My experience recently I was very happy to be contacted by a Parallels support person (named Andrew) who asked for my number and shortly after phoned. We went through the most recent of the three totally different approaches to solving my .hdd file problem. When we reached the point that it said my .hdd file was "corrupted," the phone connection broke off. I have not heard from Andrew again--this was last week. At the time that Andrew called, I had a Windows XP VM that was working (although with no programs or data installed) and, as a result of trying to get Parallels to work properly, at least three and perhaps four VMs with "corrupted" .hdd files. Something we did during the phone conversation caused the working Windows XP VM to lose Windows completely. It now wants to "boot from hard drive" and nothing I do causes any response at all. I asked Parallels support via e-mail if they thought my situation is hopeless. IF they do, I would like to eliminate every trace of Parallels from my iMac and then re-install Parallels 3 from scratch (updating to the latest build). So far, no reply.
