Yesterday an Apple Certified Macintosh Technician installed an SSD into my iMac medio 2011. The iMac was born with an 1TB HDD but now a Crucial M4 SSD is also installed inside the mac. I've moved my OS X to the SSD using the OS X Recovery, where the OS was installed using an Time Capsule Backup. Afterwards I did an Erase of the old HDD in Disk Utility to remove my old OS and my data has now been transferred to new, clean partition. Afterwards I inserted my Lion DVD and did an reinstall of the OS X to get the OS X Recovery partition created on my SSD. The name of the partition on the SSD is Crucial M4 SSD and the name of partition on my old 1TB HDD is Storage.
Please see this output from diskutil list:

- Why do I have an Apple_Boot on disk1 after the entire disk was erased?
- What is the EFI and Apple_Boot?
- Is it normal that the type of the Recovery HD is Apple_Boot?
