My limited understanding of Windows storage Spaces in Mirror mode is that once something is deleted it is released back into the Pool & I would think that perhaps over-writing might in fact be over writing to a different location. A little how a SSD would work & that you never over-write the same location.
I believe that with Storage Spaces Windows even operates a TRIM like system to release locations. I guess not to reset in the same way an SSD is Trimed but does make me think that this is what happens.
I was also looking to a erase individual files or folders but CCCleaner does not seem to be able to do this.
I see Recuva does, not tried it yet. Is this effective & does the above apply re. Storage Spaces, with individual files.
Based on ten minutes ago I knew nothing about storage spaces, and five minutes ago I read a quick how-to guide...
From that guide: 'When you add a disk to a pool it's completely wiped and becomes inaccessible to Windows. You can't access it through the Explorer, nor save regular files onto it directly; and if you ever remove it from the pool it will need to be reformatted before you can reuse it.'
So I would guess that CC's secure file deletion would work, as that's an edit of a live file before it's deleted, so the edit (overwrite with zeroes) would take place on all copies of the file in the storage spaces.
WFS would not work, as it appears that the disks holding the storage spaces are not accessible via Windows.
Recuva file overwrite would not work, for the same reason.
In other words as Windows can only access the files in the storage spaces, and not the disks holding the SS, then only file-based operations are available.
If you're using SS then you can see if the SS disks are visible in Explorer with volume letters assigned. If not, and I guess that's the most likely, then you can't run CC's WFS or Recuva against them.
Thanks for that, I only recently got interested in storage spaces as seems to be a better type of protection against HD failure, even than BIOS raid.
You only see the ONE pooled driver letter & not each individual disk.
I did find this below, that BCWIpe advertises. I think they are more promoting that it does not need to wipe the WHOLE drive but does imply that it knows where the data is and is able to clean it.
With ref. the file deleting. I have never used the CCleaner option as 99% of time would want normal delete so would have to go into the settings each time when I did want secure delete.
Am I missing something or is there a quicker way, No great hardship I know but I generally use software that has a right click on normal explorer.
Wipe selected files and free space on Windows 8 Storage Spaces
In addition to the ability to securely erase files, BCWipe offers a convenient solution to Wipe Free Space on Storage Spaces. Once the command is launched, BCWipe reads the disk configuration and analyzes Windows in order to exclude from the wiping process all unallocated space (or the unused portion of free space). BCWipe now only needs to run on the allocated free space, which may contain sensitive information.
