On Suns the size field of a directory is a multiple of 512 bytes. And the minimum number of links on a directory is 2. These directories fufill these requirements and I think that they are really directories. But, on unix, directories are files and you can read them if you have read permission. One program that reads directories is called "ls". But you can use other programs too. I suggest "od -c".

Have you looked inside these directories to see if your files are there?

When fsck finds a problem, I always rerun it to see if I get a clean result. Every now and then, a second fsck run finds additional errors. You might try that.
