Bypassing Seagate ATA Security Lock


Here’s a common story when it comes to password retrieval: guy sets up a PC, and being very security-conscious, puts a password on his Seagate hard drive. Fast forward a few months, and the password is, of course, forgotten. Hard drive gets shuffled around between a few ‘computer experts’ in an attempt to solve the problem, and eventually winds up on [blacklotus89]‘s workbench. Here’s how he solved this problem.

What followed is a walk down Hackaday posts from years ago. [blacklotus] originally found one of our posts regarding the ATA password lock on a hard drive. After downloading the required tool, he found it only worked on WD hard drives, and not the Seagate sitting lifeless on his desk. Another Hackaday post proved to be more promising. By accessing the hard drive controller’s serial port, [blacklotus] was able to see the first few lines of the memory and the buffer.

Two hours and two Python scripts later, [blacklotus] was able to dump the contents of his drive. He then took another Seagate drive, locked it, dumped it, and analyzed the data coming from this new locked drive. He found his old password and used the same method to look for the password on the old, previously impenetrable drive. It turns out the password for the old drive was set to ‘0000’, an apparently highly secure password.

In going through a few forums, [blacklotus] found a lot of people asking for help with the same problem, and a lot of replies saying. ‘we don’t know if this hard drive is yours so we can’t help you.’ It appears those code junkies didn’t know how to unlock a hard drive ether, so [blacklotus] put all his tools up on GitHub. Great work, and something that didn’t end up as a Hackaday Fail of the Week as [blacklotus] originally expected.

Free home phone method uses parts we’re familiar with

[Headsheez] found a way to get his home phone service for free. He’s using a set of tools that we’re familiar with to route service from a typical analog phone system (which involves the extensions wired into your home) through a server to the Internet. On the hardware side of things this starts out with an Analog Telephone Adapter which translates the analog signal for use in a PBX system. He uses a copy of the open source PBX project called Asterisk which we’ve also seen used on devices like routers and the SheevaPlug. The actual telephone number comes from a Google voice account which for now is a free service but there’s no guarantee that it will remain that way in the future.

This should provide seamless service just like you’re used to with a traditional home phone line. There’s even caller ID for the number – but not the name – for incoming calls. The one big feature that is missing from this setup is the ability to call 911 for emergencies.
