I was running bitcoind from my Linux box. I stopped the command when ~/.bitcoin size was about 5.8GB.

Today I started the daemon again. ~/.bitcoin size is now 7.2GB. Here is says that the blockchain weight about 6GB: http://blockchain.info/charts/blocks-size.

Is that webpage wrong? Maybe bitcoind is downloading everything again and mixing both downloaded block, thus increasing the size to more than the stats at blockchain says.

A call to getblockcount returns: 225531

EDIT: I've found the total blocks count here: http://blockexplorer.com/q/getblockcount (228972). I guess blockchain.info is not updated.
