both cd drives inaccessible

running windows xp home. both cd rom and cd rw are inaccesible to explorer, and neither will read a disc. both drawers are operable, and there are no yellow alerts in device manager. in fact, dm says both drivers are working properly. asus a7v8x-x mobo, bios set to auto and both bios and post show both drives. am running cdrw 24x10x40x master, cd rom 56x slave on ide 2, and two removable hard drives on ide1.
have tried removing from dev mang. and rebooting. no go.
also a couple of suggested regedit fixes. no go.
can anyone help make it go.
thanx

 

Just a little info please.
Was this something that just happened one day when you booted up?
What registry changes did you try?

 

Check the cables.

 

didn't change registry; that was in reference to a forum suggestion to delete a certain registry that i didn't have.
it's a new system that i've slowly been adding program to for the past 3 weeks, although for the past 10 days or so i've not added anything from a cd drive-- i've been tweaking norton antivirus problems, installing sp2, and numerous other small problems, so i can't pinpoint when the problem occurred. just know that they both were working fine, and now they're not.
have already checked cables and pin settings and like i said, they show up fine in post.

 

This article from Microsoft is worth reading if you haven't already done so

What happens if you only hook up one drive at a time?

 

Do they show up under Disk Management? (Admin tools/computer man./disk man)

 

yes and even shows "healthy" if disc is inserted

 

thanks to everyone for their help, but i seem to have solved the problem! I posting this for others' searches who might have the same problem. both cd drives not working: apparently there is a conflict between win xp and other cd copying programs such as nero, or Adaptec Easy CD Creator. here is a link mentioning the problem http://support.microsoft.com/defaul...port/kb/articles/Q270/0/08.ASP&NoWebContent=1
but it only mentions easy cd and other "third party CD-Writing Software" as the culprit and not NERO INCD

bottom line; if a cd drive becomes inaccessible the FIRST thing you should do before messing with any registry fixes is to REMOVE ANY CD PACKET WRITING SOFTWARE, REBOOT, AND WA LA! DRIVES WORK.
