It is a shame but might be true.
I have been using a powerful Tower-PC named ‘Mithral’, on which I have installed Windows 7 Pro, and which has an 8-core CPU, threaded as 4. This computer was first installed in 2011.
This computer had special software installed, named “Diskeeper 2011″, which continuously defragmented my Hard Drive, but in an effort to be able to save the HD even in the worst-case Fragmentation / FS Corruption scenarios.
‘Mithral’ has developed the habit now, of repeatedly going into an unresponsive state, overnight, which is also the time when it has been configured to do its background defragmentation.
The fact that it never freezes during the day, but often now, overnight, suggests that the problem may lie in File System Corruption, which can lead to fatal errors, if defragmentation encounters it under Windows. I have run a ‘Check-Disk’ on it, but doing so has not remedied the problem.
However, one apsect of this problem which puzzles me, is the fact that so many defragmentations have run successfully, without immediately tripping over any FS-Corruption issues. This casts doubt on the idea, that the problem may be due to FS Corruption. What could also be happening, is that Diskeeper 2011 may no longer really have been compatible with the most-currently updated Windows 7.
And so, because these hangups seemed to be taking place during a time when Diskeeper 2011 was running, what I have done for now, is to uninstall that, and to install the most up-to-date version, that being “Diskeeper 2016″. As usual, I am able to tell Diskeeper to defragment the whole HD without any immediate errors. But now I will have to wait and see, whether continuous background-defragmentation, using version 2016 of the software, is ultimately more stable.
Because a computer which crashes every second night is not really supportable, I might eventually need to wipe ‘Mithral’, and to make an attempt to resurrect it, using some version of Linux. If I succeed, at least I will still have the benefit of the hardware.
There is some chance, however slight, that the problem is not really FS Corruption, but some sort of Hardware problem. If that should turn out to be the case, then even with Linux on it, this computer will still crash and/or be unstable. This will be even more sad.
To prepare for eventually reinstalling, I will need to migrate critical data off it, to my other computers, with a depth I have not had to do so in before. This will not be one of those cases, where I can just wipe the HD and kick the present O/S off it on a whim. I need to think this through, as far as data is concerned.
This is my last remaining Windows computer. There exist certain services under Windows, that I cannot duplicate under Linux, and I might need to get by without those.
