It looks better on the box. It gets messy with drive advertisements as there's no required standard for how they advertise a gigabyte, and whether it's formatted or unformatted capacity. I just assume they're advertising unformatted capacity with 1,000,000,000 bytes as a gig, then I'm pleasantly surprised in the end if I have more than I expected. :) Cheers, Brent -----Original Message----- From: owner-freebsd-questions@freebsd.org [mailto:owner-freebsd-questions@freebsd.org] On Behalf Of jekillen Sent: Thursday, 20 September 2007 12:47 p.m. To: FreeBSD Mailing List Subject: Hard drive RPM Hello; I have one that was expressly advertised on the package to be 120 Gb capacity, and in fact only 111Gb are available for storage. That is a 9 Gb discrepancy. A Fire wire drive I have is also designated as 120 Gb and actually only has 117 Gb usable capacity. Like 9Gb is enough for several operating systems. 3Gb is even enough for an operating system. Can anyone shed some light on this? (Storage device labeling, and specifically, RPM specs) I would ask the manufacturers but would be suspicious of bias responses. That is what I got from one of them already. Thanks in advance for responses. The hard drives in question are running on FreeBSD systems on homebuilt hardware. All AMD64 processors, ECS, Gigabyte, and ASUS motherboards, Hard drives are Western Digital IDE, SATA, and Seagate SCSI drives.
