Lost Work due to hard drive failure

(moderation:
My computer recently had a few problems and I apparently lost a decent sized portion of Work Units For the Einstein@Home project. Is it possible for the work units to be downloaded again (or put in a queue) for me to compute again? Or is it possible to erase those entries from the user log on "My Account" page or "Mr Results" page?
Thanks,

On your account page on the website, your computers list shows three similar boxes. Are these all just the one physical box or do you really have three separate machines. If they are separate machines, which one had the disk crash?

Mr. Roberts,
I went ahead and tried to reorganize the data that you are writing about the multiple computers being listed. To answer your question, the BOINC software has been operating on one computer the whole time, yet as to why there are multiple records for the same computer, I don't know.

Scott,
You've done a great job as I can see under your account page on the website, the results lists of the three previously listed CPUIDs which now have been nicely collected and merged together all under just one CPUID. Well done!!
Now the good news is that the five shown in red are all expired and will disappear from your list in the not too distant future. The ones shown in black have all successfully completed and gained you credit. The ones shown in green are the ones you should be able to see on the work tab of your BOINC Manager window.
You don't need to be concerned at all about the five red ones. If you click on the Work Unit ID for each one, you will see in each case that three other crunchers have completed the work, have been validated, and have been awarded credit. So all is perfect and the work is all finished. In fact, these sort of little accidents are the very reason that 4 results are sent out in the first place. You see here, a good example of the system working perfectly!!
The problem of multiple CPUIDs can occur for a variety of reasons. Essentially your computer was accidently registered with the EAH project two extra times. These accidental duplicate registrations have now been cleared up by whatever action you took and there should be no further problems if you just let BOINC do its thing.
I notice you are using version 4.45 and there is a newer recommended version with a number of useful improvements now available. The upgrade is very easy and, I believe, quite worthwhile. There are instructions at the top of this board in a sticky thread. I also notice from the pattern of messages recorded for your successful results, that BOINC starts and stops very frequently. I'm just interested to know if you have the preference set for only doing work when the computer is idle. Can you tell me if that is correct, thanks? Also is EAH the only project you support or do you have others?
If you decide to reply, please drop the "Mr Roberts" nonsense :) ;).
Cheers,
Gary.
RE: I notice you are using

- I went ahead and upgraded BOINC to 5.2.2. Wow, that was easy to upgrade. As per the work usage times, I used to have the BOINC system run only when the screen saver was active, then I kept on getting errors when the computer would be in "screen saver" mode about some weird memory addressing errors, so I decided to have it run as a "background" process and I haven't had any problems since then.
Possible unrelated note: I was testing out the E@H beta test (ver 0.18, I think) because I have an ATI Radeon 9600 Pro graphics card because I couldn't see the visualization of the E@H project. Now, I am using a test run of the standard E@H client (ver. 4.79) to see if there are any differences in computation or errors and such.
- I am currently doing 4 BOINC associated projects at the moment.
LHC@home, climateprediction.net, Einstein@home and SETI@home
- As you wish. I guess my parents ingrained that concept into my head when I was in grade school and I naturally do that now. My apologies on that.
Congratulations on the

Congratulations on the successful upgrade. As you say you have BOINC 5.2.2 and Einstein 4.79 now running and your first result with this combo has been validated with no problems. Also I see that your crunch time has reduced approximately 10% which is a bonus as well. So for the moment all is well but if you get any "Client errors" due to graphics bugs you may have to go back to the beta app. Sooner or later that beta app will become the standard science app anyway.
Good luck!!
Cheers,
Gary.
