The Azure OS disk size specified for the virtual machine is too large?

Question

I have VHD file (actually downloaded from Microsoft: http://www.microsoft.com/betaexperience/pd/BIVHD/enus/). I want ot run it as VM (IaaS) on Azure. The file is 60 GB when I upload it to Azure with this command:

csupload Add-Disk -Destination "http://xxx.blob.core.windows.net/vhds/SQLImage2012Disk.vhd" -Label SQLImage2012Disk.vhd -LiteralPath "E:\SQL Image 2012\SQL Image 2012\Virtual Hard Disks\SQLImage2012.vhd" -OS Windows

I see that it is uploaded, but the size is 250 GB!!!?

Why the size has expand so much?
Because the size is 250 GB I receive this error message when try to provision virtual machine from it:

The OS disk size specified for the virtual machine xxx is too large. The maximum supported OS disk size is 128 GB, but the VHD specified has a size of 250 GB.

The questions are: Why the size change from 60 GB to 250 GB ? What can i do to manage to provision VM from this disk in Azure ?

thanks in advance

The answer from the comment is the answer: "From your description it seems this is a dynamic VHD that was set at a maximum size of 250 GB, with 60 GB used. "
