Hi

We use Dynazip to make file on diskette but when a diskette is not good dynazip continue and return true (true mean succeed!).

We try to check file opening with low level function and reading file. It works well and detect defect if we change diskette and return to the diskette that as an error. If we don't change the diskette between dinazip and reading file with low level function no error was found because file is read from memory of system instead of diskette.

Can we flush system memory with an API or use another way to check diskette and see if there is a defect.

Thanks

Michel
