I am installing Win 7 x64 on a new HDD. about 5 minutes into the install I get Error 0x80070750 file or directory corrupted and unreadable. It's a new Win 7 DVD, it's a new 1.5 TB HDD partitioned C=498GB, D=909GB. I have tried a new HDD with the same config, and a second Win 7 DVD. This keeps coming up, usually at or about the same time in. All I've seen so far about this has to do with existing Win 7 installs, not a new one. Anyone have any ideas?
