need help - assignments did not transfer properly
 
Hi everyone, I have a rather serious problem.

I had to transfer a few P-1 assignments to another computer because my father asked me to remove Prime95 from the old one (what a killjoy). Unfortunately, something seems to have wrong during the transfer, as some of the essential files (such as worktodo.txt) are not showing up on my thumb drive.

Thankfully, I was able to transfer the save files to the new computer (although they later disappeared from my thumb drive as well).

Now here's the main problem: how do I make Prime95 continue an assignment without the correct worktodo.txt file?

I know that the worktodo.txt files for P-1 assignments look like this:

Pfactor=<some hexadecimal string>,1,2,<exponent>,-1,68,2

However, Prime95 will not continue an assignment if the hexadecimal string is left blank. Is there anything I can do in this case? Are there any ways I can retrieve the correct hexadecimal string?

Thanks.

OK, I followed the directions from [url=http://mersenneforum.org/showthread.php?t=12383]this thread[/url], and Prime95 restarted the assignment instead of continuing where it left off. What the hell?

I routinely sneakernet P-1 save files from my low-memory room heater to my main box without problems, so I know it's possible. Obviously I can only guess at your problem.

Corrupt save file? That they "disappeared" from your thumb drive does not inspire confidence in it.

Different versions of Prime95?

I was transferring from a Windows laptop to my MacBook Pro (both are/were running version 25.11). In the worst case, I'll just have to redo the P-1 assignments. I do suspect that my thumb drive is corrupt, though.

I think I know what may have happened: the USB flash drive actually had a folder named Prime95, so the computer created a new folder named [I]Prime95 - new[/I]. However, for some reason, the computer copied from the Prime95 folder that was already on the USB drive instead of the local hard drive. I had assumed that the transfer was successful, so I deleted the copy on the hard drive.

Note to self: always make sure that the files have reached their intended destination before deleting the old copies.
