[comp.binaries.ibm.pc.d] locking out a hard disk

datta@vacs.uwp.wisc.edu (David Datta) (09/21/89)

I am in the position of putting a machine with a hard disk out in a
public area. We do not want to give most people access to the hard
disk.

Previously, to keep users from using hard disks, the folks here just
made sure that the hard drive used DOS 3.3 and the only floppy versions
they made available to others were DOS 2.10. I do not feel this is a
good way of accomplishing the task. 

I am looking for a way to lock out a hard disk to prevent any
unauthorized access through software or hardware. 

The software needs to be able to prevent someone from just coming in
and booting up on a floppy version of DOS and then letting them have
access. Are there any such packages, available commercial or
otherwise?

The hardware is a Flashcard 20Mb, I don't think there is a way to put a
hardware switch on it but this is an option if it is possible.

Thanks for any help in advance.

Since you have a hard disk card, perhaps you could put in ANOTHER
hard disk controller, and set it up to CONFLICT with the addresses used
by your hardcard.  Then put in a switch to enable/disable it (or
remap its addresses).

If you change your floppy station so it would be drive B: in stead of A:
people could only boot from harddisk. DOS would look for (a floppy in) A:
not find one and go on with C: .
When the PC crashes sometime you have to take the trouble to change the
hardware again to make your floppy drive A: so you can boot from it.

BTW:
It would be safer to take out your floppy station completely :-)

The solution that you are looking for is: PC-Lock which can be
had from Johnson Computer Systems, 20 Dinwiddie Place, 
Newport News, VA 23602.

It will do all you ask and alot more.  It is about $30-$50 as
I remember.  If someone does not have the password they can forget
about getting at the hard drive even if they pop the cover.

Another solution to the 'hard-disk with sensitive information in a
public access area' is to use removable hard-drives such as the
Tandon Ad-PAC.  Available in 20, 30, and 40 Mb (soon to have 80's
and 100's last I heard).  The drive is removed at the end of the
work period and stored in a vault.
 
Lets face it, if someone wants the data off of your hard-disk, and
they have unsupervised and uninterupted access to the machine, that
data is as good as gone.  If I can do, someone else can, too.

manufacturers do indeed make equivalent products, but I am more
familiar with the Tandon product line.  I am also a satisfied user.
