A fellow taper here is looking for a way to fix some files that didn't get closed properly, due to a power outage. Since it hasn't happened to me yet, I didn't know what to advise him to do...
A couple weekends ago I recorded an all day festival ...... Right after they ended their set and the stage announcer was saying thanks, goodnight etc... the power went out to the whole place because some idiot was flipping breakers trying to turn on lights to a parking lot. My DR-60D was still recording on AC and had batteries in it at the time. The power loss froze the deck and eventually I had to pull the batteries to turn it off.
Got home and checked the SD card which appeared ok until I realized I had everything but those two last WAV files.
And here's the weird part. There's 8gb worth of music totaled for the WAV files I can see but there's another 2.5gb of files that I can't see. so I think there still there but in some sort of limbo state.
Is there some sort of file-header repair utility, or SD card procedure to fix this? I know we're in the right place for some answers.....thanks y'all

Read the Data Recovery and Corrupt or 0 byte file
sections of http://taperssection.com/index.php?topic=117279.msg1567216#msg1567216 for possible methods of recovery (or writing a new header).
One tip: make a copy of the file and always work on the copy, NOT the original so if what you try doesn't work you still have a file to try a different fix on another copy of it.

Thanks :suds:

I am not sure what operating system you are using, but if using a *nix OS, you can use dd to clone the card before attempting any work on the files. That is my first step to recover accidentally deleted files, for instance. I am sure there is something under windows that will clone it if that option doesn't work for you.
One precaution so you can f'up and not stress out about it, just try again.
