CD ROM access failure

I have 2 CD ROM's on a system with win2000 pro.
One is a burner. It is configured as the Master.
I can access a disk in either drive if it is the
very first attempt after boot up.  If however, I
change the disk (data or audio), Explorer will not
provide access to it - saying that there is no disk
in the selected drive. The drives are clearly functional
as I have no problem burning a disk or playing an
audio CD.  But when I try to navigate the disks
directory, Explorer will not allow access (saying "Please Insert Disk"). I've played around with the insert notification settings - that did nothing.
Device Mangler shows no conflcts and reports that all hardware are present and accounted for.

The drive structure is as follows:
No C: drive
D:  - CD Burner
E:  - CD ROM
F:  - Main harddrive (don't ask, this computer has a long history)

I've considered the idea that my root drive being F: could
be the problem. Unless someone says absolutely that that
is the specific cause, I will not pursue it.

The problem appears to be in Explorers inabilty to properly refresh or re-poll the drives.

If anyone has any insight into or specific knowledge of this problem, your help would be greatly appreciated.

Thank you.

imadman, the problem is, indeed, because of your configuration. The first physical hard drive must be "C". You'll find the rules here:

Why is it that I can access the drives at all?
It seems to me that the assignment rules simply apply to
how a drive will be designated and therefore recognized by the operating system. The rules indicate that upon install,
the first recognized primary will be assigned 'C'. But they
don't say that it MUST be 'C'.

imadman, you can interpret the rules any way you wish, but I think the following is fairly straight forward:

BASIC Disk - Drive Letter Assignment Rules

The following are the basic disk drive letter assignment rules for Windows 2000:

*Scan all fixed hard disks as they are enumerated, assign drive letters starting with any active primary partitions (if there is one), otherwise, scan the first primary partition on each drive. Assign next available letter starting with C:

This doesn't say maybe, or most of the time, or there is an exception, it says "Assign next available letter starting with C:"

You ask why you can access the drive then. Using the disk manager function, I can partition a drive, assign it just about any letter I wish, make the partition active and format it and then use it any way I wish. The caveat here is that it might not work as intended, and as is the case most times with MS products, the problem won't surface until some period down the road.

I am having the EXACT same problem happen on my system.  Everything is exactly as it is here, except I have a C: Drive.  I am looking for a way to get into auto-insert notification and disconnect settings, but I can't find them in Win 2000.  They are apparently not in the same place as in Win 9x.  Has there been an update top this problem?

Commented:
There is another strange thing about this.  I am able to gain access to my cd-roms again when I log off of Win 2000 and back on.  All of my Windows updates are installed as well, with SP2.

1) I would get the latest BIOS and  also the newest drivers for your motherboard, inclusing any iDE drivers.
