Hi Doomer, thanks for the reply.
I connected to PC3000 and after a few minutes it stopped knocking and scraping and came DRDY DSC, and entered utility manually.
ROM info was read (correct version matching drive label), and module table found in ROM.
Any attempt to read ANY modules caused the drive to start knocking and scraping again and produce "drive not ready"
Any more clues?

Feel free to PM me or msn me!
Cheers
Sean
