Hidden protected area

General information about the HPA FROM – URL: thinkwiki.org/wiki/Hidden_Protected_Area

As opposed to Recovery Partitions, Protected Service Areas (PSAs) such as the HPA are (let’s say) images of partitions written to the end of a harddisk. They are only accessible through their BEER. The general idea is that, under control of the BIOS, the PSAs are totally hidden from all ordinary software, including malware (viruses, trojans, spyware). They are only accessible when permitted by the BIOS, and even then only through special HPA-aware tools. Under GNU/Linux they are only accessible with low level tools like dd.

Combined with info at URL: http://en.wikipedia.org/wiki/Host_protected_area – and the HPcreate.png diagram – and I get some ideas of what is required when dealing with the R61-Service partition.
