Hard drive problems

I have a WD 500Gb internal hard drive on my Macbook Pro 2.4GHz with Lion 10.7.2. After I got some problem with my hard drive I tried all kinds of ways to repair it. Techtool, Diskwarrior, Disc Utility. Nothing could repair it. Then I decided to re-format the hard drive and restore with my TimeMachine backup.

But I could not even erase the hard drive.I also rie to make partitions without luck. Now I got my new hard drive and installed it with no problems. But the problems I have now is:

1. The new internal hard drive restored from TimeMachine don't have the "Recovery HD" partition as Lion provides. It's just gone?

2. When I used the old hrd drive in a external USB casing it's working fine, and there was no problem to erase, format and use the disk again?

Can I get the Recovery partition back some how? And any ideas what's going on?

Thanks!

Macbook Pro 2.4GHz, 3Gb RAM 500Gb HD, Mac OS X (10.7.1), Powerbook G4 Alu 1.5 Ghz and G4 Quicksilver 867MHz

Disconnect the TimeMachine drive.

Connect the external USB enclosure with the old hard drive inside, see if you can hold the option key and boot from it. If not, then use another Lion Mac.

Download this software here:

Get a 1GB+ USB thumb drive, format it GUID OS X Extended in Disk Utility > Partition Tab

Run the Lion Disk Assistant software to copy the Lion Recovery Partition to the USB thumb drive.

Take that to the "new hard drive Mac" and option boot off of the USB, you will need a strong fast, reliable internet connection to install Lion.

Hold command r keys to boot into Lion Recovery Partition.

Big thank's for that help. But I'm still confused why I could not erase the old internal hard drive when it was in the machine. It makes me thinking that maybe the hard drive was not the problem. But what else could it be?

(I have Lion on an external drive so I used that to boot and ried o repair/erase from)

Sometimes they have trouble dismounting the old drives, usually if I get this with spare HDDs I just diconnect all other drives, boot in to the Recovery Partition and do the permissions repair which sorts it.

Is this issue resolved now Mats?
