Lost access to CD Drives

[JoeAgro]

My Pentium 200 has four IDE devices installed.&nbsp;&nbsp;A Master HD and Slave CD burner on the Primary channel and a removeable Syquest HD (M) and CD (S) on the second channel.<br>The operating system is WIN98 SE.<br>Everything was working fine up to a couple of days ago.&nbsp;&nbsp;Now only the master devices of each channel are found.&nbsp;&nbsp;Also the devices are now running in capatability mode instead of 32 bit.&nbsp;&nbsp;Can't access from DOS either though they are found by the bios and displayed during bootup.<br>The system setup has not be changed during this transition period. I have tried to remove/reinstall, find a better driver, etc.&nbsp;&nbsp;Since both masters are accessible I think the IDE interfaces are OK but could be wrong.<br><br>Does anyone have any suggestions.

If you are running in compatability mode, then it sounds like there may be a driver conflict somewhere. What drive(s)&nbsp;&nbsp;is/are running in compatability mode? Check device manager under hard disk controllers and post what it says. Also what kind of Mobo? do you know which chipset it uses? <p>Al<br><a href=mailto: atc-computing@home.com> atc-computing@home.com</a><br><a href= > </a><br>

Both channels are running in compatability mode.&nbsp;&nbsp;I mentioned that nothing has been changed in the system BUT now remember adding 32 mg.&nbsp;&nbsp;Have to look into this and other suggestions and will post progress.<br><br>Thanks....Joe

And what virus checking are you doing. Several force compatibility mode and don't let 32 bit drivers load. <p>Ed Fair<br><a href=mailto: efair@atlnet.com> efair@atlnet.com</a><br><a href= > </a><br>Any advice I give is my best judgement based on my interpretation of the facts you supply. <br>

Adding memory should not adversely affect this issue. <p>Al<br><a href=mailto: atc-computing@home.com> atc-computing@home.com</a><br><a href= > </a><br>

Check the Performance Tab in System Properties and see what it says about the drive performance. For example, if it says MBR modified, you can bet you have a bootsector virus. If it is a driver loading from Dos it should tell you something to that effect.<br><br>If it merely says &quot;Dos compatability mode&quot; you may want to try searching the registry for &quot;NOIDE&quot;, without the quotes.<br><br>This setting will be placed in the registry after a failed attempt to enumerate a PCI based IDE controller and until it is manually removed your drives will never operate in 32bit mode.<br><br>You may also want to review MS KB article Q130179<br>for other tips.<br><br> <p>Doug<br><a href=mailto:dxd_2000@yahoo.com>dxd_2000@yahoo.com</a><br><a href= > </a><br>

Update:<br><br>As I mentioned before the IDE controllers are running in MS-DOS compatability mode.&nbsp;&nbsp;No conflicts in resources.&nbsp;&nbsp;No NOIDE entry in the registry.&nbsp;&nbsp;No bootsector problems.<br><br>Can boot with a WIN98 floppy with CDROM support see and access both CDROMs.<br><br>Leaning towards finding a virus detector or simply reformating and starting over.&nbsp;&nbsp;Since this is my wife's machine that is used only for Internet access and the little CDROM copying I do, reformating is not much of a problem.<br><br>I'm going to find the MS article mentioned first before taking either course.<br><br>Thanks to everyone that jumped in with immediate excellent troubleshooting advice.<br><br>Best Regards....Joe

FOUND IT!<br><br>I had disable 32bit disk access checked in the file troubleshooting section AND NOW I remember when and why I checked it.&nbsp;&nbsp;That will be the subject for another thread, enough for now.<br><br>Thanks to everyone.<br><br>Joe Agro
