BS. Where are you getting your info? The CPU does all the work, the HD only stores the info crunched to send back to SETI. I am coming up on my 1st yr anniversary and no problems. My main machine is the G3/300, 6 yrs old and still purring like the day it was new. Just make sure you have a good air flow through the box and everything will be fine. It is the peps that use PowerBooks that burn up your machine, probably because they don't raise it off the table to get air underneath it. I use 1/2" rubber feet and a small desk fan blowing across the unit to cool my PowerBook the fan hardly comes on. My temps never exceed 109�F in my G3.
What happens is when you are processing a work unit, the result from each process is written back to disk. Although the data units are small (about 350kb) your Mac is continually reading / writing the data from the same sector of the disk. Think of it as a bush track. Although there is lots of dirt there, over time the people who walk through there make a groove.... Do you want this to happen to a $200 hard drive?
Now, lets say that data unit is somehow fragmented on your drive. Imagine all the work the drive heads have to do to read / write a data result.
This is why you should set up a ram disk - it saves your hard drive and actually speeds up the process. It is always faster to read / write from ram than it is to a HD. ;)

edit - although I do think distributed computing is a great solution to solving problems, I can't see myself being that dedicated setting up a box fan to cool my computer so I can pump out 300 work units a year....

I am looking at purchasing a 160GB (Lacie) external drive. I have a 12" iBook with 30GB of storage (only 600MB available). I need a place to backup my hard drive and store these video files of astronomical size. Is there a difference between the d2 and Porsche designs?
- auto shutoff?
- easy syncing?

Thanks.

After some research my top 3 sorted options are:
1.- OCZ Vertex 2 120GB
2.- Intel X25-M 120GB
3.- Samsung 470 Series 128GB
I will be using it as my boot drive for Mac OS X 10.6.7, any suggestion which one would be the best option for speed ?, thanks
These are ok value for money options, try not to go with the OCz though if this article is anything to go by:
http://blog.macsales.com/9438-not-all-ssd%E2%80%99s-are-created-equal-the-story-continues
OWC, Micron\Crucial and Intel are the best brands and use the most quality components. With OWC being better than the Micron\Crucial which uses a slower Marvell Controller.

Just curious. I got my new pb and am overall very very happy with it. But i am a biologist and work that i do requires up close scrutinay of several photographs. These horizontal lines make that very annoying. If this is a software problem i wont be that discouraged, but if it is hardware i may have to get a pre-october refurb. Anyone have any insight into this issue?
Another possibility is that the problem is in the wetware. Some uses see it others don't. It might be that some hardware has it. It might be that Apple had it in the initial machines but not now. I say that because I just got a PowerBook 15" and the screen is beautiful. No lines. No flicker. No waves. Bright and crisp. I love it.

Hi guys, I just swapped my iPad 2 out for yet another new one (and flawless screen-wise; yes, they do exist!) and it turns out that it came with 4.3.1. :cool:
Being that 4.3.3 just came out hours ago, will Apple still let me upgrade to 4.3.2? I read somewhere that they do allow customers to upgrade to the immediate predecessor of a just released iOS update for a short period of time. Is this true?
Yes, I know there's no jailbreak for the iPad 2 yet, but I'm not worried about my location data, which this mini update is all about. However, I'd like to get 4.3.2 for its (supposed) battery life benefits.
It also happens to be something that I've always wanted to know how to do, i.e. upgrade to a version that is different than what iTunes serves up.
Oh, and yes, I have my SHSH blobs for 4.3.2 saved by way of TinyUmbrella, if that makes any difference. ;)
Thanks very much for any responses! :)

Prior to this G5 I'd primarily used laptops for years. Particularly like the ALPowerbook keyboard for feel. Can't stand the normal Apple keyboards, or any normal ones really. Got the icekey maybe 1 month ago. I absolutely love it. And you don't have that issue...the only one...with the Powerbook when you are typing in Word, and go to hit the right shift key, hit the up button, and delete the last line or two...hate that...have to undo quickly. Not a problem with the bigger Icekey keyboard.

Another vote here for the Seagate Barracuda if you're looking for a high-capacity drive. I've always found them to be very quiet and reliable.
If the extra storage isn't critical and you fancy a performance boost, pick up a 10,000 rpm 74GB Western Digital Raptor.

FAQ:
1) original/replacement/refurbish which one is best?
Since you have spent so much on MBP why not choose the original one.
If you bought used MBP, too old to buy a new original, you can choose Grade A replacement or a refurbish seller you trust.
2) Why I can't track original adapters from Apple Store?
If not buy from Apple directly, most time you can't. Apple don't accept it in fact, because these adapters get from OEM directly.
Trading Companies call it Gray Market, most original adapters are not brand new. QC from Apple is very strict, adapter with little scratch or even a tiny spot should be destoryed. And that's maybe what you get.
If some friends have more questions pls leave your message.

2)Serial Number
Original:
As I say before, 3 companies make adapters for Apple. Delta/Liteon/Samsung.
Serial Number like this: MV9200G9J81WA
MV stands for Delta, 9 means 20 means 20weeks. This one is made by Delta in May, 2009.
ZZ stands for Liteon, Samsung with R start.
These may change in future, and I don�t know the meaning of 0G9J81WA, if somebody knows pls tell me.
Conside manufacturer�s name is showed on case, you could check whether serial no. is the same with manufacturer. And choose the date in 2010 would be better than 2008.
Someone make high-copy serial no. please don�t choose adapters only accord to it.

If he doesn't have a 32GB iphone sealed, he won't be getting his bargaining chip back.

FW400 doesn't carry any power so no it's not going to work.
They do. That's why we had to send some DV decks back to Sony, as they were often kaputt due to the wrong order of connecting them to the computer.
FireWire 400 (IEEE 1394-1995)
The original release of IEEE 1394-1995[11] specified what is now known as FireWire 400. It can transfer data between devices at 100, 200, or 400 Mbit/s half-duplex data rates (the actual transfer rates are 98.304, 196.608, and 393.216 Mbit/s, i.e., 12.288, 24.576 and 49.152 megabytes per second respectively).[4] These different transfer modes are commonly referred to as S100, S200, and S400.
Cable length is limited to 4.5 metres (14.8 ft), although up to 16 cables can be daisy chained using active repeaters; external hubs, or internal hubs are often present in FireWire equipment. The S400 standard limits any configuration's maximum cable length to 72 metres (236 ft). The 6-circuit connector is commonly found on desktop computers, and can supply the connected device with power.
The 6-circuit powered connector, now referred to as an alpha connector, adds power output to support external devices. Typically a device can pull about 7 to 8 watts from the port; however, the voltage varies significantly from different devices.[12] Voltage is specified as unregulated and should nominally be about 25 volts (range 24 to 30). Apple's implementation on laptops is typically related to battery power and can be as low as 9 V.
