I checked this out once – only found two places which were able to provide the service.
A couple of years ago, the cheaper of the two places was starting at around HK$10K upwards for complete recovery… think they charged HK$2K to just have a look and quote based on what they found.
At that time I searched the net to find those couple of suppliers
If it is super important I could call my computer friend tomorrow and ask him for some recommendations.
PM me if you would like me to do that.
