If there are no objections, seeing as there is little interest in this drive, I would like to reserve the remainder of the files on this drive.

No objections, IMO, but please keep us informed about your progress. For example, when you reach n=1.8M.
At the end, please send results to the address given in the first post, not to me. Thanks! 
will do as requested, will start the search in the morning. :smile:

Currently at 1.81M (no primes)

Thanks for the progress report, that's very fast! :surprised
Note that at about n=1967k you will have next FFT length jump, from 163k to 196k. And here is the list of all 36 Ks being tested by the drive. [CODE] [B]389152177 536864983 691459721 410314627 540196717 713633533 414322661 552455201 725433403 432043439 564510097 738297163 443200949 567143683 759833699 463395913 578625847 801584081 482987411 589877983 811064503 491362811 609937687 814419757 493412999 651488009 835596479 494660219 660879671 851324377 531115657 667868189 855686399 535224337 673503191 857656417[/B] [/CODE] 
Beyond completed all 4165 tests in the 1680k2M range, but found no primes.
Thus after 2 years and 10 months, the 3rd Drive is over. Thanks to everybody who contributed. Will unstick the thread shortly. 
So there were ~9000 tests with no prime in this drive. Did we ever estimate the number of expected primes from the drive?
Many of my reservations are lowerweight kvalues, and I wonder sometimes if they produce lower primespertest results than "normal" kvalues. I suppose it's just small sample, or the humannature wish for betterthanaverage luck. Curtis 
I do not have excate figures but "back of envelope" calculations from all the low weight K's I've tested suggest the average is 1 prime / 10,000 candidates. YMMV

I'm quite happy to notice that the 3rd drive has been finished after it was stuck for more than a year. Unfortunately we didn't hit a prime in this drive. :cry:
Some of our longterm members might remember that I had another [URL="http://www.mersenneforum.org/showpost.php?p=61631&postcount=45"]bunch of 23 lowweight k[/URL], which I tested beyond n=2M. During the last two months I did some extensive sieving and will reach p=100T by the end of this week. I also did some LLR testing and I'm close to n=2.5M now. Once reached p=100T the whole bunch will consist of about 61000 candidates (in the n=2.510M range), which is still too much for a single person to test in a couple of years. Therefore I'm willing to donate this bunch of k for another drive. Let me know about your opinions... Thomas
