I'm afraid you're going to find my answers pretty useless.  To wit -

I wouldn't know.  I've never taken one apart.  They come in enclosures
obviously and well designed to disourage tampering.  I will, however,
observe that the available drives have always been of far smaller
capacity than I'd expect and their new drive introductions seem to come
quite slowly.

attacks and other attacks are possible.

these drives.  You couldn't get to the components quickly enough or
without damage.

Sorry, no, I can't.  My experience was initially with a stand-alone
application (a prototype system for transporting evidence) for which any
sort of centralized management (or even a network connection, for that
matter) would not be allowed.  Stonewood did provide a download (I can
no longer find it on their site) with various management scenarios when
passwords were forgotten.  They centered around bringing the drive back
to the security function who would type in a recovery password.  The
notion of "centralized management" to me conjures up scenes of forgetful
users calling a help desk and getting a drive unlocked; that's not the
way these things work if I understand them correctly.  Keep in mind that
my experience has been with just a handful of drives, all intended for
use in a disconnected environment where "management issues" are of no
concern at all.

>What about password recovery?

It's relatively straightforward, even if the docs that come with the
drives are not written as clearly and consistently as I'd like to see.
Two passwords are set in the beginning.  If the user forgets, the drive
can be unlocked by the admin who types in their password.  Very basic,
very hands-on, and exactly what I needed when I bought my first one.

BTW - The prototype that I put together with the first of these drives
was shot down by my management.  An all-software solution was adopted.
Since then, I've purchased from Stonewood only for home use.  Thus, I'm
probably not the best person to ask about the product in a large,
centrally-managed environment since I have no experience with that.
However, I hope I've provided you some useful info.

One last thing - While I assume and sincerely hope that the situation
has changed for the better, some years ago when I first made a purchase
I found the North American resellers to be a dismal lot, essentially
unable to find their own backsides with both hands.  Stonewood obviously
encouraged me to deal with them but I eventually had had enough with
unanswered emails, emails that spouted marketing nonsense in response to
technical questions, and phone calls from salesmen reading from scripts
who seemed to have absolutely no knowledge what they were selling.  I
complained directly to Stonewood that I couldn't do business with them
and Stonewood then dealt directly with me.  That surprised me; I had
originally found Stonewood by poking around in the .mil domain for RFPs
for encryption so I assumed they were accustomed to dealing exclusively
with big orders from military and government types.  I need not have
worried.  Despite the fact that I was merely buying a single drive here
and there, they were willing to treat me like a valued customer.  I
found every person at Stonewood with whom I had contact to be highly
professional, competent, courteous, and helpful.  Dealing with them was
an unalloyed joy.
