Hi Everyone, I have an imac. I tried to install windows 7 from boot camp and the WEI for disk drive (SSD) was 7.9 Then I decided to remove mac OS and make it completely windows. So, again using the boot camp I re installed windows. But this time I deleted the mac OS partition. Windows installed without any problems, but the WEI score for disk drive dropped to 5.9 I tried installing the latest AHCI drivers and used the disk cleanup utility to remove 400 MB of junk. Now I run the WEI again, and the disk drive scored 6.3 Since the ssd scored 7.9, I'm confident that there is some wrong setting that I need to fix. I'm attaching the results of my winsat disk and as-ssd benchmark tests. Since this is an imac, I cannot access the BIOS settings. and I'm running out of options. Any help would be appreciated.
