When booting from the new disk with the old disk connected does the old disk:

- Appear in Disk utility?

If it does are the parameters list seem reasonable?

- If shows in Disk Utility does it also show in Finder?

If it does, can you browse the disk?

- If it does not show in Disk Utility does it appear in System Profiler under SATA/SATA Express?


If it shows in Disk Utility but you can't browse in Finder then

Try a disk recovery app:
