Newb: JPEG's Suddenly Corrupt on Hard Drive

From one directory to another, or to : another drive? It's hard to pin-point exactly. Back in December, I installed a new CPU and MB. There were a lot of CRC errors that I detected in my old system, so I changed my IDE cable. The CRC errors are acceptable now (very low). I did back-up my files before the surgery, BUT to another [slave] hard drive. Not to another form of media. I did reinstall Windows XP. OOPs, you should not see *any* CRC errors; there is no "acceptable" number. I will suggest this is where your files got farkled; you have a bad drive. Yesterday, I ran through (very thorough) diagnostic procedures and tests for my hard drive that has my JPGs currently loaded. Everything is fine. Except the files are farkled. What I am also thinking is that perhaps when defragging my hard drive my Diskeeper software maybe didn't move files correctly or corrupted them somehow? No, I seriously doubt that. I've never heard of that. Fortunately, I have many (not all) of my pictures also stored on my laptop. There is a loss but this is a big learning experience that I don't want to go through again. What does everyone do here for backing up their pictures? Do you use DVD? What brand and series (type)? Personally, I'm of the school that says whatever you do is better than the best solution that's not used. IOW, do *something*. I have an external drive that's synched (using MS's Synchtoy) with an internal drive, then I use TrueImage monthly, and I also back up my images (and other important files) to DVDs that are stored in my gun safe. And that's still not enough, probably. It's been my experience that the burner is more important than the DVD disk itself; use a cheap burner, and the disks tend to go bad faster than using a good burner and cheap (in my case, I use GQ from Frys with great success) disks. YMMV. -- THIS IS A SIG LINE; NOT TO BE TAKEN SERIOUSLY! Hillary Clinton on Tuesday compared herself to the famed escaped slave Harriet Tubman who fought to help fellow slaves escape the South through the underground railroad. Who is she kidding? Hillary Clinton has never taken the subway in her life. |

I have about 50 or so folders in "My Pictures" and was dumbstruck one day when I went in to make some prints of a couple of pictures that I had used many times, only to find that about half of my folders showed up as empty!! The folders were still there but no pictures!! Never did figure it out, but I also use Picasa2 and discovered that the missing pictures would open up in Picasa. After a lot of dragging and dropping, I was able to get most of the lost pictures back where they belonged. Later I started noticing that many of the "lost" pictures were showing up again in other folders or that some of the "empty" folders were showing back up with duplicates. Craziest thing I ever saw!! Still haven't figured it out. Big John |

If : you're seeing errors, you have a problem. CRC errors are not as bad as one may think. CRC errors are RARELY an indication of hard drive errors, rather it's a symptom of a bad IDE (hard drive) cable. |

Thanks First, in Windows, moving a file from one directory to another does NOT copy the file data. It only changes a pointer. Moving from one drive partition to another will copy the data. Your problem may indicate something starting to go wrong with your HD, or its controller. Good luck. Can you spell 'BACKUP'? Did they get rename3d and lose the .jpg? |

The View on Disney-owned ABC dropped Rosie O'Donnell, even after she agreed to stop talking about George Bush. The president has no leverage over ABC. Disney is not a defense contractor, unless you count the war rationales we buy from Fantasyland. |

I had many problems with courrupt jpgs when using FAT 16 and FAT 32 and very few since switching to NTFS. I've had drives fail using both. OTOH out of a total storage capacity of over 5 terabytes I've only lost 3 drives that I can recall. They generally get replaced with something larger before things fail. |

No, that's an incorrect assessment. I used to think that way. I have contacted a lot of hard drive techs and they all said get a new cable, which is what I did. CRC errors are non existent any more. I suggest anyone concerned about CRC errors (some are always normal) to download Hard drive tune and click on Health of your drive. You may be surprised with the number of CRC errors you have if you have a bad cable. The link is he http://www.softpedia.com/get/System/.../HD-Tune.shtml |
