CRC32 Hash Missmatch

Dear Group,

I am trying to calculate a CRC 32 checksum with Mathematica 7, it seems that:

Hash[data, "CRC32"]

gives different values opposed to:

FileHash["datafile", "CRC32"]

"Hello, World!"//
StringToStream //
FileHash[#, "CRC32"]& // IntegerString[#, 16, 8]&

Out[613]= "ec4ac3d0"

In[615]:= "Hello, World!"//
Hash[#, "CRC32"]& // IntegerString[#, 16, 8]&

Out[615]= "a776c351"

Bug or feature or different generating polynomial ???
