Problem transfering the blockchain

[Bakemono]

Hi i tried to transfer the blockchain from my laptop to another computer.

I copied all the blk*.dat and rev*.dat files from the c:/.../bitcoin/blocks folder into 2 dvds and then in the .../bitcoins/blocks folder of the second pc.

The problem is that when i opened bitcoin-qt on my second computer it gave me an error msg about the blockchain and started downloading the chain from the beginning.

So what am i doing wrong?
(actually i m not even sure if all those .dat files are the actual blockchain but anyway)

Thank you.

You only need to transfer the blocks and chainstate folders between the bitcoin directories.   You missed the chainstate folder.

bitcoin databases are not portable. you need to use detachdb before moving the databases.

Wasn't that changed in version 0.8.0?
