'''Lecture is CANCELLED !!''' We will plan a new date asap. Repeat of the talk given on [https://program.ohm2013.org/event/67.html OHM2013]. For more information of the talks [http://spritesmods.com/?art=hddhack on his site] or follow him on [https://twitter.com/SpritesMods twitter]. There is no fee, if you want to come please send me a [mailto:dave@tkkrlab.nl email] so i know how busy its get. From the lecture page [https://program.ohm2013.org/event/67.html OHM]: In this talk, we take a look at one of the more obscure parts of an hard disk: the HD controller. In any cheapo disk, it should do nothing more than channel bits between the SATA-port and the heads on the platter, but what does it actually consist of? And can we make it do some more interesting things? From an OS view, a hard disk is a very simplistic device: any block you write to it, you can read back later in it's exact same form. You'd almost think a hard disk doesn't do much more than dump the data on the SATA-port directly to it's magnetic surface, and will read it back in about the same way. A cursory look at the PCB of a hard disk will confirm this to the casual observer: there's a motor controller, some RAM and a chip connecting to it all. That last chip, the hard disk controller, is a mysterious thing. A Google search for most of the part numbers displayed on them will give you no datasheet, no specsheet, not even a mention on the website of the manufacturer. Nevertheless, you sometimes see firmware updates for hard disks, so these chips must have some kind of processor... A processor also implies something: hackability. In this talk, we'll take a look at a reverse-engineered internal view of these controllers. It's also possible to 'amend' the firmware they run with some routines of our own, and this talk will also demonstrate that.
