Fragmentation of Table Differs Between 2000 and 2005 Client on 200

I'm examining the logical fragmentation for a table running on SQL Server
2000. If i run dbcc showcontig the fragmentation appears as 0.21% however if
i examine the same index in SQL Management Studio 2005 it's 20.64%. So which
one should I believe?

Exactly which fragmentation figure are you referring to?

|||The algorithm for calculating fragmentation is different in SQL Server 2005.
The new algorithm is more precise, so the fragmentation values appear higher
in SQL Server 2005 than in SQL Server 2000. For example, in SQL Server 2000,
if a table has page 11 and page 13 in the same extent, it isn't counted as
fragmented. However these two pages will cause two physical IOs , so in SQL
Server 2005, this is counted as fragmentation.
