I just realized something odd: I have a drive that is occasionally reported at the wrong size — it’s a 120Gb drive, one that fell out of the sky on me, years ago.
Sometimes operating systems, to include Linux, report it at only 40Gb. Arch does that, and so does Debian 6.
But not Debian 5. El cinco reports it at its full dimensions, and will partition it normally.
I wonder why that is.
