Is a special hdd needed for mobile computing

I have an Acer 1820PTZ , it`s an notebook/tablet computer , I dont know if it has any built hdd drop protection , it has a g sensor to detect the screen orientation.

My question is an standard notebook hdd able to withstand being carried and given normal knocks and bumps without being damaged while operating.

My notebook/tablet came with an Seagate 160gb ST9160314AS installed but i upgraded it to an Seagate Moments XT 250gb ST92505610AS.

Thanks for any reply

John.

 

yes yes yes

 

And i was hoping it would be NO NO NO

 

the hd you put in it is fine.

 

the hdd drop protection is.. almost useless (unless you drop it from ~1 foot)

most of the time, mine just stalls my hdd, so i turned it off (built-in drop protection in laptop, not built in hdd)

 

In that case it's a little late for this question, isn't it? In any event, HD aren't designed to be knocked and bumped. That's why you laptop should remain stationary when in operation. That said, there are mechanisms, (i.e. G-sensors, at $10-$20 extra) that can give you some additional amount of protection provided you stay within it's distance to impact boundaries. There are external HD that come with special rubber accessory cases, that offer the greatest amount of protection. If you need anything beyond that, get an SSD.

 

Yes, they are. They can handle that kind of stuff perfectly fine while spinning. It is things like dropping the laptop on the floor that they can't well.

 

The original hdd did not have any built in g-protection , according to the Seagate spec sheets the original and my replacement have exactly the same shock rating 350g operation, 1000g non-operating.

Thats why i was wondering if the g-protection might be built into the notebook/tablet.

 

Ipods have normal 1.8" hard drives in them and I see people running around with them. If this logic holds true you should be fine.

 

Thanks phil

Though it looks like ipods have a higher g-shock rating of, operating 500g and non-operating of 1500g, compared to the Seagate 350g/1000g

 

Phil,

Ipods are a little 'special' in that the file/HD is accessed once very briefly and cached in RAM - that is why people can run with them (along with their higher tolerances too, of course).

If the Ipod fails - no big deal - just music (right?) - not quite the same with a notebook and possibly very important data (work/school/personal).

 

But think about it, 350 g's while operating is a lot. A spike of 350 g's is far more than a human can survive. This is well above "normal knocks and bumps." While operating, I can drop my laptop at least 2 inches above a hard surface without problems.

Another thing to remember is that many 2.5" hard drives these days come with built-in shock protection, even if they don't advertise it. I've also noticed that several laptop-based g-shock protection systems are far too cautious and freeze the computer for 5 seconds at the lightest jarring. Those are best turned off.

 

You're making a lot of assumptions, and taking a lot for granted. Nevertheless, there is a margin of tolerance when it comes to knocks and bumps, but not everybody's idea of what constitutes a knock or bump is the same. One has to wonder when they set these tolerances whether the drop is onto a solid surface of a flexible one. One things for sure, I wouldn't want to test any of those tolerances--G-shock or not--with my valuable data. Would you?

 

I'm not assuming anything unless by "normal knocks and bumps" he means "shake it like a salt shaker" or "drop it on the sidewalk."
