Replacing Macbook SATA drive - urgent answer please

[Shorty]

Hi, me again.

Right, tomorrow I will be replacing my 200gb hardrive with only 15gb free on it, for a newly purchased WD 500gb disk.

I have read blogs/seen vids etc of how to do this, but I have on question.

DO I, keep the old internal HD inside the laptop, put the new HD into the external enclosure and partition the disk and then do the superduper complete info swap onto the new disk OR do I place the new HD inside the laptop, place the old HD in the external enclosure and THEN partition the HD and do the backup[I wil be able to run the OSfrom the backup won't I...?]

Thanks

You can't boot from an external drive, so do the former.

Watch your earthing too when dissembling the laptop.

Of course you can boot from an external drive - You just hold a key down during the boot sequence (Option key I think from memory). It will show you all connected bootable drives, just pick the one you want and off you go.

I must have done something wrong then.

I couldn't boot from my existing drive in a usb enclosure. [no show on booting+option]

Still, the former method above worked perfectly well for me.
