The 160Gb figure is the drive's raw unformatted value, which of course works out to be 160Gb.

Once you format the drive and take in overheads and round the figures off properly, a 160Gb drive only comes up as c. 155Gb.

What normally happens is the manufacturer sells it as having 160,000 Megabytes where 1000 Megabytes = 1 Gigabyte.
In reality, a gigabyte is 1024 Megabytes, so 160,000 divided by 1024 = 156.25 Gb. Figures vary from drive to drive, manufacturer to manufacturer.

In the case of branded computers like HP, take another six or so gigabytes out for their built-in system recovery partition software.
