Importing Session into Catalog Corrupts RAW (Sony ARW) File
Luckily, I backed up a copy of my session ($30,000 job!). BUT-
I've copied said session to my NAS. Then, when I import the images (not using the "Import sessions") to my catalog on my workstation, leaving the RAW file on my NAS, it seems to corrupt the file to where I get lines (horizontal or vertical) of varying thickness, mostly black, but some with hairline colors through my images. This is totally random. Also, my ratings (stars) are gone. They appear this way in finder, when I open them in photoshop, no matter what. The really curious thing is, I'll put the seemingly corrupt files on a flash drive and open them in photoshop, preview or CO on another computer, and they're fine. Any ideas?
This image is directly processed from one of the corrupt raw files:

Note: These lines are slanted due to some perspective correction being applied.

What you're seeing is never actually the RAW file but the preview generated from it.
Are you sure it's not the preview itself that got corrupted? Try to recreate it.
Also, maybe you could md5 one of your RAW file and its backed up version, just to be sure.
Do they appear corrupted in OS X's Finder too?0 -
Thanks so much for your reply!
I've tried recreating previews to no effect. I've deleted the catalog and the copied session, created a new catalog and re-imported a newly copied session, and the lines show up randomly on other files. Also, my file ratings don't show up. Another observation is, the star ratings show up on the previews, and the previews start out clean, but partway through the import, it all goes awry.
The thumbnail and quick preview of the actual RAW file shows the same lines (without any corrections from the xmp file, of course) in finder. BUT, if I connect to the same folder, through the network via another computer, there are no lines. It's as though it's something that gets appended to the file when the import into the catalog takes place, that only my workstation sees. The other curious thing is that it clearly shows up on processed files.
I'm sorry, but I'm not sure what you mean by "md5".
I'd love to get catalogs working With my NAS through my network. Up until now, I've only been shooting to sessions and archiving. This is the first time I've tried after watching Mr. Grover's webinar, and I'm failing miserably.
I wonder if it has to do with the way my Lenovo NAS communicates. Hmmmm.0 -
About md5:
Open a Terminal, type "md5 " (without quotes) and drag&drop your RAW file from the Finder to the end of this line. Press the return key. After a while you'll get a long number, which is the md5 signature for this RAW file.
Do the same with the backed up version of this same RAW file.
If the numbers are different, then one of the two files is most certainly corrupted (or as you say there's something wrong in the way your Mac reads the files stored on your NAS). If they're the same, then the two files are identical.
When you say "BUT, if I connect to the same folder, through the network via another computer, there are no lines", it gives me good hope that the files are indeed OK.0
