Open Control Panel then System then Device Manager.

Expand the CDROM item and double click the CD device. Select Settings. If
Auto-insert notification is checked then the system will regularly check to
see if a new disk has been inserted into the drive. Each time it checks,
the hard drive activity light will flash.

Thank you, Jeff.

My technical skill level is low. Could you please tell me how I check the
configuration of CD devices?

Please note that the way I created this new drive is by copying the files
from the old drive. Everything should be identical on the two drives.
The
only thing that is different is that I installed Windows 98 again using
the
original windows 98 CD-ROM. If configuration of CD devices is a part of
Windows install, then the two drives may have different configuration.

Regards,
Satish

The usual reason for this blinking is that Windows thinks there is an IDE
device (such as some CD-ROM drives) that does not support the media
change
signal, so it checks the IDE devices every few seconds to see if it needs
to
report that the disk has been changed.

You say it doesn't happen with the other hard drive, and it seems from
your
description that you are therefore running a different operating system.
See if there is a difference in the configuration of the CD devices,
where
one is set to detect media changes and one is not.

My hard drive light flashes every few seconds as if the computer is
reading/writing.

I have read responses to similar questions, but think my problem is
different. Here are the facts.

I copied contents of one of my drives to a different drive, including
reinstall of Win 98 on this second drive. When I make the new drive
the
master and the old the slave, I have this problem. It does not happen
with
my old drive.

This happens even when I am not on the internet or doing anything else
at
all.

Thanks.
