I have a Dell computer that had a 500 gig HD in it. The computer would not run the file transfer program nor would it run Windows Installer (among other issues). Well, I had figured on buying a new HD, keep the original drive "as-is" and just install Windows7 (Home Premium -- 64 bit) on the new HD from the Dell OS disk. Then my friend suggested buying 2 more Hard Drives and a RAID controller card and set up the "new" computer in RAID 5. (I needed the RAID controller card because the Dell wouldn't support RAID 5). The RAID installation went fine (though no performance difference at all when running the Windows 7 Experience Index). The installation and updating of Windows 7 went smoothly and uneventfully. My problem is that when I run the file transfer program, it wants me to put the old hard drive (which I have attached to the new computer via an external hard drive case) back in the "old" computer so it can run the transfer program. However, the "old" computer is really my "new" computer and I can't figure out how to get the darned thing to run. Any suggestions would be greatly appreciated. Thanks!!
