indeed a nice comparison rchadwick

and I fully agree everyone having all keys of prisondoors or banks or safes or even the 'red button' etc etc wouldn't be a good idea.
But I guess not all locksmiths do have keys of those 'doors'
But the comparison doesn't address the issue why utilities for resetting (or finding) passwords like the one I mentioned are so much different from a legal point of view and THUS why a utility to unlock a HDD is so much different from those utilities.
In fact , if you are ONLY able to erase the HDD instead of unlocking it (and preserving the data) those utilities out there to reset administrator passwords making it possible to login again and accessing the data are much more dangerous as by nature they DO keep the data.
We all know good algorithms exist to encrypt data.
So IF data on a harddisk are sensitive they should be encrypted. If so, harddisk protection by a password will not be necessary and just a way of limiting access.
In fact as some people (the 'locksmiths') do have knowledge and tools to remove protection of the disk this protection is far less secure compared to encryption and should NOT be used for sensitive data.
On the other hand I suppose most data aren't REALLY sensitive or secret but 'we just don't want everybody to be able to have easy access to them'. For such data a HDDpassword will be a useful protection instead of encrypting the whole disk (or part of it). If a HDD gets locked unlocking it would be a useful utility. Also, if data are sensitive/secret a good backup procedure must (and most probably 'will') be used. Within a business or government it will not be a problem to replace and destroy a HDD if i gets locked, but if a private person just locks the harddisk to prevent 'others at the house' to have easy access to it or it gets locked for one reason or another, the HDD would most probably still be used if being able to unlock (with or without the data being preserved).
so:
a) do you agree encryption of data being much more secure instead of a HDDpassword as some unauthorized 'locksmiths' may get access to the data?
b) do you agree utilities to reset administrator password are as least as 'dangerous' but don't suffer from legal things?
c) do you agree professional organisations will (or should) have good backup procedures and shouldn't rely on 'locksmiths' to unlock a disk?
d) private people will benifit much if a free HDD-unlock utility would exist as now they will throw away the harddisk and buy a new one most of the time (extra polution as well! Also a chance it will get into the hands of someone who can get access and get some data of it that are sensitive [like bankinfo or certain personal information]) instead of consulting a professional?
