four things you need to try:
1. try to get a POWERED sata adapter! ($15 on ebay)
2. if that way can not work, use linux computer if you have.
3. use winhex to recover.
4. if nothing above works... last resort, put this in a ziplock bag, squeeze
out the air, put into freezer. wait 15 minutes and use it again...
No 4 always works for the first time and only the first time. It is the last
time you see the hard drive either...
