Hard drive shuts itself off after detecting the laws of gravity

Samsung Electronics today introduced its new M80 SATA Series and M80 Series 2.5-inch hard disk drives. Both series utilize Perpendicular Magnetic Recording (PMR) technology, feature an optional free-fall sensors and offer increased storage capacity. Both the M80 SATA and M80 Series comes in 80GB, 120GB and 160GB sizes. 

Samsungs newest 2.5-inch drives offer users increased damage risk protection by incorporating free-fall sensors, which feature a minimum fall detection rate of 30cm. Hard drives enabled with the sensor are able to detect changes in acceleration caused by a freefall, and park the drives head on the ramp and turns the hard drive off, protecting it from damage.

The M80 SATA and M80 Series feature an 8MB cache and a 5,400rpm spindle speed and comes equipped with the Hybrid Latch System, a mechanism that eliminates rattling noises and reduces the clicking noise generated when a drive moves its heads on and off the disk.

The M80 SATA and M80 Series are Samsungs first hard drives based on PMR technology. Unlike traditional longitudinal recording technology, which lays data bits end to end where they can flip and corrupt data on the disc, PMR technology places the data bits perpendicular to the disc, which reduces the corruption factor. In addition, by placing the data bits standing on end, more data can fit onto a disc, allowing for greater storage capacity.

Other hard drive manufacturers have already made headway in the area of PMR technology. Seagate launched 2.5" drives with PMR back in January, and shipped the first 3.5" PMR drives three months later. In May, Hitachi joined the perpendicular ranks in mobile storage with the a new Travelstar. Fujitsu followed during late summer with its MHW2 BH hard drives, and Western Digital with its new Scorpio SATA drive.

when i drop my laptop from and minimum of 30cm the hard drive is going to be the least of my worries :S

omg i know! that's what i was thinking! like that drop feature should work at 10cm or 15... like seriously if i drop my laptop past 30cm then i'm going to be VERY worried about the screen, cpu... really all of it.

The point is that at least now you won't have to worry about losing your data as it'll be protected. I mean you can easily replace a screen, but sometimes losing data can just be hard/impossible or very time consuming to replace.

Not if you have important data stored on it. Everything else is replaceable.

By definition, if that data is "Important", it isn't only stored on a laptop hard drive.

Unless you have valuable data on it...

no offense, but that's like saying if you use a car to get to work everyday, you deserve to have it break if you don't have a spare in your garage

Not really, no. Backing up data is free, fast and easy. Anyone who doesn't do it can only blame themselves when they lose data. That said, every bit helps.

my poitnt entirely, backing up data doesn;t mean having a spare computer it just means putting it on a floppy.

i personally have never once had my harddrive in mylaptop braek yet have had my entire laptop smashed up, i am far more concerned with the screen than th harddrive. the harddrive is remarkably robust and it is a simple 30gb drive, not even a perpenticilaur storage jobby

no offence but graity is a constant so surely it would remain forever off according to this statment :D

The article said:

Hmm, 30cm is not a "rate". Did he mean to say a minimum acceleration? 30cm/s² is a lot less than 1g (~9.8m/s²). This is confusing.

I hazard a guess that it means that if you drop the laptop containing the hard drive, after falling for 30cm the hard drive will have protected itself.
