IBM Introduces 'Air Bags' For Laptop Hard Drives 269
Ruger writes "Reported in PCWorld this morning, IBM has introduced a technology for their new laptop hard discs which has a similar concept to airbags in cars. Active Protection System (APS) is a microchip put on the system board that senses acceleration. It parks the head of a hard drive inside a tenth of a second, significantly reducing the risk of damage to data. IBM also has a a press release on the new ThinkPad R50 and T41 models that include this technology, for those interested in the company line."

The honorable Senator Orrin Hatch should be interested in the project as it might help realize his dreams of exploding computers. You could use the explosives to save the disk when it is accelerated, or to blow up the computer when a copyright holder presses the self destruct.
BTW, if they really are like airbags, the devices can only be used once. However, what realy matters with analogies in business press releases is to make investors think of other market successes, and not really about the product.

The way it cools the CPU is via a tiny horizontaly mounted fan and a heatpipe running through a big aluminum block...which did virtualy nothing.
Worse yet it was fairly common for that fan system to die. There was a controller card which regulated the fan based on the CPU temptriture. In my laptop that part failed three times during 2 years. Worse yet the ONLY way to fix it is to replace the mothereboard, $400 (the fan itself which can die is $50).
I personaly find it odd that they're so concerend with HDs. I dropped that very same laptop numerous times and that never resulted in a damaged HD or even damaged plastic. (I can't say the same about Dell laptops)
10 Hour battery life on the other hand is something I'm curious about.
Also another HUGE weakness IMO are ports.
Like keyboard, network, USB etc. On a PC those ports are used maybe 10 times a year, on a laptop several times a day, at times roughly.
My current laptop can't play any sound because the 'sound out' port is broken (it's all made of plastic, cord got yanked sideways and the plug just shattered). A friend of mine has a useless laptop because the ethernet jack is broken. I have seen plenty of dell and IBM laptops where the powercable refuses to stay in.
Personaly I'm baffled how the designers didn't see these issues comming.
Fact is the laptops are NOT used gently for more than the first few days. Then they get tossed about and "ripped out" of networks at the end of a long day.

In fact you can have an unsaved text document open and after some inactivity the head in the laptop drive will get parked automatically. With modern mobile hard drives this is likely to happen in as little as 30sec of idling. This does not in any way mean that your data is lost. Once you have the need to use the hard drive heads (for purposes such as saving data) they will be unparked promptly.
i/o systems generally have some notion of buffering and can also cope with latencies (just think of a network socket) so that even in the case of a blocking write operation no data is lost even if the said blocking will take any measurable period of time.

Re:how many... (Score:5, Insightful)
Modern hard drives have extra space available on them reserved for remapping sectors that fail. The drive can detect these failing as the voltages from the heads fall when reading data. At the first sign of this, the drive logic reads the data, moves it off to a reserved sector, maps it internaly, and goes on about its business. Now, there are a few things that can cause this.
First off, there is straight manufacturing errors. Less common than they used to be (hdd's used to come with tables of bad sectors printed on thier label) but they do happen.
Now, they can also occour when a read head is literaly floating microns above a spinning platter revolving at around 3000 rpm's. Whack that drive with a hammer and the head could contact the media, effectively scratching the disk. Depending on the severity there may be no damage, a bad sector could begin to form, the head could be damaged, or the drive could be shattered to bits.
Moving the head off the platter (or towards the center depending on thier parking mechanics) will almost eliminate problems resulting from the head contacting the media.
Now, parking the head will not add any stability to the drive, but it will greatly increase the g's a drive can experience before being damaged.
