All the jpeg files are photos from a Canon 10D camera shot on a compact flash card (the photos are native jpeg format by the Canon camera settings) and imported directly as jpeg files via USB2 to the hard drive. Photoshop is the only program I use to open and enhance the files. Some files are "saved as" for the web or as eps format for print. However, they become separate files.

Some of the corrupted files have never been opened because they were never selected for publication for whatever medium. The strange thing is that I have thousands of files on the same media drive (not on the system drive), but it is only random images that are corrupted. It some cases, it's the entire folder of files and in some cases it's just some files in a folder. I have only noticed this recently as I went digging for arhival photos. All photos were taken within the last 12 months.

I am not saying it's Photoshop, but it is my primary image editing application. I did upgrade a couple of months ago from Photoshop 7.0 to the Adobe Suite with CS, InDesign and others.

I do have Macromedia, Premiere Pro and other media applications on the Dell 650 workstation.

I have not had trouble opening avi files and other media files. However, it is distressing to think that your valuable jpeg images can be randomly corrupted.

I do know that I have at least previewed the corrupted files at some point because when I import the files from the compact flash, I am sure to view them as thumbnails.

However, the corrupted files cannot now be viewed as thumbnails nor of course as filmstrip (cannot generate preview message is displayed). They remain as tiles or icons in thumbnail view which is how I am now visually identifying the corrupted files. Then when I try to open the tiles I get the "Invalid JPEG Marker" message.

This problem needs to be understood and remedied.
