HD-CE500U2 - DRIVE SHOWS BUT CANT SEE FOLDERS IN EXPLORER

[timonize]

   

I am using Buffalo external hard disk ( model HD-CE500U2) .  The firmware version is unknown.  I use it on a lenovo T400 or a Dell Lat 630. Both have windows 7.  One day i could not see the folders anymore.  It still recognizes the drive.  I have used about 250 gigs on it ....and it still recognizes that space as being used.  I can even add new folders to the drive.  Just cant see the old folders anymore.  I can see the drive in disk management as well (FAT32 Health Primary partition).  When i click on the drive in explorer ...all i see is "n" which is a system file and thats it ...please help !!!!

Unfortunately it sounds like a classic case of data corruption.  I would suggest exploring data recovery (if necessary) and the formatting the unit afterwards.
