I have Windows 2008 R2 box on colocation. I want to remove certain files with a high degree guarantee it cannot be recovered from physical HDD access.
Could someone please explain what levels of security (NTFS-wise) can be achieved with different tools?
Please note I have RDP into this computer and plane IPMI - I can reboot it safely even if OS is frozen
Also a side note - by physicall access I mean that there are bunch of commercial labs who does fairly good job recovering data from damaged disks (even with damaged margnetic plates) - so I'd like this to be covered.. However I understand that technology available to such labs is not the same as say specialised government agencies (these I dont want to cover).
