Multiple CD-RW entries in reg

[the staring frogs of Southern Iberia]

Windows XP home on emachines T1860, 256DDR, 60Gig HD, 1.8 AMD CPU. This unit
has a Samsung 240B CD-RW drive that works until the Registry entries
pertaining to it get changed somehow.
Under HKEY LOCAL MACHINE, System there are 3 listings for control set.
Control set #1 seems to never change but control set 2&3 have multiple
listings for the CD drive. There is the Samsung and others for Saosung and
Saoswng. No typos! What could possibly be adding these entries to the
registry.
I assume the 3 control sets refer to the 3 people who use this
computer most of the time. I can delete them if I right click and change
permissions, then delete but they seem to keep returning.

I would recommend that you do not delete any Control Set(s).
It's a hard thing to recover from, if you Nick the wrong one.

To locate how many "Real" CD-RW's are in your machine, check
HKLM\System\CurrentControlSet\Enum\IDE

As to spelling, you may have Phantom devices that can exist from
CD-RW firmware flashes, which re-enumerates the device. You
can check for Phantoms by clicking View in Device Manager and
check the "Show Hidden Devices" option box. Then check your
CD/DVD devices category

You are getting corruption somewhere on your system (my guess is some piece
of hardware). Could be failing cable, could be bad drive, possibly somewhere
in the Operating System.

Here's why it looks like that.
Samsung
Sa*s*ng
m/o and u/w

'm' = ascii 109 bit= 0110 1101 *good
'o' = ascii 111 bit= 0110 1111 *bad
'u' = ascii 117 bit= 0111 0101 *good
'w' = ascii 119 bit= 0111 0111 *bad

More information - you should have multiple "control sets" in the registry.
Don't delete them. If you make changes (add/remove device drivers from the
system) it makes those changes to an unloaded "control set" and will attempt
to reload that profile on next boot. If you've ever installed a bad device
driver you'll remember having to boot using "Last Known Good" which would
have been the profile you were using at the time to install the drivers.
Current Control Set is a virtual pointer / copy of the currently in-use set.

Don't delete them.

What are Control Sets? What is CurrentControlSet?

Hey Rick, I have also had several strange occurrences that continue to
puzzle me with my CD Rom drive. I followed your suggestion in this message
about Phantoms. When I follow your directions using the "Show Hidden
Devices" option box, I see no ghost devices presented in the DM, BUT when I
go to the registry key: "HKLM\System\CurrentControlSet\Enum\IDE" I run
accross about 20 entries related to my CD Rom drive some of the entries are
misspelled entries that seem to cause a problem on a sporadic basis. For
example I can sometimes loose the RW capability of my device. Right now it
is a crap shoot as to when the OS software decides to pick up these bogus
entries and use them for a phantom drive. I wonder what would happen if I
removed the bogus entries in the registry. Any ideas??? Thanks in advance
