Hard Drive Teardown

June 7, 2011 by Nick Schulze 6 Comments

Do you know how a modern hard drive works? If you don’t you should have a pretty good idea after watching this video. In only five minutes [Bill Hammack] manages to describe a hard drive in awesome detail without using any unnecessary scientific jargon.

The video teardown explains how the flying head “flies” how voice coil motors work and provides a basic introduction to how the binary data is stored and processed in the disk. The way the flying head maintains the miniscule distance from the plate is particularly clever. You may remember the LCD monitor teardown by the Engineer Guy, equally as detailed and interesting. The video after the break is definitely worth a watch.

Thrift Store Hard Drive Enclosure

May 2, 2011 by Kevin Dady 8 Comments

[Ken] visited our site looking for case modding stuff a little while back, but more importantly he came back to show off his latest project. Using a jewelry box found at our favorite place, the thrift store, he converted it into a 2.5 inch USB drive enclosure.

Almost instantly he found that this particular jewelry box is a perfect fit for a 2.5 inch SATA laptop drive. Taking that as a sign he whipped up some acrylic mounts and cut some holes for power and USB . The electronics are provided by another enclosure with a dead drive, again acrylic is used to insulate the drive from the decorative metal box and some rubber washers were used to help cancel out vibrations and noise.

The end result is a classy looking 150gig usb drive that looks nice on the desk, and a little reminder that if your not hitting up your local thrift / second hand stores, you could be missing out on some real gems.

HDD Unlocking On The Mitsubishi Multi-Communication System

April 29, 2011 by Mike Szczys 15 Comments

It’s a few years old, but [Brian360’s] method of unlocking the hard drive on his Mitsubishi Multi-Communication System is quite interesting. Mitsubishi describes their MMCS as a human-vehicle communication tool. It’s basically an in-dash screen and controls to display navigation maps and play music. [Brian] found that the hard drive for the MMCS in his 2008 Lancer was locked, and could not be cloned and swapped out for a larger drive. Sound familiar to anyone? Hard drive locking has been used in many systems, including the original Xbox, which we’ll get back to in a minute.

The setup seen above was used to grab the hard drive password from the system itself. A custom adapter card was built and plugged in between the hard drive and the MMCS hardware, with test points for each of the data line. [Brian] attached a digital storage oscilloscope, and after a bit of poking around, found a way to trigger the scope when the password was requested. He explains the process of converting the captured data into an ASCII string password.

With that in hand how would you unlock the drive? The favorite tool for this is hdparm, a tool which was used with early Xbox unlocking but which is still in use with other hardware today. Now brian has a disk image backup and the ability to swap out for larger hardware.

IDE Bus Sniffing And Hard Drive Password Recovery

April 28, 2011 by Mike Nathan 34 Comments

hdd_password_recovery

shackspace member [@dop3j0e] found himself in a real bind when trying to recover some data after his ThinkPad’s fingerprint scanner died. You see, he stored his hard drive password in the scanner, and over time completely forgot what it was. Once the scanner stopped working, he had no way to get at his data.

He brainstormed, trying to figure out the best way to recover his data. He considered reverse engineering the BIOS, which was an interesting exercise, but it did not yield any password data. He also thought about swapping the hard drive’s logic board with that of a similar drive, but it turns out that the password is stored on the platters, not the PCB.

With his options quickly running out, he turned to a piece of open-source hardware we’ve covered here in the past, the OpenBench Logic Sniffer. The IDE bus contains 16 data pins, and lucky for [@dop3j0e] the OpenBench has 16 5v pins as well – a perfect match. He wired the sniffer up to the laptop and booted the computer, watching SUMP for the unlock command to be issued. Sure enough he captured the password with ease, after which he unlocked and permanently removed it using hdparm.

Be sure to check out [@dop3j0e’s] presentation on the subject if you are interested in learning more about how the recovery was done.

90 TB Drive Array For Home Storage Needs

October 21, 2010 by Mike Szczys 53 Comments

Why store it in the cloud when you could have a 90 Terabyte hard drive (translated) array in your house? The drives are mostly Western Digital Caviar Green EARS 2TB models which are known for energy efficiency and quiet operation. It’s a little unclear as to whether this is using one or two motherboards, but the drives are connected using PCI RAID5 and RAID5+0 controller cards. There’s a total of 40 cooling fans built into the case, half on the bottom and the rest on the top. They move air up through the case, with plans to add a dust filter in the future. Heck, with that type of air movement you could throw on a standard furnace filter. Apparently it is quiet enough to talk in “almost a whisper” while next to the plywood monolith. But we’re a bit skeptical of that claim.

It’s not quite as fancy looking as the 67 TB storage from last year… but it does look pretty easy to build at home.

Modchip Hacks PS3 Via USB Port

It’s been a long time coming, but the video above shows a modchip circumventing the PlayStation 3 security by running a game from a hard drive. The sites Ozmodchips.com which sells the modchip, and psx-scene.com which has confirmed them as working are both unstable right now due to heavy traffic. But here’s what we know. The device is called the PS Jailbreak and can be used to dump PS3 games to the hard drive of a PlayStation3 running the most current firmware (3.41). Dumped games can then be played from the hard drive by selecting them from a menu that the modchip spawns. It’ll cost you though. The current preorder price is $169.99 AUD or $147.47 US dollars with a projected delivery date of August 27th.

Xbox 360 Hard Drive Adapter (redux)

July 19, 2010 by Jakob Griffith 24 Comments

[Chlazza] let us know about their Xbox hard drive to SATA adapter, allowing the use of an Xbox 360 (original) hard drive on a PC without voiding the drive’s warranty. Looking for a fun and enriching experience read: really bored and inspired by a previous adapter we featured, [Chlazza] set out to make their own and ended up succeeding with a board that costs less than $1 in parts. Of course the drive uses its own Fat32 based file system so there is still some hacking to do if you intended to read the data, but this is a step in the right direction.
