What is the purpose of the holes marked "Do Not Cover" on hard drives?

  • Speaking of Blog I still want to know why they dont go with a (partial) Vaccume in the drive, it would reduce friction, reduce oxidation, and moisture entry. The only thing I could come up with , it still needs the Air movement, the "wind" because particles that come off of the head and platters, gets splattered into another filter?? I cannot see where it would be a problem with "altitude", decompressed cargo accidents, heat, expansion/contraction or any reason why they dont?

Why don't you see binary code when you open a binary file with text editor?

Why you don't see binary code when you open binary file with text editor? For example when I open image with text editor I see some weird characters and also some human readable characters. But image should be encoded in binary.
