I've had a "fun" day.
----------------------------------------I had to replace the boot drive in one computer. The drive had developed a bad sector. I did not have the software to mark it as "bad" within NTFS without reformatting, so I decided it was "cheaper" to replace the drive than reformat and do a clean XP install. (Guess that's what you do when you have more money than time  ) After diagnostics, shopping for a new drive, and installing both hardware and operating system, that shot about 4 hours. At least I was able to image the operating system to the new drive. I only lost a few easily replaced files. Whew! Dodged that bullet!I'm also back to full power on WCG cancer. Since my day was shot anyway, I uninstalled WCG/UD and installed WCG/BOINC on the three main 'puters. I lost about 3 days of points for various reasons (including shutdown for thunderstorms), but should start cranking out the results again in a day or two. anyone need a "slightly used" 40G hard drive?   |

LH... ...sounds like your day is a mirror my past week!!!! The "Queen" went down with a HDD crash ....luckily I had a spare preloaded to slip in it (( that's rare for a lappy ))..Drone one had a Bios faiure ....spent 2 days triing to flash that!!!!....and now my WIFI is acting up!!!...luckily (( Again )) I'm good friends with my neighbor; so I'm piggy backing his WIFI until I can get it resolved ...hopefully tomorrow.... on a side note ...Scandisk should have been able to fix the bad sector issue  EDIT:.....FYI you can run boinc without uninstalling WCG/ud agent ...infact you can run them side by side ...which sometimes does...sometimes doesn't ;result in a point surge ..depending on the WU's, machine, and configs   [Edit 1 times, last edit by Sport at Jan 2, 2007 1:23:19 AM] |

I probably ran chkdsk 20 times - when run within Windows, it would find errors, but could not fix them without exclusive HDD access. But when I would run it at bootup (/F), then it never found a problem. I eventually found that some of the corrupt files were being created in Docs&Settings\Local Settings\Temp, so the "bad" files only existed when Windows was running. Since it never found anything wrong during bootup, there was never anything to "fix" according to the program. It was really weird.
----------------------------------------I even ran Gibson Research's SpinRite with its most aggressive settings, and it did not fix it either. SpinRite can recover data in sectors through repeated read-read-read and statistically decide if it is "1" or "0", but to no avail. I figure that fdisk would scan and mark bad sectors to make the drive usable again, but that would, of course, require that I copy everything to a backup hard drive first - so I just moved it to a new drive and put the suspect one on the shelf for now. |

...I'ld still try to slave the drive ...do an fdisc and try to save the physical drive!!!! That's exactly what I plan to do. However, I already have 400+ GB in unused drive space between various computers - What would I put on this puny, 40G drive?  |

Are you guys ever going to translate all this TT for me? My computer thingy was getting irritable and crabby. We thought it may have caught a cold, but it was just old and tired. I bought a new thingy to replace it before it collapsed from exhaustion, and the new one is much bigger  . After some rest on the shelf, we anticipate that the old thingy will feel better and may return it to light duty. |
