VISTA :-( Emachine T5234

Postby Smurfcorpse » Wed Mar 05, 2008 7:45 pm

My wife has a new PC. I installed 5.04 FAH console as a service. This has happened twice now and on different projects.
THE PROBLEM
A power loss caused the project to start over from 0. Each time both projects were over 90 % done. I have XP running the same type of projects and they suffered the same power loss but picked up where they left off.

Is this a Vista issue or a hardware issue? Can I stop it from happening again?

I don't have any advice on how to prevent this from happening again... I'm just offering a shoulder to "cry on". I had the SAME THING happen today on our old G4 mac. 2 cores... the machine likes to crash (has done so for a couple of years now - crashes no matter what's running). When it does it will sometimes restart folding from ground 0. I was 98% done on one WU and after a former restart the other WU was 24% done. BUMMER.

Thanks Myth :crybaby: It happened again last night. At 78%.

I may have figured it out on my own. In the power save settings the hard drive was set to turn off after 5 minutes. I always set that to never but hadn't on this PC. I'll post back if that corrects the problem.

Check that machine has NTFS. If it has FAT32 expect to have work restart from Zero after power loss. I've converted all my machines to NTFS, now I no longer have that problem.

Ensure that you have set a 'checkpoint' of maximum 15 minutes or so.. where the progress is saved in a "hard" file.
The F@H process needs to load the entire process string for working its magic.. not just "sections" of the equation.

Power glitches can be very annoying.. and cause loss of data. The only way to avoid such instances is with a 'line tamer' or UPS. But may add to operating costs.
A typical PSU has less than 1/2 second of reserve when the AC mains incur a "blip". Too bad larger primary caps aren't part of their design.. with at least a full second of reserve.
Your electronic gear in the rest of the home may not notice such glitches. But if they act weird or unresponsive, pull their power cord.. for a good 15 seconds. Then restore and reset. Should be no more problems.

I have FAT32 setups on both my W2K systems.. for compatibility with other systems' access. Have not had any serious problems with lost WUs, unless the power takes a gulp. I prefer to have my F@H processes as non-service launches. Create links from a folder, and add to the "Start Up" listing. They will auto-start, but not be dependent to the OS performance as dedicated services. I start mine from the desktop links, manually.
F@H.. to solve mankind's maladies.. in our lifetimes!
