I have done following stupid mistake.
1. I'm with Mac Ox 10.6.4 (New Macbook white) and I have had window OS A: (30GB) and H: Data (100GB) C: Mac OS (120 GB).
2. I have accidentally deleted A: and B: drive in Mac OS. ( I was trying to only delete A: drive T.T) So it is just C: Mac OS (250GB) remained.
3. I hope to recover H: (100GB) using testdrive.
I have following problems while using testdrive.
1. write access for this media is not available. Testdrive won't be able to modify it.
I have used Sudo in the first page and type my Mac password (is this correct?) But still above message appears.
2. Anyway, I have ignored and continued and quick search and it says the harddisk (250GB/232GiB) seems too smlall! check harddisk size: HD jumpers and settings, BIOS detection.
Could you please help me with this...

Also, how to insert images in this page?
