Borrar file y file group tabla particionada - Transact-SQL

[Libras]

Lo que pasa es que cuando hiciste el switch de la particion moviste los datos que estaban en la particion 1, normalmente la particion 1 se reserva para el sistema, y no estas revisando en que particion estan tus datos, prueba con este query para obtener el numero de renglones por particion y revisar cual es el numero de particion que quieres mover:

Código SQL:

SELECT
DB_NAME() AS 'DatabaseName'
,OBJECT_NAME(p.OBJECT_ID) AS 'TableName'
,p.index_id AS 'IndexId'
,CASE
WHEN p.index_id = 0 THEN 'HEAP'
ELSE i.name
END AS 'IndexName'
,p.partition_number AS 'PartitionNumber'
,prv_left.VALUE AS 'LowerBoundary'
,prv_right.VALUE AS 'UpperBoundary'
,CASE
WHEN fg.name IS NULL THEN ds.name
ELSE fg.name
END AS 'FileGroupName'

ahora mencionas que el dbcc marca errores, que tipo de errores??
