notebook harddrive anti-shock

[tsubasa23]

Hi,

a lot of notebook has hd anti-shock technology where it will pull out the read/write heads when it senses movement. is this tech part of HD? or is the sensor somewhere else(or both).

i own an fujitsu A6020 and wanting to replace my notebook hd for a faster/bigger one. i am wondering where i will lose this features if i replace it?

thanks in advance

IBM ThinkPads where I work have have a G-force sensor in them. As best I understand the technology when the drive senses acceleration above an acceptable level it parks the HD heads and braces for an impact. Just having one bouncing around on your lap is sometimes enough to cause this behavior. I believe with the ThinkPads there are various levels... in normal state a HD icon in the lower right corner is green. Give it a little shake and it turns yellow. I'm fairly certain that if it's dropped it'll turn red and do everything necessary to brace for that impact. Pretty smart what machines can do.

As best I can tell from these IBMs, it has nothing to do with the drive... in fact, I'm almost certain of this. Our ThinkPads here contain a variety of hard drives, yet they all have this functionality. I just don't think the various HD manufacturers would build what is essentially a custom hard drive for a limited number of manufacturers. I think you should be safe with a replacement drive, but I recommend a call your laptop's manufacturer to verify this.

Some HDs do have sensors some do not.
