Can someone provide me with information about the "lazy
write" option that is available on the "DISKCACHE" line in the config.sys?  I am interested in its impact on the stability of a system.  We have some PS/2's that are very memory intensive at the moment.  Is it dangerous to have the LW option enabled?   Would power outages or any other external factors make using it risky?  Would you recommend disabling it?

Thanks for any assistance that can be provided.

Lazywrite is the process where a cache does not immediately write
the data to the hard drive.  Instead, it waits a while, in the hopes that the system will become idle in a few seconds, and then
it writes the data.

If the system loses power during this delay, then yes, you will
have lost information that would normally have been written to
disk.

It will not make the system any less stable to have it enabled.
Frequent power outages will make LW a bad thing.  However, there
is significant performance gain.  You may find the performance
loss without LW so severe that it will nullify any increase
in security.  I recommend you try it.
