Thanks for the advice

The bios does not recognise the drives which is why I changed the lead to a
brand new one. Still can't see them.

Tried system restore - no joy

Looked at the manual article - when I go into the registry it has higher
filters but no lower filters.
The article said that if there were no lower filters then it wasn't of help.
Not sure if I should delete the higher filters anyway ?

"The bios does not recognise the drives"

Surely, that is a crucial step. If the BIOS doesn't see a storage
device, that severely limits the possibility that the OS will be
able to. No amount of UpperFilter changes will change that. The BIOS
gives you hardware visibility. If you haven't put the data or
power cabling or jumpers together right, or enabled a storage controller
in the BIOS setup screen, then fixing it to work properly at the
BIOS level, is your first step.
