If I reinstall Vista, is there a way to create a Toshiba recovery disk once I have got the laptop working to my satisfaction, ie with all drivers and ancillary software loaded?
If you install own Vista version you will not be able to create Toshiba recovery disc.
Only when Toshiba recovery image is installed on your notebook you can create this disc.
What you can do now is to install own Vista with all necessary drivers, tools and utilities and use some third part application to create recovery image. Many people here have reported that good application for recovery image creation is Acronis.
You can also try to order original recovery disc from Toshiba.
