Bought this:

[forums.macresource.com]

for my C2D MacBook.

Stuck it in an external case, cloned internal to external, then physically swapped drives.

The WD crashes at grey Apple screen with the message:

"-sh :edWide: command not found
-sh -2.05b# CDRHIDTransitionDriver::stop
IOBluetoothHCIController::start Idle Timer Stopped"

Disabling sudden motion sensor has no effect - same error message.

I wonder if the WD is drawing too much power.

The WD takes 30 seconds to get the grey Apple after power on, but only 1-2 seconds for the Seagate (5400.3, not 5400.2)

The WD is rated at 0.55A, the Seagate at 0.487A

Any other thoughts?

>>Any other thoughts?

Drop in the OS X install CD and run disk util on it. perhaps try a clean install.

i doubt its drawing too much power.

Do you have another Mac? Clone your original drive to a disk image using Disk Utility on the other Mac. Pull the original drive out, install the new one and restore the drive in Disk Utility from the image you created on the other machine.

Does cloning a drive copy the Intel specific partition data?

In tha 360. MRF User Map

I'm not sure what you're asking, but the method I mentioned is exactly what I had to do to mine as my 160GB Hitachi drive I was replacing with the 250 would not work in the USB enclosure.

>>Does cloning a drive copy the Intel specific partition data?

No, thats in the partition map, which is a small amount of information describing the formatting of the drive and possibly some information for booting.

Yes, the drive should be formatted with the GUID (?) partition map.

You can clone a drive, but it only clones the content.

Did you format the drive for an Intel Mac? If you didn't do that first, it could be causing the problem.

I use this procedure to create bootable external drives that have clones of the internal drive. I've used this successfully when replacing a hard drive in an iBook.

1. Format the new drive in an external case by using the Erase command in Disk Utility. (Any other way of erasing the contents did not yield a bootable disk.)
2. Clone the currrent internal drive by using the Restore command in Disk Utility.
3. Repair permissions on the new drive while still in the external case.
4. Swap drives.

You should be good to go from there.

Ditto on the GUID thing mattkime mentions above.

I'll try reformatting with the Intel GUID scheme, but I'll note I did not do that with the Seagate and it boots just fine (partitioning scheme: Apple Partition Map)

Thanks for all the feedback!

GUID is the answer :>) Right Zoidberg?

Good Luck!

The MacIntels can boot from both GUID (Intel) and APM (PPC Macs) formatted drives, but if you have to do a FirmWare (EFI) update it will fail.

BillInNC, try these steps.:
Put WD back in external case.
Format the WD as GUID Format.
Use SuperDuper to clone your MacBooks internal HD to the WD.
It is free for this use. There are other software packages, but this is what I use.
When done, try booting from the WD in the external case.
Also, double check that the WD is in the GUID format before swapping HD's around.
Whatever is failing it is not a power draw problem.

I'll have to remember all this, as I want to put a 250 gig drive in my new MBP.

Damn!
Another badly formatted HD from Apple.
I don't know what is going on at wherever they build these things but this is now the tenth one that has had APM instead of GUID formatting!
Boots, runs fine until you have to do a FirmWare (EFI) update.

Yeah, for whatever reason, probably legacy code that never got taken out, some Intel Macs will boot from an Apple Partition Map-formatted hard drive. But it causes the kinds of intermittent/non-reproducable problems BGR is talking about, along with others.

Not some, all. The OSX installer disc is APM!
Great article about all this crap.:
"Intel-based Mac Boot Incompatibility"
[rentzsch.com]
GPT = GUID Partition Table.
APM = Apple Partition Map.

I also replaced my Macbook drive with a larger one. However I user SuperDuper! to make a bootable copy on the external (new) drive, then swapped them. Worked perfectly. I formatted the drive first using the same partition scheme that was on the original. That's the important point or your drive won't work.

Let's get this straight.
The MacIntels Will Boot from an APM Formatted HD.
The OSX Installer Disc is APM Format.
Go ahead, check your MacIntel install disc, I'll wait!
Good, see that. This is what mine reads.:
Partition Type : Apple_partition_scheme
Whatever problem you are having BillInNC, it isn't from the formatting, I am pretty sure it is how you're "Cloning" the data over, you seem to be missing drivers.
If you could please give us a wee bit more data about your methodology?

When I say clone I mean I'm using the "Restore" function in Disk Utility, after I repair permissions on the source (source=internal Seagate, destination=WD in external USB case)

I have now manually repartitioned the WD w/ the Intel partition scheme and am restoring as we type.

Checking newegg's reviews, there are some other issues with this WD model.

Slightly OT...is it possible to boot a MBP from a USB2 HD or must it be FW?

You know that rule of thumb that says when you get a bad clone with CCC, use SuperDuper and vice-versa?

The same thing goes when a Disk Utility clone fails. After erasing the drive, try CCC or SuperDuper.

> Slightly OT...is it possible to boot a MBP from a USB2

Intel Macs can boot from USB drives.

Slowly...at least in my cheap 2.5' USB case.

While the Seagate worked fine with the default Apple partition scheme, this model WD won't boot reliably unless you make sure to manually choose GUID partition scheme when setting up the drive, as most of you thought.

DIsk Utility still works fine for cloning drives.

Thanks for all your help!

>Intel Macs can boot from USB drives.

Bill in NC, is this the Newegg review to which you're referring...

[www.newegg.com]

I can't identify the specific WD drive inside the Costco enclosure. Links?

Sorry, people are reporting SMART failures (so they pull the disk for replacement):

[www.newegg.com]

I'll keep an eye on my WD.

It sure is quiet.

got the same drive/macbook popped it in wiped the drive did a clean install then moved my stuff over. sounds like a user problem try my steps.
