| I believe the AmigaDOS LOCK command does this.

| There is a program called 'Lock' in my c: directory, which
write protects the HD (optional with a password).

Besides the more generic (and not always sufficient) LOCK command,
you may very well write a routine using SetFunction() that intercepts
Writes() to a(ny) device.

| For those with a HardFrame and 1.5C (Or thereabouts) ROM in it you can make
a partition write protected by setting the "mount" bit in the RDB to zero.
Technically, this is a bug, but is fixed in beta versions of the Hardframe
driver and a proper write protect flag is supported.
The RDPrep program makes this change easy to do. Just select the drive and
modify the partition settings.
For those with BIX access there is a graphic user interface version available in
Microbotics/Listings.

I have a Hardframe, but do not have the new version of RDPREP. I also
don't have an account on BIX. I would appreciate it if someone that
has this lastest version would upload it so I could get it from the
net. Thanks.

| 3746.6 | LOCK is not permanent | ULTRA::KINDEL | Bill Kindel @ BXB1 | Fri May 04 1990 11:51 | 4 |
| For those attempting to use LOCK, you should know that it's a SOFTWARE
lock only. You need to set it in SYS:s/startup-sequence so that it
takes effect each time you boot. It will NOT protect your hard disk
partitions from tampering by whatever (games, etc.) you boot in DF0.

| And unfortuenatly, SCSI has no standard means of write protecting a device.
You can ask a device if it's write protected, but you can not tell it to
write protect itself.
Write protect is accomplished via a jumper on devices which support it.

| 3746.8 | Kronos Can (I think) | CACHE::BEAUREGARD | Time to change this message | Fri May 04 1990 12:48 | 9 |
| If I remeber correctly, the Kronos controller will allow you to write
protect a disk. I think there is a field in the devsetup (don't
ask) that provides for this. This protection is at the device driver
level and is perhaps more secure than the AmigaDos lock. I'm not sure
if you can un-protect/re-protect the disk without generating a new
devsetup.

| 3746.9 | Beware of LOCK | VCSESU::MOORE | Tom Moore MRO1-3/SL1 297-5224 | Fri May 04 1990 13:33 | 11 |
| re:.6
<< For those attempting to use LOCK, you should know that it's a SOFTWARE
<< lock only.
Also beware that it is not completely effective. If you LOCK the drive
and then reset Preferences, the next time you boot you will get the
reset values rather than the "locked" values. This was my experience
when showing the salesman down at Leiser how LOCK works on a A500 with a
A590. I said "See there is no change. Oops! Sorry about that."

| 3746.10 | thanks | WHAMMY::SPODARYK | Binary Throttle | Fri May 04 1990 14:52 | 6 |
| Thanks for the answers folks. It seems I should pay more attention to
my documentation. Like last week when I wanted to change my workstation's
time, I asked someone who replied "try - $set time=xxx". How obvious can
it get?

| 3746.11 | | BAGELS::BRANNON | Dave Brannon | Fri May 04 1990 18:09 | 8 |
| the best "lock" I've found is an external disk drive box that
can be powered off separately from from the computer. I assume
a similar power off switch could be done for internal harddrives.
That guarantees nothing will get written to the disk by some program
going wild. Of course it's not terribly useful powered off, but
it is safe from harm.

| 3746.12 | ALFprotect | FRSOLD::ZIMMERMANN | Wer von Euch Kerls ist Kowalski | Sat May 05 1990 15:11 | 6 |

Alf-users have the Alfprotect (v1.6/can't remember the v2.0-name)
to select between protection against format or write.

| 3746.13 | SyQuest drives support hardware write protection | TPWEST::MJJONES | Cursed with a pornographic memory | Tue May 22 1990 15:21 | 4 |
| The SyQuest 44mb removable media hard drives support hardware write protection.
Each 44mb cartridge has a write-protect device that can be enabled (same
function as the slider on the 3 1/2" floppies). This activates a HARDWARE
protect, and it works (really). See topic 3789 for more details.
