If the drive won't come on, freezing won't do anything cept make it a cold brick. I've only had the freezing issue work for a death tap where the spindle arms weren't working right.
What drive is it? Is it SMART enabled?
If you feel comfortable, you may try and find the same hard drive off ebay and do replace the PCB. I've done it twice (sucessful twice) and for $30 it allowed me to get the data off and onto an external drive.
