Resuming after a hard drive crash

delta_t · 2003-06-25, 18:15

Can someone please help. Lost my Prime95 client after a hard drive crash. I would like to resume where I had last left off because I was about 94% complete on M19172359. The last iteration my computer checked into Primenet before the crash was 17967105. Is there a way to resume from there? Or do I have to start from the beginning of that exponent again? Thanks.

Without the pXXXXXXX or qXXXXXXX save files there is no way to continue from any one point. Alas, the beginning is whever you must start.

I see what you mean. So maybe I won't have to start from the beginning if I could locate my backups for that particular directory I had Prime95 in. Still, what a bummer, so close to finishing it.

Seems to happen to many of us sooner or later. I lost the larger half of a 19million a few months back. Thank goodness that's the only one since I started

The only (small) consolation I can think of is that you do not need to do the P-1 stage again, as if that had found a factor, you would not have gone on to do the full Lucas-Lehmer test. So make sure the worktodo.ini line ends in ...,1 rather than the ...,0 you might have had previously.
