In an effort to repair a friends system. I disconnected some of my own drives an plugged hers in mine. When I reconnected my own hardware something wasnt right. things seemed a little slow and my cd-rom could not be found. it was getting power but no matter what I tried it would not show that I had an "e" drive.The CDROM(e drive) has since reappeared, But, although I am able to function now I have many conflicts. Under hard disk controllers it says: Primary IDE Controller (dual fifo) Secondary IDE Controller (dual fifo) Standard IDE/ESDI hard disk controller. and under System Devices I have a conflict at Advanced Power Management Support. When I go into performance it states that Drives C,D and E are using ms-dos mode compatibility mode file system. What did I do wrong here? I tried to update the drivers for each but it said I already had the best ones. I checked that all my connections were good. How serious is this? What can be done?

We all hate Windows when it does this. The MSDOS Mode compatibilty can happen for a wide variety of reasons the most common cause that I have found is the DOS mode CDROM driver. Remove the driver from the config.sys or re-boot your system using stepby step confirmation and don't load the CDROM drivers in dos.

I have also expereinced this error with Corrupt IDE driver, which you would appear to have. You can try and remove all the IDE controllers from Device manager and reboot, if it doesn'tmanage to reboot itself after removing the devices (which happens regularly) it will have no effect, once the devices have been redetected they can still fail. I would go and download the IDE update for your mainboard, this will replace the driver files. It is hard to update the drivers of the IDE, most of the time they don't ant ot change or change back when you reboot.

if worst comes to worst, re-install windows to another directory on the hard drive, or try to re-install windows over the top of the current install.

There are some known issues with Windows 9x and DOS compatibility mode problems. Usually this occurs when a major hardware change up occurs.

Go to Microsoft's TechNet site, at http://www.microsoft.com/technet and search for DOS compatibility mode. It will probably have at least four or so solutions.

By the way, once Windows kicks in to DOS compatibility mode, it flips a registry key. This registry key will need to be flipped back or removed to fix the problem in the end. Again, check the website.

Hope this helps you!

It would seem that when you installed your
friends drives on your machine, windows
re-configured itself to her drives.
at this point I would run fdisk and answer
yes when it asks about fat 32.and then check
your partitions.Reboot your machine and delete
your drives, power management,cd rom etc.
reboot and let windows install its generic
drivers from your CD. Dont let windows use
drivers stored on your machine.
Also make sure you dont have config.sys or
autoexec.bat in your root dir.Windows does
not need them.Unless of course you play games.
