Diskeeper 2016 is definitely Better Than Version 2011 was.

Both mentioned versions of Diskeeper have approximately the same features, including to perform ‘Fragmentation-Prevention’, by caching files that are being written to the HD for longer than Windows would normally do so, in order to be able to write contiguous output blocks, and including ‘Background-Defragmentation’, for which we can schedule times of day or days of the week we want it to happen.

One fact I find odd under Windows, is that no effort is made where the user can see it, to distinguish between ‘Fragmentation’, and ‘FS Corruption’, the latter of which can also be called ‘File System Inconsistencies’. The idea in the minds of Windows software developers seems to be, that whatever we have, we have, that being, whatever is linked.

But a deeper fact which I know about Windows, is that if an efficient defragmenter is let loose on the File System, and it encounters actual FS Corruption, it will cause Windows systems to crash – to do one of those nasty reboots which the user did not tell them to do. This has led to some people not being able to get through a defrag, before the computer would crash, until those users ran a File-System Check, between reboots, using ‘Checkdisk’, which solved their problem for them.

When either version of Diskeeper is told to do a manual defragmentation, it does not go as deep, as one of its scheduled, Background Defragmentations go. This was a major reason for My Previous Posting.

What I have learned, is that the 2016 version of Diskeeper, does a much more thorough job of cleaning up the File System, even during the Background Defragmentation, which its software company no longer touts as a major feature. The software company mainly touts the Fragmentation Elimination feature. But BG-defrag having taken place successfully last night, and having produced the report it did, makes me confident again, that it was able to find FS Corruption which neither its 2011 version, nor Windows Checkdisk, were able to recognize. And so I may be able to keep the present O/S installation on ‘Mithral’.

In fact, having been able to perform heavy computation continuously from 13h00 yesterday, until 4h00 this morning, while Diskeeper 2016 was installed, and then allowing this software to do a BG-defrag, also impressed me about the idea, that at least the H/W seems to be quite stable.

(Edit : ) It would not be obvious how “Fragmentation-Prevention”, would reclaim those 13,184 blocks. But according to the System Software I studied, there is an answer. There exists Internal Fragmentation, and External Fragmentation.

When we tell Diskeeper 2016 to perform a Manual Defrag, we have two buttons to click: Optimize, or Reclaim… So we then have a choice, on whether to focus on the Internal or the External Fragmentation, the latter of which exists between the allocated file-fragments.

Well, when Diskeeper is doing its Background-Defragmenting, it is going deeper, and doing both.
