Thanks for your great reply Nick.

I'm wondering if I should do as you suggest, backup dbase etc and do a
fresh install.
What kind of performance hit would I see by keeping the recordings and
operating system on the same physical
disk? I've seen people say this is a "no no".

If I won't loose much performance, I could use my new 1TB disk for the
install and recordings.
Then once I have restored things from the 'old' disks, I could check
these thoroughly and if they are ok I can
add them to the system for additional recording space etc.

Thanks
Mike
