I have two Hard drives a 40 gb "C" and 18 gb "E"= 9 gb And "F"= 9 gb now I get a disk error 200 And drive E & F is no longer shown. How can I get Them Back Or can I ?

Hi Ed and welcome to Tech Help Forum.

I think we need some more information here. I cannot find anything on "disk error 200". What is giving you that error and exactly what does it say? What operating system are you using? Note that harddrives typically are assigned letters in sequence - so what happened to drive D drive?

Have you recently made any hardware changes? Are all connectors securely fastened? Does the second drive show up properly in your BIOS Setup Menu?

Hello
Follow up to Loat Hard Drive. System = XP Drive C = Primary Master, D= Cd-rom, E & F = Primary Slaves, G = Dvd. No changes made to computer Been Running for about 4 Years good. When power on get Warning Hard disk 1 Failure error 0200. All disks Show up in My BIOS Menu, When i select F2 To Resume I can Run ok But can't get those two drives.

I would suggest you go out to the drive maker's web site, download and run their diagnostic program on your drive - it may be able to correct any errors.
