Help to recover data

Hello,

My laptop went out of order. I used integral external enclosure to recover the data from the laptop's hard drive. I followed all the insturctions of the manual. The problem is when I enter to the enclosure drive through 'My Computer', I find two folders, one is Recovery other one is OS. When I check all the files of the Recovery folder, to my horror, I find all the files are empty. Have I lost my data? Please help me to recover my data. Thanks a lot.
