Secondary Internal Drive - each file reads Zero KB

Hi there,
Any help is more than appreciated. I am running a G4 and have a secondary internal drive for storage. Suddenly one day almost every file on it shows a file size of zero KB. The icons are correct, they show the correct creation software, etc. but if I attempt to open any of the zero KB files (and this is probably 95% or more of the files on the drive) they will not open or messages about no information in the file. Here's the kicker, the 40 gig drive still reads as 24 gigs full (or whatever the amount is) with 16 gigs free - so I believe the data is still there.
Is there any hope of fixing this?


thanks,
engeee

 

tried all of the above....

no luck at all...open for more ideas. Bring 'em on, there's too much data on that drive that I need.

thanks.
