      1. When you Install the downloaded full setup PD 12.5 Pro, the setup shows Perfectdisk 12.5 Professional. But when you start the trial, the title shows Perfectdisk 12.5, but not Perfectdisk 12.5 Professional.
        The msi-Package shows also Perfectdisk 12.5 Professional.
        The installed PD Pro is a PD Home Premium.

  1. Hi — We installed both PD 12.5 Pro and PD12.5 Home Premium. In the title bar for each – it says PerfectDisk Trial – just as it did before. With Pro installed, the Dashboard and Smart tabs are available – which is correct. With Home installed, the Dashboard and Smart tabs are NOT available – which is correct.

    Are you seeing something different?


    1. Ok, with home installed, the smart tab and dashboard are not visible.
      With Pro installed (x64!!) these tabs are available. Then it must be the business version?!

      When you install the PD 12.5 Pro full setup build 309, it shows Professional in the titlebar.
      After this you install the msp-patch build 312, the titlebar shows also professional.
      But when you install 12.5 Pro full setup build 312, the “Professional” is not in the titlebar.
      The smart and dashboard tabs are in the three builds/installs available.

  2. Pd 12.5 B 312 Trial will not defragment the hiberfil.sys. The checkbox to disable the defragmentation of it, is unchecked. So it must theoretically defragment. but it doesent (Windows 8, x64)
    The log says:

    121010-17:45:47.88 DefragFs: IRP_MJ_CREATE: ‘Hiberfil.sys’, DesiredAccess = 0x00100080.
    121010-17:45:47.91 DefragFs: Created Fcb = 0xFFFFF8A00016BEB0, Name = HIBERFIL.SYS.
    121010-17:45:47.96 DefragFs: HiberFil.sys open intercepted.
    121010-17:45:48.33 DefragFs: IRP_MJ_CREATE: ”, DesiredAccess = 0x00100001.
    121010-17:45:48.34 PDBoot: Hiberfil.sys id = 48

  3. Your products for PerfectDisk list a “Home Premium” and “Pro”. But your trial downloads list “Pro (home)” and “Pro (business)” I am starting a download from the “Pro (home)” link but the file name is “PD12.5_Pro.exe”. Can you clarify please?

    1. Pro (Home) is the PerfectDisk Pro product on the home user side. Pro (Business) is the business version, which is networkable (for compamies that want to centrally manage multiple PCs). There is no download link on the blog for Home Premium. Home Premium doesn’t have the Space Management features of PerfectDisk Pro. If you want to try PerfectDisk Home Premium, you can download it here:

    2. Hi Paul, there is a Home Premium available under the Home section, but there is also a Pro version under the Home section. The Home are Business Pro versions are basically the same product (feature-wise); they just have different licensing models. Sorry for the confusion…thanks.

  4. I know PerfectDisk supports traditional hard drives, and SSD, where SSD’s have very different needs. But, what about hybrid? I’ve got one of those Seagate notebook hybrid drives. 750 GB hard disk, and what, 32 GB SSD, something like that. How does PerfectDisk handle that?

    1. Hi Paul,

      What makes a drive a hybrid is that there is a traditional HDD component to the drive as well as a large amount of flash memory. Flash memory is used to cache frequently read/written data. However, all data is eventually stored on the HDD component of the drive – it is cached on the flash memory component as determined by the drive controller.

      Windows doesn’t know that a drive is a hybrid – so PD doesn’t know. All Windows knows is that the drive is formatted as FATx/NTFS and that is all PD sees as well, and will defragment it as such.
