I received the following email from Raxco this morning:
Raxco is proud to announce that PerfectDisk 8 is the first and only defragmenter to be Certified for Windows Vista by Microsoft. PerfectDisk 8 Build 50 is now available for use on Windows Vista, as well as Windows XP Home/Professional, Windows Server 2003 and Windows 2000 Professional/Server.
During the PerfectDisk 8 Vista certification testing process, Raxco's development team uncovered a bug within a component of Windows Vista that could potentially cause hard drive corruption. Raxco has already reported this bug to Microsoft and Microsoft is working to resolve the issue. Raxco has designed PerfectDisk 8 build 50 to specifically work around this issue.
I thought diskeeper 2007 supported vista? meh lol
It may support it but not be certified, I suppose?
