Hi all,

This happens to me every now and then: I get weird lines and colours when I import a RAW file. I'm using Lightroom with Canon raw files on an iMac.

I can see the image in my Finder (would be the embedded JPG thumbnail preview) but when importing it to Lightroom it goes very weird.

Here's a screen shot:

IMAGE NOT FOUND
IMAGE IS A REDIRECT OR MISSING!
HTTP response: 404 | MIME changed to 'text/html' | Byte size: ZERO


Any ideas on how to fix this?

It's data corruption. The cause is either a faulty memory card, card reader, cable, or perhaps faulty ram. It's really difficult to work out where the problem is though.

Damn. So not salvagable at all? It's not that important for this particular shot but I'd be gutted if it seemed like a great photo that was ruined.

Just tried using Adobe DNG Converter in case it was Lightroom doing something weird, but same result as a .dng file.

Nope, it's file corruption. Are you using a cable to your camera or a card reader? What type of reader and cards are you using? How are you doing the copy/import?

Hi Tim,

I'm using a firewire cable from a Sandisk Extreme Reader. They're Sandisk CF cards and I do a copy & import from within Lightroom to a networked storage drive.

Also tried opening in Adobe Digital Photo Professional - I can see the JPG again but it cant convert & save the raw file to anything else.

Next time it happens try that card/reader/cable on another machine. You could also try replacing the reader and cable with something different, a Sandisk USB reader perhaps. You'd better download and check all your images in future before you erase your cards.

Good call. I might still have this card with the images on it.....I cycle through them every week or two.

But yes will try a different combination next time it happens, hopefully can work out the issue!

Cheers for the help Tim!

Usually it turns out to be the card, so if you have other cards, put them in and run them extensively to see if the problem persists. If it does not, the card is bad, but Sandisk does have a warrenty. If it persists, well, try other approaches!
