Well one of my computers, http://setiathome.berkeley.edu/results.php?hostid=7965534 and this is the new designation, took two real hits last week.
First on a reboot for an update, it errored by saying the HD was no longer UEFI and it could not boot. After spending 3 days trying to restore an image I had, but constantly getting messages about either OS was not UEFI or disk was not UEFI I was able to restore the image. (You see every time I went into the BIOS it would tell me the HDs and DVD would be altering their status as UEFI or not). All this made no sense to me. The image was just going on a month old so I lost all my SETI tasks, but at least I thought I was working again, even if loosing 300 WUs.
Well it happened again on the W7 computer. I then tried to install W7 again but it kept telling me the disk format was incorrect and I kept trying to Clean it without success. Thinking that perhaps this was because the disk did not have SP1 on it I decided to change MBs and processor but the disk was still wrong, so I loaded W10 and it worked.
I then combined computers by name and lost another 300 WUs. Those extra 600 WUs are not all ghosts as there were a lot of them that were waiting for validation but I am sure there be many that will just have to time out.
Sorry to any of you who are waiting on me.

No worries,

I'm still waiting on that Ningana Prince to send me 3 Million Dollars.

a small tip: I always delete hdds with GParted or PartedMagic boot isos, before installing.

e.g. i reject the last win of 1 Mio Australien $, must be about 5 years ago :D
