Yes, that's why I included both the G value and G. More precisely 29260513280 bytes, which is the 57149440 sectors. It hasn't exhibited any failures, but considering its price I'm going to try to RMA it. They even have a 30GB product and I would still claim false advertising if I got 29.26GB. Daniel
This was litigated more than a decade ago. See http://www.foxnews.com/story/2006/06/28/western-digital-settles-hard-drive-capacity-lawsuit.html and others. Specifically from the article
"Western Digital Corp. is offering free software to about 1 million consumers to resolve a class-action lawsuit alleging that its computer hard drives stored less material than promised — a discrepancy stemming from the high-tech industry's differing standards for sizing up digital data."
I am not singling out WD for this, rather this is a very well known and well understood unit conversion problem, as well as a formatted capacity issue. Here is an entry from their FAQ: https://support.wdc.com/knowledgebase/answer.aspx?ID=615
Pretty much all drives sold over last 10+ years include a disclaimer such as this (from an HGST data sheet)
"One megabyte (MB) is equal to one million bytes, one gigabyte (GB) is equal to 1,000MB (one billion bytes), and one terabyte (TB) is equal to 1,000GB (one trillion bytes) when referring to storage capacity. Accessible capacity will vary from the stated capacity due to formatting, system software, and other factors"
