Toorcon Hard Drive Data Recovery


Eliot and I caught Scott Moulton’s talk on Hacking Hard Drives for Data Recovery. You can catch his slides here – but most of the content was in the talk. It was a great walk through of hard drive technology. Some interesting points: 85% of the time, software recovery is successful. 10% of the time, replacing the controller board succeeds. So, 95% of the time you can probably recover your data fairly easily.

Scott showed off a peltier enhanced drive sled for keeping a drive cooled for optimal operation/recovery conditions. He even got into replacing drive heads. If you’ve ever gutted a drive, you’ll know how fragile those heads are. You can actually fold a postit note to keep the heads apart and tranfer an arm with heads from a donor drive to get your drive working again. The difficulty of the operations seem to increase exponentially as the number of platters increases.

Linux On Obsolete Displays

[bryan chafy] has been hacking away to get older non VGA displays running on VGA hardware without using a scan converter. You can pick these old grayscales up for cheap or even free. The tricky part is modifying the BIOS to reprogram the VGA card to output a sync and scanrate that is NTSC compliant. He’s managed to do this with a WYSE Winterm thin-client. Another clever trick is the poor man’s triple head display which stores a different image in each portion of the RGB signal.

Hard Drive Oscilloscope

[hackgadgets.com is back up… maybe]

[Alan] put together a list of the Top 5 Dead Hard Drive Projects. He suggested we post about the hard drive laser oscilloscope, since he couldn’t find the project anywhere else. I actually saw a similar project during dorkbot-sf‘s presentation at Maker Faire. A laser is mounted to the drive case. The beam is bounced off of a mirror connected to the read/write head. He’s got a video of it in action on his site. Have a look at the other hard drive projects as well.
