Have an external drive that cannot see all the files

Have an external drive that was formatted in FAT 32 then MAC files were saved to it.   There was a problem with some of the files so the owner ran chkdsk on the drive now only half the files can be seen or accounted for.  There was almost 350 GB of files but now you can only see about 196 GB.   Is there any way that those files are still on the drive or would you say they have been deleted?

I don't know MAC but amn trying to see the files with the external plugged into a PC

A PC might not see Mac files if the file names contain illegal characters.

Try GetDataBack http://www.runtime.org/  There's a version for FAT filesystems there.  Free to try.  If it sees the missing files you pay for full functionality.

Also look at PCInspector http://www.pcinspector.de/file_recovery/UK/welcome.htm and Recuva http://www.recuva.com/

Both are free.

I'd try GetDataBack.  If it sees your files then try the free ones.  If they work you save money.
