- George is correct that this is dangerous. This, however, is neither a bug
- nor a problem with the Win 3.1 smartdrive program.
-
- I have been using this smartdrive and a write-back cache for a few months,
- and I don't mind it at all. The only trick is to call smartdrv /c prior to
- rebooting. As a matter of fact, it is not a bad idea to do this occasionally
- as you are running (Anyone write a Windows cron utility? or a cron TSR?).
- Unix users (who have actually seen a console, or administer) are familiar
- with this potential difficulty, and have lived with it for years.
-
- The problem is PC users who don't think before they flip the switch, and
- Microsoft not trapping the warmboot vector to flush the cache before a
- warmboot. Of course trapping a power-off is a little more difficult from
- the software side.
