Ways to analyse root disk slice

Hi,

Recently I faced with need of analyze root disk. I figured out two possible ways to do it:

1. Practical. Boot from CD and run format
2. Theoretical. Create live upgrade boot environment on another disk, activate it, reboot, unmont all root disk partitions and run format.

I've already used first way and my question is if the second way can be done in practice

No it can't directly. The ABE would be built using the existing root disk so you would most likely fail to build the ABE.

reborg
And if root slice is not damaged?.. Will I be able to perform full system disk analyze if ABE is built successfully? In case that swap space is moved from system disk to another, whether system disk is in use when booting from another ABE from secondary disk?
incredible
If you're asking what is ABE, ABE is Active Boot Environment
