Floppy Diskette Seek Failure - Help!

Dear Dell,

 

I have a Dimension 8400 from you and have recently noticed that everytime I boot up my PC an error message appears in DOS:

 

 'floppy diskette seek failure. Strike the F1 key to continue, F2 to run the setup utility'

 

I don't have a floppy disk drive on the computer, either internal or external - just one DVD drive and one CD-RW drive.

 

I have searched through your Knowledge Base and it suggested I enter the F2 setup and disable the 'Diskette Drive' under the 'Drives' sub-list. The factory default is 'Internal' but as per the instructions I changed it to 'Off' and saved/exited setup.

This solved the problem in the sense that I no longer have a 'floppy diskette seek failure' error message, but this option has also disabled my DVD and CD-RW drives - they no longer are listed in My Computer and don't work! Restoring the option back to 'Internal' and/or resetting all the setup-factory-defaults brings back the 'floppy diskette seek failure' error message but ALSO, my DVD and CD-RW drives still don't work!

 

Please advise me on fixing this 'floppy diskette seek failure' error message and also in restoring my access to my DVD and CD-RW drives which no longer work.

 

Thanks - Peter.
