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>
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
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!
