Disk error message since updates 10/29

Hi

Since yesterday (updates 10/29), I frequently get error messages about disk
access when starting Windows. It seems a program try to access a disk which
is not present.... Sometimes, no error message appears. Is there a known
problem with these updates ?

There is no detail in the windows logs.... Error 26, Windows Error Disk
Popup...

Thanks for your help and sorry for my bad english....
