Inversely, that's 0.000625% "wasted", worth roughly 1/5 of 1 penny US, or $0.0002. Your time spent thinking about it - $25. Also, 10,000 sysadmins on this list X 2 minutes = 3333 hours X $100/hour = $333,333. I'd burn the 1MB and move on. -- Ray Morris support@bettercgi.com Strongbox - The next generation in site security: http://www.bettercgi.com/strongbox/ Throttlebox - Intelligent Bandwidth Control http://www.bettercgi.com/throttlebox/ Strongbox / Throttlebox affiliate program: http://www.bettercgi.com/affiliates/user/register.php On 03/19/2010 01:54:52 PM, Phillip Susi wrote: > On 3/19/2010 2:36 PM, Eugene Vilensky wrote: > > Align the partition? > > Then I waste 512k on the MBR, and another 512k on the pv header.
