I just put a new Seagate 120Gb hard drive in my cube. It's supposed to have a 8Mb buffer, but it's only set at 2Mb. How do I change it to 8Mb??

I don't think it's something the user can even change. Where are you even seeing the buffer size listed?!?

That's what I want to know (how you can view it). I bet you're looking at your L3 cache.

DimeTech · Apr 22, 2004, 02:15 AM

ah...that's it...it's the l3 cache....well thats wat I meant in the original question. can anyone asnwer that?

Huh?

People above are speaking "geek". In time enlightenment will filter down to us "peasants" and a new utopia will emerge

I have a HD with an 8MB cache so any replies in "England" will be appreciated.

I doubt it's the geekspeak that was confusing, just that the question didn't make any sense. Using cache is a setting of the drive. If it's only using 2 MB (How can you tell?), that's all it has.

You don't have to "enable" it, it works whenever the drive does anything.

When the above posters mentioned your looking at the L3 cache size, they meant you're looking at the L3 cache size OF YOUR CPU not the buffer size of the HD. Ie. If this machine of yours is a G4 PowerMac each Processor could have an L3 cache of 1-2MB. L3 cache does not refer to drive buffer size. I think that's what the "HUH?" was about, you didn't understand the poster's reply.

The posters' question still stands, where are you viewing the size of your HD's buffer size?

I would think that GoGoReggieXPowars is correct in that you don't have to enable anything.

And let's not call it Geekspeak, it's perfectly correct technical terms.

There is no setting to set the CPU cache. There is no setting to set the HD cache. Both are fundamental features of the CPU module and hard drive, respectively, and can't just be set! Apple System Profiler reports the CPU cache values to you as a courtesy, to let you know the specs of the machine without disassembling it.

Just like you can't take your 4-cyclinder engine, flip a switch, and have it grow another 2 cylinders.

Though you used to be able to take your 8 cylinder Caddy and have 2 or 4 of them go offline

Kenneth · Apr 22, 2004, 02:59 PM

it's getting out of hand now..

BTW... check the label on the hard drive or in the Disk Utility... hope you didn't receive a remarked HD.

For the L3 cache.. did you upgrade your CUBE CPU? I don't think the stock config contains a 2MB L3 cache.

Actually, IIRC, that's a new feature of the V8 Northstar engine Cadillac introduced in the late 90's, but as an emergency feature. If the engine begins to overheat, it'll shut off 4 of the cylinders to reduce heat production. It can go up to 50 miles that way, far enough to make it to a service station to get looked at.

with apple's CHUD tool, you can turn it off. can't change the amount, though.

As far as the old Cadillac engines go, they were called the 8-6-4, and they were a flaming disaster. However, GM is planning on using that technology on their trucks soon to help achieve the necessary fuel mileage regulations. However, it'll be a little more advanced than the old method, God I hope so.

Several automakers are planning "variable displacement" engines. Since everything is computer-controlled now, the technology is a lot more feasible than it was fifteen years ago.
