PSD Corrupts While Open in Lightroom

My wife is running LR3.6 on OSX 10.7 and edits in CS5. The Lightroom catalog file resides locally on her MacBook Pro and the PSD is on a network share. The share is on a Mac mini server running 10.7 Server. The share is on a direct attached Drobo S. Drobo Dashboard reports the drive array as healthy. I sent a diag file to Drobo, and they confirm the drive is functioning normally. Further, I ran Disk Utility Verify Disk on the drive as well as the partition, and both checked out OK.

What we have been seeing is two fold. When we import NEF files from her D3S, we see an occasional file with random color banding across the pictures. The second issue is sometimes a PSD file will all of a sudden develop a random colored line across the image. Here is a link to the corrupt PSD file http://c.tro.pe/IGb7 and this is a link to a screenshot of the bad NEF import http://c.tro.pe/IGzj.

She will see the PSD open in LR and the line will show up. Perhaps this is LR updating itself based on what it sees on disk. Has anyone else experienced these issues? Thanks!

Likely bad hard drive or memory stick in the computer.

Which hard drive? Drobo, server or MacBook?

Check your RAM. I know on PC that there are free, bootable, standalone memory testing programs that can be found on the web. There must be something similar for the Mac, maybe even supplied by Apple.

At any rate, you are seeing classic symptoms of some kind of hardware problem. Since it happens after import, the problem is, as Lee Jay says, in your disk drives or memory. Since your image is on the Drobo, that would be the drive to suspect. I don't know how good the Drobo diagnostics are, but you could try keeping your images on a different drive for a while to see if the problem continues. If it does, then the problem would likely reside in RAM.

Good luck. Intemittent hardware problems are hard to troubleshoot.

OK. New info. My wife was using Lightroom and had a PSD file open. She clicked on the Temperture button one click towards the yellow, and the line showed up. As it turns out, this is the same thing that happened the last time. I was unaware that there was a step she took before the corruption occured. I tried to click back to the prior step in the develop mode history, but the line remains. What could this be? Thanks!
