When copying a table with blob fields, VerifyTable and RepairTable return False on a copied table.

As for the issue, there's an issue with the source table that is only being
exposed when the table records are copied over to a new copy of the table.
For example, calling OptimizeTable on the table, and then repairing the
table, will result in the same issue.

OptimizeTable, CopyTable, etc. all copy over the existing row checksums, so
they do not generate new checksums.  However, they do copy over the data
field-by-field and record-by-record, which is why these processes expose the
difference between the actual record data and the checksum that is stored
for the record.

If the table is particularly old, then the problem could have been
originally caused by this:
