I don't think I trust the Acard adapter. I've not read many
encouraging reviews of it.
If I don't get the Firm Tek, I'll get the adapters.
Are the adapters as reliable as a SATA PCI card? I think I'd rather
get the PCI card over the adapters if I can use larger
drives.

I don't know how to do it in AppleScript, only that it might be 
possible.  The other option is to look around for some utility that 
would do it.  A search for "internet sharing dock mac" might do it.

But surely *just* before it does this, it knows it is going to do  
this and so this could trigger some information, perhaps worded much  
like your explanation here, perhaps even suggesting things like to  
look in logs etc to the machine user or at least to name the last  
instruction in plain English that is causing it to pull the plug.  
Even the Rain Man used to say things before a big panic: "Uh oh, uh oh!"

I think Jörg meant to include a link pointing towards something like this:
http://www.nowthatsit.nl/categorie.asp?categorie_id=629

The advantage of SATA <-> PATA converters ... when they work ... is
that it works at level so low in the hardware that the operating
system isn't really aware that it is there. So you shouldn't ... in
theory ... have to worry about whether firmware is compatible with
your MAC or not.

I've had good luck using converters to continue using PATA drives with
a SATA motherboard. Whether or not the ones to convert a PATA socket
for use with SATA drives would work for you I can not promise. But you
might want to consider trying it. (Or not).

What does Internet Sharing have to do with iChat?  And why the mad dash?

Internet Sharing is for turning the computer it's on into a router. 
This let's you share your Internet connection with other computers.

It may be possible to set up an AppleScript to do this which could then 
be put in the dock.

Why do you have to do this? Does iChat not work if you're sharing the  
internet?

Why do you ned to share the internet from your computer? This is work  
much more suited to devices like wireless or wired routers.

You should just get an adapter, I use two of them to connect cheap
1.5TB drives, they work like a charm. They should cost around 10
Dollars. ATA-drives are mostly 500GB max. and cost the same as much
bigger SATA-drives.

My SATA drives connected via the adapters are quieter than my ATA
drives and as fast if not faster. I use these adapters:

Power and heat go hand in hand.  All the power that goes into your drive 
turns into heat.  So if it draws more power it will generate more HEAT 
and that means it will get hotter.

Another aspect of upgrading a hard drive that is usually overlooked is
the bit density of the platters. Roughly speaking the newest drives
with the highest densities will usually net you better performance
even at "only" 5400 RPM. The reason being that the drive platter
doesn't have to be moving as fast in order to read/write a large
quantity of data when the bit density of the platter is higher.

Within reason, I would always recommend going with the latest drive
technology with the highest platter bit density that you can get and
worry about 7200 vs 5400 as a lower priority. You'll get more
performance bang for the buck with a higher density platter. And if
you get a large drive that only uses a single platter it is also
likely to use less energy.

Just some thoughts for whatever their worth. I realize that since
you're (I assume) looking a for a PATA 2.5" drive your options are
more limited.

Which for drives older than a few years old than a new one is commonly  
the case.

So far (only a few hours of use) my new Hitachi 7200 RPM drive seems  
to run about as cool as my old 5400 RPM Samsung one...which is to say,  
pretty warm, actually :-/

You can reduce this remarkably by doing a custom install. If all you  
want are the applications, which have a lot of useful stuff in there  
you can forego everything but that applications, which brings it down  
considerably.

Leave out Documentation (which is all available online) and you get  
back almost 700 megs.

Or use something like Pacifist and just extract the utility if you want.

If you know how to use Pacifist,  an alternate way than to install all  
the XcodeTools.mkpg (2.41GB) ...

Using Pacifist > Open Package

Navigate to

Optional Installs > Xcode Tools > Packages > DeveloperTools.pkg (click  
Open)

Then Drill Down to

Applications > Utilities > USB Prober.app

and Extract.

Re: hard drive speed in an iBook G4 12"

Howdy,
  The higher RPM drives are definitely faster.  It does not always make
sense to use them.  They have two negatives.  They usually draw more
power. And, they are hotter.  The extra power is rarely a problem, but
it does come up.  The heat is the real killer.  You should look up the
specs on your old drive and compare them to the new faster drive.  If
the bearings or motor efficiency have been improved, it could be that
the new drive won't put out enough extra heat to be a problem.  And, you
may be prepared to live with the drive dying sooner, in order to get the

just say consider the factors and make the decision that is best for
you.
Good luck,

I believe its called USB Prober.app.

