Bootable Backup Questions
So I have read through all of the forums and I am not sure what I am missing.

I am trying to make a backup of my MacBook 100GB hard drive.

I am using a Thecus N1050 (maybe this brand is the problem? I can't find which chipset it uses)with a 100GB drive inside.

I started with this from another posting:

OK. If you're on a USB drive, please use the GUID partition scheme (Options button in the Partition tab of Disk Utility), since you're only going to be starting up Intel-based Macs from that drive.

Then, make sure you erase the drive and use the "Mac OS Extended" format.

However, the last part doesn't seem to work right. If I follow this order, when I verify the disk (click info) it shows that it is not using the GUID partition scheme - but using Apple Partition Map.

If I erase first, then partition, select the GUID option, it shows up as GUID partition scheme and I begin.

I have tried this a couple of times following the rest.

Once that's complete, Smart Update the external using "Backup - all files". Then, select the drive in System Preferences' "Startup Disk" preference pane.

When you watch it start, see if you get a grey screen, Apple, spinning "pinwheel", etc. A blinking cursor at the upper left isn't something I'd expect to see at all.

I have to deviate slightly here, as my version is not registered and i can't do a Smart Update (I am evaluating this software to see if I indeed can make a bootable backup before I buy). So I choose the option to 'Erase MacBook Backup, then copy files from Macintosh HD'.

On successful completion: Do Nothing
Advanced - no options selected.

Then I sit for two hours or so and it completes. However, I have not been able to boot from this drive. I tried two different methods.

1. The method suggested above by selecting the disk in the System Preferences.
2. Rebooting and holding down the 'option' key and the hopefully selecting the disk manually - but it isn't available as an option.

Any thoughts as to what I am doing wrong? Any additional information I can provide?

I'd love to buy this software, as all the reviews and personal recommendations have told me it is the one to go with. However, until I can get a bootable backup, I am going to keep looking for other options.

Thanks so much for your help.

It definitely sounds like the drive isn't supported by OSX, Trebz... is it a FireWire or USB drive?

The drive is USB 2.0.

The manufacturer says the drive is supported for OS 9 and later:
Windows ME/2000/XP
Mac OS 9.0 or later
Linux kernel 2.4.x and above

The drive connects, works, makes a copy, etc, just that I can't boot from it. I am currently trying to clone the drive one more time to make sure I just didn't screw something up.

That being said, I am not 100% attached to this. The reason I bought this drive is because it also can be used to copy USB drives, as well as being able to dump digital camera pics right on to the device (it has an optional battery pack).

Assuming the latest clone doesn't work as a bootable copy, I can continue to use this drive/case for this purpose, and buy another case. Can anyone recommend a 2.5" Firewire or USB 2.0 case where I can insert my own 100GB IDE laptop drive (which i already own)?

Anything with an Oxford chipset should work fine...

Can anyone recommend a 2.5" solution cheaper than this?

OWC Mercury On-The-Go FireWire Portable Kit W/ Oxford 911+ Chipset - $59.99

Thanks again. BTW, for my Mac Mini Desktop - I just successfully created a bootable clone on my 500GB My Book Essential USB 2.0. I guess its time to buy SuperDuper and start doing the regular scheduled backups.

Thanks for the support and any suggestions on the enclosure question.
