When running Verify in MSC, you may come across an error that states something like this:

“Error:Problem on BLOB # 27644 in the Resources data table : BLOB checksum is invalid(10;33)”

Although the error may seem to be pointing to the data file, it is actually referring to the Resources table of the structure file (.4DB). The Resources table is an internal table used by 4D to store different resources such as methods, forms, and menus. The error should be fixed by performing a Repair on the Structure file. Having a backup is recommended as some forms, methods, etc., may be lost during the repair.
