext_hd

touch .hidden <enter>

pico .hidden <enter>

<type the case sensitive names of the files you want to hide. One on each line.>
-example

Recycle
System Information

Now save the file

ctrl+o <enter>

ctrl+x

Then relaunch the Finder

Files will now be hidden to Mac only
