Hi guys,
Thanks Slugs, I have the source material. Unfortunately its all on DVD and needs ripping again. Boo.
The freezing technique looks interesting, however, there is no power to the drive. The company I sent it to reckon that the heads have gone. I am going to try another company soon. Thanks for your offers of money. Not sure what to do about that yet.
By the way the drive is a Seagate Barracude 7200.10, 250 Gbytes.
I wonder if I could track down another of the same model and get someone to weave some magic.
