Photos randomly becoming corrupt...has this happened to you?

| ->> I don't know where the problem is, so I don't know which category to put this in for equipment Q&A, so I'll just throw it out to everyone. The past few days I have had an alarming problem with photos becoming corrupt. In Photo Mechanic they display as black frames. The EXIF info is still there, just no thumbnail, and if I try to open it in Photoshop, it displays an error message & won't open correctly. At first it seemed to happen when ingesting disks, but I noticed that when I open previously existing folders of previously undamaged images, one or two are now black frames. That's the REALLY scary part. I'm using a G5 1.8 SP, OS 10.3.5, and P.M. 4.4. That's been my setup for as long as 4.4's been out, but this problem just began a few days ago. I've run disk warrior, repaired permissions, yadayadayada but it is still happening. I'd gladly send my G5 in for repair but I don't know how to describe the problem, or if it's even a problem with the hardware at all... I've posted this question on Rob Galbraith's site, since Kirk Baker is so fantastic about keeping up with tech issues on P.M., but I hoped someone on this site might have also experienced this problem and could pass along a suggestion/solution. Thanks! |

| ->> Can you open the files in Photoshop or PictureViewer? Are they from CDs or directly from CF cards after a shoot? |

| ->> Files that appear black in P.M. seem to be corrupt no matter what application I attempt to open them with. Again, the black frames appear when using the "ingest" option in P.M., when copying directly from a card, or even when viewing photos in folders on my desktop which I've previously worked with and I know there were no problems with that folder last week or two weeks ago or whenever it was that I last opened that folder. I just got off the phone with AppleCare & they were kinda stumped, too. |

->> It seems to me that the problem is in the Ingest function of PM. I've read on another message board that this happens with the Ingest function sometimes. I've not had this happen to me. I always use the Copy command. But it could be a memory problem when you use PM. don't get me worng, this is not a bash on PM, it's just that some people have had a few issues with the Ingest command.
I'd also check the scratch disk to make sure it's not full. Check the ram and make sure you don't have too many applications running at once. Do a clean install of PM.
Those are the only things I can think of. |

->> Hey Matt,
There was a discussion of this over on Lightstalkers. It has something to do with Photo Mechanic not being compatible with Mac's operating system. Apparently there is also a PhotoMechanic update, or a new version, that takes care of it.
Here's the link, maybe this will help:

->> Might be worthwhile buying another drive to put in the second bay and clone over your system to it. Try running from the new drive to see if the problems persist. It's possible your current boot drive is flaky and not being repaired properly (or something is breaking the repairs). Does Disk Warrior indicate any problems (red text) before you have it overwrite with the new directory?
Is there a particular reason you're sticking with 10.3.5 and haven't upgraded to 3.9 if you don't want to move to Tiger? |

| ->> I could be completely off here, but I had a similar problem on my PC. One stick of RAM had gone bad and was corrupting images when I would work on them. I ran a RAM test program and found the bad memory. No problems since then. |

| ->> I notice that sometimes my files become corrupt or truncated after I have transferred them from my laptop to my desktop via firewire. I start up my powerbook and hold down the "T" key to make it an external drive, then connect it to my desktop and then copy the files. Has anyone else noticed this? |

->> Thanks for the suggestions and advice on the message board and via email...I talked with Apple Care & ran the various tests & disk utilities and I *believe* the problem is bad RAM. Took out the offending chips and ran a few tests...Computer is running slower, but no black photos so far. At least one of the few things I'm fairly diligent about is backing up my stuff. What a scary feeling to see photos randomly disappearing. Who knows why RAM goes bad...Poor parenting?
As to why I don't upgrade to 10.4...well, lazy, cheap (funny, the money I spend on flying & I'm too cheap to do an OS upgrade...ah well.) and I've had bizarre bugs show up in the past when upgrading from various versions of 10.3, so I figure if 10.3.5 works well on my machine, don't mess with it. |
