Securely delete individual files from virtual drive on SAN

security storage-area-network

Given all the layers of abstraction between cipher.exe and the physical disk (guest file system, host file system, SAN, RAID, drive controller) I'm assuming the odds that the application will actually be able to overwrite the physical disk sectors containing the sensitive data are almost nil.

I'm not sure this assumption is easily provable.

If you are interested in a utility that is slightly more thorough, SysInternals SDelete is the only other Microsoft-provided utility that I am aware of.
