Here are calculations:
Your drive is 80G by manufacturer's definition so it is 80x10e9 =80000000000
The real 80G would be 80xe30 = 85899345920
so your drive is roughly 6Gb less than if should be thanks to the way manufacturer counts. So the real size of the drive in normal numbers is 74G.
Now take 7% off, 74x0.93=68G that is less or more is what you have got.
The numbers are not exact because different hard drives have different physical parameters, as different number of surfaces, different ways to organize data (horizontal, vertical and so on).
You can do it with any hard drive to get the real size estimations.

Hi,
Is their an easy way to realloate hard drive space on Solaris 10.
For example :

I would like to move some of the hard-drive space from "/space" and add it to "/c20td0". In Windows this can be easily done using Partition magic, anything similar for UNIX? (4 Replies)

CAL(1) User Commands CAL(1)
NAME
cal - display a calendar
SYNOPSIS
cal [options] [[[day] month] year]
DESCRIPTION
cal displays a simple calendar. If no arguments are specified, the current month is displayed.
OPTIONS
-1, --one
Display single month output. (This is the default.)
-3, --three
Display prev/current/next month output.
-s, --sunday
Display Sunday as the first day of the week.
-m, --monday
Display Monday as the first day of the week.
-j, --julian
Display Julian dates (days one-based, numbered from January 1).
-y, --year
Display a calendar for the current year.
-V, --version
Display version information and exit.
-h, --help
Display help screen and exit.
PARAMETERS
A single parameter specifies the year (1 - 9999) to be displayed; note the year must be fully specified: cal 89 will not display a calendar
for 1989.
Two parameters denote the month (1 - 12) and year.
Three parameters denote the day (1-31), month and year, and the day will be highlighted if the calendar is displayed on a terminal. If no
parameters are specified, the current month's calendar is displayed.
A year starts on Jan 1. The first day of the week is determined by the locale.
The Gregorian Reformation is assumed to have occurred in 1752 on the 3rd of September. By this time, most countries had recognized the ref-
ormation (although a few did not recognize it until the early 1900's). Ten days following that date were eliminated by the reformation, so
the calendar for that month is a bit unusual.
HISTORY
A cal command appeared in Version 6 AT&T UNIX.
AVAILABILITY
The cal command is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/.
