[QUOTE="chscag, post: 1211069, member: 46727"] An external hard drive can be used to boot from provided it's formatted correctly and the operating system is installed. The external would have to be formatted as Mac OS Extended Journaled using the GUID partition scheme. Attach it via USB or FW and hold down the OPTION key during the boot cycle to choose the external as the boot device. A warning though... it will be slow. Also, what kind of hard drive are you referring to that costs $200? [URL="http://eshop.macsales.com/shop/hard-drives/2.5-Notebook/"]OWC[/URL] has large 7200 RPM hard drives of various manufacturers all for less than $100, some for $70 or $80. [/QUOTE]
