Repair corrupted CS5 psd file?

[MBX]

Basically what happened, a very good friend of mine worked on a CS5 psd file and worked directly off of dropbox. He said he never had any problems doing that instead of working locally but this time it seems to have corrupted the file.

I'm trying to help the poor sob and see if there's any chance to retrieve the data.

Anybody know if it's possible somehow to repair a corrupted CS5 psd file?

I have googled everything possible and tried some few apps but it didn't work. Most of these psd-repair apps are for windows so i did it via parallels and while the apps said it was successfully repaired it didn't repair it at all but create hundreds of individual empty psd files. I assume this is because these repair apps still haven't been updated to read CS5 properly.

And any CS5 program and any other image editing/ preview apps refuse to open the file.

And the file size is still the same as it was in healthy state (around 250mb) so it seems it did keep the data but somehow must have corrupted it.

Is there hope or is it all gone?

Usually you'd have temporary psd files when working on local drive but he was working off of dropbox.

I've had this happen to me many times. Sorry, but that file is gone. Now I save my files on separate drives and work off my boot drive always.

If your file was hosted on dropbox, there is a chance that dropbox might have a backup of the file before it became corrupt. You might want to look into dropbox's history and see if you can find an older version.

This also stresses the importance of having backups. If you have a local timemachine (or other backup) you can retrieve the file the day before it went bad and work off of it.

I'm not positive on this, but I think when you log in on the Dropbox site, there is a drop down box next to your PSD files. Click that and then click "Previous Versions." I believe it might be in there.

Hope that helps.
