Yes in mycelium just make a backup of your HD wallet. It will give you a seed that you can later use to recover every address your mycelium makes in future (except for your legacy addresses).
I recommend making a backup of your new wallet and then transferring all of your old mycelium address bitcoins to the new wallet. With the new HD wallet you only ever need to make 1 backup, whereas with old mycelium each new address needed a new backup.
It has nothing to do with HDD like the poster above me states

ok...
i see so mycelium create single seed for all wallet created ? so where to import these master seed, i just backup and write down the seed and i cant find a way to import it.
EDIT : : : i just realize that i cannot import seed, if there already 1 hd wallet present, i ll have to delete data and/or reinstall mycelium then i can import seed
thanks
To elaborate on lyth0s response:
"Legacy Wallets" are the traditional method of generating key/address pairs. It would use a random for each key pair generated, and each address would need to be backed up, with no significant relationship between the addresses or their keys from any of the other keys in the collection.
- You MUST back it up every time new keys are generated, this includes some situations that might not be obvious to new users. Most clients store 100 Key Pairs in a 'Key Pool', when you send a new transaction, or 'Generate a New Address', or anything that utilizes or accesses a new address, it typically is taking a pre-generated address from this key pool, and a new address is generated to be added to the pool. When you back up your wallet, it is backing up all the keys used and the 100 unused in the pool. But every time you send, create a new address, etc, new keys are added to the pool, which are not included in your old backups. Once 99 new-key actions are initialized, any addresses following that would not be included in your previous backup. This has caused much dismay and confusion among new users who thought backing up their wallet once secured the balance being displayed in it regardless of address management.
- If you lose the private key(s) for the addresses, there is no way to recover or regenerate them.
"HD Wallets" AKA "Hierarchical Deterministic Wallets" are deterministic wallets that use a random 128 bit value as a seed for all the key pairs in the wallet. In mycelium this value is presented to the user in a 12 word phrase. Generation of future address pairs, or recovery of past ones, can all be accomplished through use of the 12 word phrase.
- Allows generation of public addresses without private key.
- Only one initial backup required, that all future addresses/data can be generated/recovered from.
Also as lyth0s confirms, as par the misunderstanding of the first poster, HD wallets have nothing to do with Hard Drives... A paper HD wallet can function much the same as a paper Legacy wallet : although in a more dynamic manner. A paper HD wallet can contain the seed information and be used to generate or recover all the addresses that have been or will be linked to the wallet -- where as a legacy paper wallet requires a separate key etc for each address.

thanks, that makes thing clearer.
on side note this seed thing looks like nxt wallet imho.
