What does RTT mean? (apart from the telecommunications meaning)

And to signify that a byte is eight bits, the French decided -pretentioulsy, as usual- to rename it "octet". So a "Go" is a Gigaoctet.

Oh ok. Didn't see the first time you posted that.

Anyway, I'm still wondering why it doesn't say Startup Disk.

I think RTT probably means "read the thread".
