"verify" in RPM returns problem files in nearly 60 packages after new install

[Harrison]

I installed Mandrake9.0 earlier this week the install seemed to go well. However, after discovering 
that my modem wasn't working (because of unidentified serial port, ttyS*) I tried to run setserial. 
I then discovered that setserial and isapnptools weren't installed. I then decided to check all my 
installed packages with gnorpm. As well as the two missing packages mentioned nearly 60 packages 
had file problem files. "verify"  showed problems with these files ranged from md5sum, to 
modification time, to file size, to file mode, to group.

Can anyone tell me if I should reinstall the packages with the file problems. If so should I use 
the --force option with the rpm install.    
thanks
