Have the same problem with both my computers:laptop (pavilion dv6t) and Desktop (pavilion SR5450F). E:drive (dvd) has disappeared in both computers after I installed the recommended windows updates for my VISTA O/S. . IS THIS A KNOWN BUG? The drive is recognized by BIOS firmware, (disconned and reconnect cables) but does not display when I click on computer. The following drives do display when I click on computer. C, D, and Norton Backup Drive. If I plug in a USB Flash Memory.stick it shows up as an E:drive. : Please help,. I need the Dvd to load all
my software drivers and applications.

Hopefully waiting you reply.
