JPEG's Suddenly Corrupt on Hard Drive
"Max" wrote in message news:WkxXh.123717$DE1.122180@pd7urf2no... : : Yes, I am using XP and I rebooted. I reinstalled Canon's Zoombrowser : and I can see the pics in thumbnail form but when I select to view the : image, the image becomes blurry and won't open fully. The images are : protected-read only. Maybe that had something do something? I spoke too soon. The corrupt pics taken with my Canon A80 were able to be viewed as a thumbnail only in Zoombrowser. The corrupt pics taken with my SD700 were shown as broken images in Zoombrowser. |

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'? |

Thanks Haviung read the posts up to now, I will suggest two things: 1. Your hard drive is going bad. 2. You didn't make backups. The first is bad; there are probably other files farkled you haven't found yet. The second makes the first *very* bad; without a backup, you have probably lost many files. When you say, "perhaps when they moved from one directory/hard drive to another", which was it? From one directory to another, or to another drive? -- THIS IS A SIG LINE; NOT TO BE TAKEN SERIOUSLY! Hillary Clinton and Barack Obama and John Edwards stumped in Iowa Sunday. They all pandered to the farmers. Hillary Clinton called for crop subsidies, Barack Obama called for more ethanol and John Edwards had a four-hundred-dollar corn row hairstyle. |

I also keep photos on my laptop until I either print them or decide I am not going to print them. I have not found DVD*/-RW or CD-RW to be reliable for long-term backup/storage of files. Ron |

What does everyone do here for backing up their pictures? Do you use DVD? What brand and series (type)? This whole thing does indeed sound strange. Perhaps there was a short term hardware problem. IMHO - CRC errors are not acceptable. If you're seeing errors, you have a problem. As to backup - I read from the memory card onto two different computers - one desktop and one laptop. I also copy to an external USB hard drive and backup to CDs. |

JPEG's Suddenly Corrupt on Hard Drive

I'm having the exact same problem. All of my jpeg files dated before March 2001 are damaged. They won't show the thumbnail in windows explorer and won't open. Just curious on the dates of your files. They used to open for me on this current PC running XP but now won't, I'm wondering if it has something to do with the date and a possible critical update. There are no obvious critical updates that would break the decoding of a valid JPEG file. Something may have happened at a specific date that damaged all JPEGs on the machine (most likely a virus infection). Hardware and driver faults are non specific and tend to damage all large files - although some file types are more resilient to damage. You would be amazed how long you can live with a system for wordprocessing which very occassionally saves a blank space or null instead of a text character without noticing it. I wasn't aware that I was having this problem until I ran a backup with Norton 360 and all of these files were deleted from the backup. Could it be a Norton 360 issue? Maybe it doesn't recognize them and is blocking them from being opened? If you use Norton utilities then damage to JPEGs by its particularly inappropriate image file recovery strategy is quite hit and miss. Some of the time it latches onto embedded thumbnails as the main image rendering the bulk of the data inaccessible. "Max" wrote in message ups.com... I have many JPEGS that were working fine previously but now are corrupt, perhaps when they moved from one directory/hard drive to another. When attempting to view in Windows or Irfranview or any other program they all show as being "can't determine type". Any idea how to get the pics back? There is a good chance that you cannot. And you should worry about any other precious data on your system and make a backup of all the good files ASAP. Filesystem problems can cause large files to get damaged. It is a very bad sign if the system says "can't determine type" - most times the JPEG header and the thumbnail are the only parts that are still valid when an intermittent error affects bulk data storage reliability. The candidate faults in rough order of likeliness a Imminent Hardware Failure Bad Driver Software Filesystem Corrupt Virus infection Dodgy Utility Software If you send me a pair of consecutive damaged images I can diagnose if there is any realistic prospect of recovering them. And whatever you decide to do be sure to backup the system before you do anything irreversible. Various commercial image recovery programs may be able to help, but you could end up burning your bridges if you chose unwisely and the program tramples over the essential information needed to make a proper repair. At present just using the machine could be overwriting "empty" disk that actually contains missing parts of your JPEG images. Regards, Martin Brown |

What does everyone do here for backing up their pictures? Do you use DVD? What brand and series (type)? I have used Diskkeeper for some years with no problems. Not to say nothing could go wrong, just that I consider it rather unlikely. The only corruption problems I have had here relate to sending files to my wife's computer via the LAN, and saving them to a USB 2.0 HD on her machine. It seems the computer is just not able to handle all that data, and some corruption happened. The USB 2.0 drive died recently, so that is no longer a problem. As for backup; I save the pictures to three computers, and upload most of them to Webshots. I have had really BAD results with saving to CDs. |