I'm installing it now by running the XcodeTools.mkpg package off my OS  
X Leopard Install DVD.

I've always appreciated the detailed info that is given, in dynamic  
mode ... but the Developer folder is over 1GB, and I didn't have room  
to keep it up before installing my newer SATA drives.

Re: Question about USB ports?

[Richard Gerome]

   I'm just guessing here, but I'm thinking what it is seeing is just whats on 
the mother board and your computer can run 5 built in USB's and a couple are of 
the high speed type, there may be an empty slot for another 2 USB's if you only 
see 2 or yours or you can change it out to a card with 4 USB's for an upgrade 
??? If there is 2 on the keyboard they run though the port where you plug in 
the keyboard, in which case maybe would be piggy backing them to the mother 
board??? Keep in mind this is just a guess on my part, I don't know the 
workings of that computer???  CoolKat

There are USB busses that are not associated with external ports.  My 
C2D iMac has three USB ports, but reports five busses - three for the 
external ports, one serving the internal Bluetooth controller and IR 
receiver, and one apparently not in use.  As for the reported speeds, 
that is affected by what is plugged into the port.  The port I have 
my external hub plugged into reports as high-speed, while the other 
two are dragged down to 12 Mb/sec by the keyboard hub and cell modem, 
respectively.

The ports on the keyboard are just that, ports, not busses.  They are on 
the same bus as the port the keyboard is plugged into.

The way the system reports busses is strange.  I don't know why it does 
what it does but it does change the reporting of high speed busses 
depending on what you have plugged in.  It seems to overlap the "high 
speed" and low speed busses.  That is it reports 4 low and 1 high but 
that high is really the same as one of the low speed.  I tried to figure 
it out once on my iBook and just found more confusion.

There is a USB diagnostic tool, part of XCode, that is more detailed and 
technical but less confusing once you get past the details.  IIRC when I 
looked with that it was clear, but it's been a while since I did that 
and I can't recall the specifics.

I think in the OP's case there are 4 busses, one for each of the three 
ports and one additional port, either a connector on the motherboard and 
or used by hardware built into the motherboard such as BlueTooth.  Even 
if the machine doesn't have BT there may be some support for it on the MB.

For example, this MacBook Pro.  ASP shows 5 "USB Bus" (lo) and 2 "USB 
High-Speed Bus" (hi).  Now 2 lo and one hi are used internally for BT, 
keyboard / trackpad, IR receiver and iSight.  Leaving 3 lo and 1 hi not 
tasked and two external ports on the MBP.

If I plug in a USB 2.0 card reader it appears on the previously untasked 
hi bus.  If I switch it over to the other port it now appears on the 
same bus as the iSight.  With a mouse plugged in to the first port, it 
shows up on the same lo bus with the BT controller.  That is it is 
plugged into the same connector that the card reader was plugged into 
and appearing on a hi bus.

I guess the one hard piece of data is that the ASP list is screwy.

No, the only thing that Disk Warrior does is rebuild munged disk  
directories. It does it very well. It does not do any sort of  
'undelete'; it'll see a freshly formatted drive as having no files on  
it, and faithfully rebuild the empty directory.

Jason, please keep in mind that system profiler only "sees" those USB

Your tower has 3 usb ports. Your keyboard has 2 non powered ports on  
them. The other part of the question, the USB high speed bus. The best

File Recovery Query

[aussieshepsrock]

Hi Group,
   I have formatted a drive (simple format - no zeroing out) when I
meant to zap a partition. I haven't lost anything of 'importance', but
can I use a utility program to scan the drive's sectors and
reconstitute the data onto another drive? I seem to remember using
Disc Doctor back in the day to do something like this under OS9. I
immediately shut down the computer and pulled the drive, well, after
exercising my 4 letter vocabulary for a moment, so the drive is
untouched except for the 'format' command from disk utility. It would
be much easier to recover the drive than reconstituting from a
plethora of opticals.
Thanks

Going up in speed makes a useful difference. Going up to 5400 or 7200  
is definitely worth it.

I just replaced a dead 5400 rpm drive in my TiBook  with a new 7200  
rpm one and it's got 'teh snappy'...particularly noticeable when  
starting up or loading programs.

Hi!

I plan to replace the 60 GB hard drive in my iBook G4 12" laptop with  
a larger one.  What I have in mind is a 250 GB drive.  My question is  
whether more RPMs makes a lot of difference in overall computer speed
