IMPORTANT WARNING about System C:\System Volume Information.
If you need VSS for partition image backups etc. you MAY encounter difficulties if you prohibit "System Volume Information" from partition C:\
Very recently I have seen on the Macrium Reflect forums, and elsewhere,
that VSS places system snapshots in "System Volume Information".
I understand from Macrium that when I make a Macrium partition image of a partition then VSS snapshots are placed in the "System Volume Information" of that partition.
That is NOT my experience.
Before I was aware of VSS I used my technique to absolutely prohibit "System Volume Information" from any non-system partition,
and yet Macrium still created good restore-able image backups of non-system partitions.
It seems plausible that the first choice for a VSS snapshot MIGHT be in the "System Volume Information" of the relevant partition,
but it obviously is able to find an alternative location.
It may well be that VSS snapshots may be all held in "C:System Volume Information".
Please not that originally I was unaware of such repercussions.
My sole concern was that non-system NTFS partitions on a USB2 external drive caused pain and grief.
If I right clicked on a 100 MB file with a desire to inspect its properties,
Windows XP would make me wait for perhaps one or more minutes whilst it COPIED that file into a Restore Point on the same partition,
and only after completing that duplication would it open up the context menu to choose "properties",
I suppose XP is so feeble minded that it assumed I would choose "Delete" and that it would not be fast enough to intercept the action and delay until it had actually backup up into the restore point.
I was able to disable monitoring of all external drive partitions,
BUT
I could only disable drive letters, and sometimes a power-up race hazard resulted in partitions getting DIFFERENT drive letters which defaulted to MONITORING.
Hence I developed the technique to permanently block "System Volume Information" on all such partitions.
I have never blocked "System Volume Information" on System C:\ because it never caused me grief.
I will be interested in hearing if the warnings I have seen are actually justified.
I also wonder where chkdsk.log files will appear if "System Volume Information" is prohibited.
N.B.
I am able to learn from my own mistakes,
but life is sweeter if I can learn from yours
