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."

      Air bags have explosives in them!

      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.

    Improving durability of laptops is more important than kicking up clock speed or what have you, at least to the truly mobile user. Especially good would be if that durability could be made cheaper.

    Something I've always found strange is that laptop carrying cases don't ever seem to advertise how well they PROTECT the laptop, which should be their primary goal, IMO. After having to go through great lengths to repair a new and expensive laptop after a drop, I'd be very appreciative of a carrying case that had this important end in mind.

      Spend those bucks on a ruggedized laptop, like the Panasonic toughbooks, or one from dozens of other vendors. I work in the public safety field and use them all the time (ie; laptops in police cruisers). They're out there, and they're friggin indestructable. They also cost more than a comparable machine in a plastic shell, ie; the LCD is behind quarter inch plexi, the case is made out of hardened steel, the internals are mounted on shock absorbing rubber doodads, etc..

      You get what you pay for in the end.

      You can cough up 3 grand for a cute and trendy iBook, or for a virtually indestructable brick.

      Oh yeah, before I forget, they weigh a friggin' ton as a rule. Weight is a big selling point for mobile users.
      • Actually, the iBook only costs about 1600 bucks, with a nice, medium-level setup (640MB ram, 60GB hard drive, extra battery, DVD/CD-R drive). And it has a ruggedized hard disk (rubber mounted) and a polycarbonate shell, with a magnesium frame.

        They're nice. Not as tough as what you're talking about, but then, they are much more powerful.

        And, ruggedized laptops don't let you use iTunes and an iPod to manage your music collection.

        • You're probably wasting your time; I strongly suspect that the grandparent poster is an anti-Mac fanatic. You can show that sort tons o' data to prove that by every reasonable measure of usefulness for a laptop, including toughness, you get more for your money from Apple than from any Wintel vendor, and they still won't believe you.

      I'm not sure if this is still the case with IBM laptops today but my A20m had some really nasty overheating issues.

      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.

      I highly doubt IBM would make this technology a "dead stop" measure. More than likely, the drive that parks itself in a 10th of a second also returns itself to operation just as quickly once the conditions return to normal. I'd say it's similar to setting your HD to spin down after inactivity, but the platters don't even have to stop turning, just the read arms move out of the way to prevent a head crash. More than likely you wouldn't notice this protective measure kicking in, which is just how it should be.

      Um. Head parking is not a permanent state requiring a reboot to get out of!

      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.
    • Any PC (desktop and laptop) made in the last 5 years can set the power saving to spin down the hard drives after inactivity. It's completely harmless to the OS. It'll pause if it's waiting for disk data, but it resumes once the drives spin up. IBM's feature only parks the heads, not spin down the drive, and it'll resume even faster because it's just seeking the head, not stopping and starting the spindle motor.
    • That's what RAM is for. Buffer your interaction with the data until the HDD comes back online. Problem solved.

    • I hope this thing isn't too sensitive - it would be quite annoying if a bumpy car ride or turbulence on an airplane would interrupt any hard drive activity...

      Why? If the plane or car ride is so bumpy that your drive might be damaged, wouldn't you prefer a temporary "drive not ready" message instead of a permanent one? It's not really like an airbag in that it's a one-shot deployment-- it just parks the drive when it senses problems.
  • by jnguy ( 683993 )
    Hm, if only there was something where it would switch to a backup battery for the harddrive to spin down, so that you don't have to fsck if you use ext2, That would be something I wouldn't mind purchasing.

    I can see how this would help if you dropped it from a table, or your briefcase, but what do they have to help the laptop that reaches its terminal velocity? It's not accelerating, so it'll unlock the drive, and then SLAM! your data's gone! Skydiving with a satellite connection may not be popular at IBM, but hey, think of the rest of us, you insensitive clod!
    • I think you're mistaken - it's going to detect the change in acceleration the instant the laptop hits the ground, then activate the "airbag". It doesn't matter if the laptop was falling at terminal velocity or not.

    • If your laptop reaches terminal velocity, the survival of the hard drive head is going to be the least of the problems with that thing once it decelerates.
    • If it reaches terminal velocity and you expect it to survive, then presumably there is some external mechanism for slowing it back down such that it can survive. I would also presume that if it starts slowing down too fast to keep working, the mechanism would engage during deceleration as well.

      A good deal more than you would think. Ever have a bad sector on your hard drive? Ever know about bad sectors on your hard drive? Those are two very different questions.

      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.

    I filed a disclosure at IBM (Kingston, NY) in the early 90's on this exact idea. The problem was during the review it was clear that nobody at Kingston knew anything or was interested in disk drive technology (San Jose did the disk drives then), so it was a no go on the idea. The disclosure is on file, IBM keeps paperwork forever.

    Interestingly enough, Connor came out with a disk drive 6 months later that did something similar, but it just cut write current rather than park the heads.
