Hi, My sister has a Sony VAIO VPCF115FM laptop with a Seagate Momentus 5400.6 SATA 3Gb/s 500 GB ST9500325AS hard drive and Windows 7. I was going to replace the hard drive with a WD Scorpio Black WD5000BPKT. I put the WD drive in an external enclosure and connected it to the laptop through eSATA. I cloned the Seagate drive to the WD drive using Acronis True Image WD Edition (free from WD and takes in to account the Advanced Format Drive) and everything seemed to copy over OK. However, after I removed the Seagate drive and replaced it with the WD drive the problems began. Windows started up normally, found a driver for WD hard drive, then insisted on a reboot. After the reboot the UAC was acting up. Note: I did not change any UAC settings. Now all Microsoft programs that were previously cleared and didn't prompt for allowing changes- now they prompt to allow. For example: right-click Computer and select Manage. Previously it would open the next window without any prompts from UAC to allow and it showed the publisher as being Microsoft. Now UAC prompts to allow changes and it shows the publisher as Unknown. Everything in the Control Panel with the little UAC shield by its link now prompts to allow access when previously it didn't. I could switch off UAC all together but I'd rather not. Doing that would only cover up the problem and this is my sister's laptop. Certain services aren't working properly. Windows Update no longer works. If I click on Check For Updates it just shows a red shield with an X on it and states that the Windows Update Service isn't active or working or something like that and suggests a reboot. A reboot doesn't fix it. Also, in Event Viewer I'm seeing errors stating that the Search service failed to start. I am guessing there are other problems that I haven't discovered yet. It seems to be that something isn't working right in Win 7 as a result of Windows being cloned and moved to a different hard drive. Should I give up on using Acronis True Image WD Edition to clone the drive and try using the Win 7 built-in disk image backup system instead? I thought that using Acronis' software would be easier to use but that appears to not be the case. Any ideas as to what broke in Win 7 and how to fix it?
