Anyone with data recovery wizard skills?

Edit: Well here's a sneaky preview of one of the many jet/prop plane recordings I managed to save! ;)

http://soundcloud.com/andrewjohnlewis/jet-preview

Just spent the whole day at an Air Show. Had a Nagra LB and a Sennhesier 418 (hired). Got loads of great sounds. Spitfires, various jets etc. Sounded cool when I checked the files over my headphones while I was there.

So got home all excited. Attached the USB cable to my Mac and connected the Nagra. Thought I'd see a whole host of Wav files come up, but instead saw jibberish. Turned back on the Nagra to check again and now it wont access the files!! Says Database Sync Error. It seems to quickly flick through the list of files I recorded but doesnt let me play them, as it previously let me. Really, really annoyed.

Anyone have a clue how to recover or save data from a Compact Flash card? Was a Sandisk Extreme if thats of any use :(

Edit

Thanks for all the suggestions guys! Managed to save almost all of it with the help of Sandisk RescuePro. Very useful little proggy!

I'd switch to command line rather than relying on the Finder (I take it you're using a Mac because you're into sound, it's only a guess from personal statistics, I'm not categorizing or anything).

Use your terminal, navigate to /Volumes/ using

cd /Volumes/<disk name>

Type ls and press enter (it's short for list, it'll list the files it finds in the directory you're currently in, normally <disk name>) and hopefully you'll see something, maybe not a file list, but at least you'll manage to read bytes. I'd then try several manipulations:

In the case you see files, type:

Do the following:

mkdir ~/Desktop/save/ #this will create a folder named `save` on your desktop    
mv * ~/Desktop/save/ #this will move all the files it finds in the current directory to the `save` directory you just created on your desktop

In the case you don't see any file, I'm not quite sure what it'd look like, so I'd suggest you create an image of your flash card using Disk Utility (select your drive in the column on the left hand side and hit New Image in the tool bar at the top I believe) and send it someone's/my way if you're comfortable with this. Someone/I can have a look and hopefully find the problem/solution.

Alternatively, use Disk Utility to find the ID of your device: in the left hand side column click the disk (not the partition inside it, but the disk itself) and click Info in the toolbar at the top. The Disk Identifier looks something like disk1.

Then, in your terminal, type:

dd if=/dev/<disk ID> of=~/Desktop/save.img #this copies the byte sequence of the drive, it effectively makes a backup of it.

Maybe I haven't got my head round the issue just yet, so please don't hesitate to pick my brain if you think you might make progress with a little push.

Hope it helps and you get everything back!

I've had luck running TechTools on drives, although I've never tried it on an SD card. Principle should be the same though.

This worked for me. It can get from easy and quick to advanced and slow very quickly.

Don't do anything else to the card, something has been overwritten in the table of contents TOC, the data is probably still there.

The free version of Sandisk's RescuePro will tell you if the files can be recovered.

If it works the license is £30 for one year.

If it doesn't work there is a form to contact San Disk for further solutions.

If you can try, using a compact flash card reader connected directly to your computer to remove the variable of the recorder.
