Can't view files on my WD HD that showed before

i am running MAC OS X 10.6.6 on my macmini… i had previously owned a mac book which i transferred all my photos and music onto my WD HD. Before on my macbook, when i opened my HD it would show me the folders in which i transferred but nothing in them. when i bought my mac mini and connect my WD HD it showed me all my files in all my folders. 

now it seems like i am back at square one. when i access my WD HD it shows me all my folders and about 90% of my files, with certain picture folders empty again! = (

at this very moment… my WD HD front vertical LED light is bouncing up and down like a pogo stick… 

can someone please help me???

thanks!

Lights bounceing up and down? Is it pssible that you post the model number of the WD HD it would greatly be appreciated :slight_smile:

MDL:WD10000H1Q-00   would that be it? 

I see you have the My book studio edition

The lights moving up and down mean that the drive is currently in use take a look

thanks! now i know the lights are not an issue.

how would i be able to view those files in that one particular folder that used to show before? i have went to Disk Utility and repair disk… and everything is still the same… 

any suggestions? appreciate your help!
