Jeff We are finding primes. Nearly all are drive 3 and found by myself. I am adding then to the bottom of my last post. As there are so few of us no one else has broken my run. We don't have the sieve files for drives 1 and 2, they disappeared with Beyond. He never shared them with anyone, just emailed work to top up the ports. I can recreate those ranges but the sieving required would be too much for me at present as i have to keep drive 3 going as well. Drive 3 i sieved myself and we can carry on with that, it will need more sieving when we pass 600k.
