DVDROM unrecognized by system

[oldfish 0]

Hi,

 

My Windows2000 can not recognize my Samsung 16X DVD ROM which

comes with my DELL PIII system? I had it working properly

before, but after i install/unistall several creative

sound card driver or webcam drivers, the system can

not recognize my CDROM( No letter) and i can not

add new hardware... But i can boot directly from CDROM

driver. Anyone have similar experience and how can i solve the

problem?

 

Many thanks.

Hi, wolf:

 

Thanks for your hint. But the problem is: i can not even locate

my CDROM drive in device manager. There is nowhere showing hardware

conflict. It seems the system can not find DVD at all. But i

can see it listed in BIOS configration. I also able to use the CDROM

if i booted in DOS mode.

 

Thanks for your attention!!

Checked here:

 

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contr

ol\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}]

 

"UpperFilters"= Cdralw2k

"LowerFilters"= CDr4_2k

 

 

C) After a right click on My Computer, Manage, Storage, Removable Storage, Physical Locations, do DVD-ROM appear?

 

my drives appear in Physical Locations under removable storage, but they have a red "X" on the left side of them. But there isnt a mention of what type of problem there.

 

But i do not know how to make an expand. My W2k CD start up automatically installation and can not allow me to expand CDsys file.

 

Could you give me more hint?

 

I have tried to remove CDr4_2k from the registry key value and rename

file CDr4_2k.sys to CDr4_2k.sy_ but still not solve the problem.

That means the DVD drivers are available on hard disk but something interferes and prevents activation.

 

Check this note about complete removal of ECDC Registry entries on a Windows 2000 system:

Reinstallation of Aspi drivers is a safe move:

Thanks again for your help!

 

But it seems reinstall of APCI layer is not helpful.

 

I did installed a UDF CD reader downloaded from website,

I tried to clear the key mentioned in the articel but seems not

work things out.

 

I am trying to recover cdrom.sys but i do not know how i

can get the file since the CD can not recognized by the system.

 

again i can not see CD listed in Device Manager.

 

I can reinstall the system, but i would like to understand

the real reason that causing this incase i am running into this again.

 

Got any more hints? Thanks!

Clearly the only solution is to reactivate the standard associations found in the Windows 2000 Registry. They are all included in the following lines. They normally link CD and DVD file system drivers and the CD and DVD hardware drives. Please copy these lines to a Notepad file; name it CD_install.reg. Then make a complete back up of your registry. Double click or right click on CD_install.reg and Merge in Registry. Reboot and check DVD.

Hi,

 

I desperately reinstalled the whole system.

Now everything is working.

 

Just when i installing the Intel IDE Ultra

driver when i realized my problem:

 

i removed one ATA100 device driver one day.

(when i see there is two ATA100 device so i

just stupidly delete one)

That actually killed my 2nd IDE interface.

I think that is the reason that the system

can not locate DVD drive. So the solution could

be reinstall ATA driver and get the CDROM back.

 

It seems a pretty reasonable reason for me.

But anyway i reinstalled the whole system.

It's running great now and thanks agian for

your kind help.
