The 2000GB IPod You Wished For In The 00’s Is An ISore

Remember those times we all said that we wouldn’t mind it if the iPod was three times as thick but could store a lot more songs and the battery lasted forever? Well, the I-Sore will let us truly consider our stance on the subject.

The iSore would have definitely made some of us the coolest kids on the yard in Jr. High (or at the engineering office) in the 00’s. At first glance we assumed it would be one of those fancy single board computers packaged with a big hard drive masquerading as an iPod. We were surprised to discover that [jimbone] was performing a classic iPod hack.

The ipod’s back is pried off and discarded. A ZIF to SATA adapter connects it to a significantly larger hard drive. The basic battery is replaced with an 8Ah pack. The USB ports are broken out. For the case there are a few options. There’s a 3D printed case, a wooden case, and even one that looks like a Lovecraftian horror.

[jimbone] claims 100 hours of playtime on a single charge. He hasn’t claimed bulking up a bit from carrying it around, but we can make our guesses.

SSD Hard Drives Tank Laptop Battery Life


Tom’s Hardware has been running some tests to challenge the common assumption that SSD hard drives use power more efficiently than magnetic plate drives. Their results were quite definitive: not only are they not as energy efficient, SSDs actually use more power than conventional hard drives.

What they found is that most plate drives are at peak consumption (up to 4W) when accessing files fragmented across the media, which causes the actuator to move back and forth across the media several times. However, this is almost never sustained for extended periods of time; the actuator usually doesn’t move much when reading unfragmented data, and most plate drives are also capable of going idle when they are not in use.

Most SSDs on the other hand, only have two states: on and off. This means that when they are on, they are always at peak energy consumption. Though this number hovers around 2W for most of the SSDs they tested, over prolonged periods this can mean a great deal more power consumption than is immediately apparent, which can have short and long term effects on the battery life of a laptop. See the Tom’s Hardware article for benchmarks of specific products and more in-depth data.

Data Recovery Tools


In your zeal to delete your data, you may have accidentally deleted files that you wanted to keep. Lifehacker has posted this handy list of data recovery tools to help you get those files back.

As you may know, whenever you delete a file, the only thing that changes is the file system. The data of the deleted file is still on the hard drive, but the file system sees the space containing the file as “blank” writable space. Data recovery software typically looks into the directory where the file was stored and scans it, finding any files not listed in the file system.

The program you choose for this task will not only be determined by your OS, but also by the specifics of your recovery needs. Do you need to recover a single file? Many files? A whole hard drive? An unbootable drive? A really scratched optical disk? Specialized tools for all of these needs are available, and this article will help you find the right program for yours.

Drive Slagging


Maybe you wiped your iPhone by filling the hard drive with music, or maybe you used a more sophisticated method. In either case, your phone is clean, but the hard drive in your computer is still chock full of evidence of your misdeeds (or just personal emails to your mother). If you fear forensic analysis will expose your wheelings and dealings, then a full format is not enough; you’re going to have to obliterate the plates inside the hard drive.

To that end, [Eecue] posted this worklog of slagging a hard drive. Using a propane powered furnace, he melted most of the drive’s components by placing it in a steel crucible which was lowered into the furnace. After a few minutes everything but the steel casing and a few bits of woven fiberglass from the PCB were melted down completely. You can see the entire process in [Eecue]’s drive slagging photo album.

With solid state drives becoming popular and their inherent difficulty of assured erasure, physical destruction is looking like a lot more reasonable option. As you readers have stated in the past: it’s certainly a lot more fun.

Obsolete Technology Band


Radiohead held a contest for fans to remix the single Nude from their album In Rainbows. Frontman Thom Yorke mentioned on NPR that the contest was essentially a joke, since the Nude track is recorded at 6/8 timing and 63bpm, much slower than traditionally mixed music. The above video from [James Houston] is one of the most creative entries. Using old computer hardware he has recreated the track in a very unique way. He uses a Sinclair ZX Spectrum for the guitar track, a dot matrix printer for the drums, a scanner for bass, and a hard drive array for vocals.

Breaking Disk Encryption With RAM Dumps


If you haven’t gotten a chance yet, do watch the video of this attack. It’s does a good job explaining the problem. Full drive encryption stores the key in RAM while the computer is powered on. The RAM’s stored data doesn’t immediately disappear when powered off, but fades over time. To recover the keys, they powered off the computer and booted from a USB disk that created an image of the RAM. You can read more about the attack here.

How can you reduce this threat? You can turn off USB booting and then put a password on the BIOS to prevent the specific activity shown in the video. Also, you can encrypt your rarely used data in a folder on the disk. They could still decrypt the disk, but they won’t get everything. I don’t think this problem will truly be fixed unless there is a fundamental change in hardware design to erase the RAM and even then it would probably only help computers that are powered off, not suspended.

The potential for this attack has always been talked about and I’m glad to see someone pull it off. I’m hoping to see future research into dumping RAM data using a USB/ExpressCard with DMA access.
