CHECKDB стал выдавать consistency errors.

CHECKDB found 0 allocation errors and 2 consistency errors not associated with any single object.
CHECKDB found 0 allocation errors and 2 consistency errors in table 'sys.sysrowsets' (object ID 5).
CHECKDB found 0 allocation errors and 2 consistency errors in table '(Object ID 99)' (object ID 99).

CHECKDB found 0 allocation errors and 4 consistency errors in table '_InfoRg6357' (object ID 2133842914).
CHECKDB found 0 allocation errors and 64 consistency errors in database 'v8_expa'.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.

При этом как-то странно, от дня ко дню их кол-во сначала четко уменьшалось.
305, 297, 283, 278, 277, 40, 64, 64

Почему кол-во ошибок может уменьшаться?
Увеличиваться - понятно, а вот уменьшаться - за счет чего могут?

CHECKDB запускали так:
DBCC CHECKDB (v8_expa)

Раз запустили с repair_rebuild:
DBCC CHECKDB (v8_expa, repair_rebuild) WITH no_infomsgs executed by sa found 40 errors and repaired 0 errors. Elapsed time: 0 hours 18 minutes 1 seconds.

Была еще раз такая ошибка:

Message
SQL Server detected a logical consistency-based I/O error: incorrect pageid (expected 1:662916; actual 1:1973636). It occurred during a read of page (1:662916) in database ID 8 at offset 0x00000143b08000 in file 'D:\DATA\v8_expa.mdf'. Additional messages in the SQL Server error log or system event log may provide more detail. This is a severe error condition that threatens database integrity and must be corrected immediately. Complete a full database consistency check (DBCC CHECKDB). This error can be caused by many factors; for more information, see SQL Server Books Online.

Ошибок файловой системы нет, ошибок в других БД, которые лежат на том же диске - тоже нет.

Что посоветуете предпринять?

Гавриленко Сергей Алексеевич, благодарю за ответ.
Как посоветуешь переливать объекты в новую базу?
