Hard Disk problems

About a week ago we rebooted the old computer my kids use and got a divide overflow error.  Apparently it was something to do with the hard drive.  There had been problems with that drive before, so I had another hard drive (6.4 gig western digital)that we were not using that is newer and I knew was working perfectly in my old 486-100, so I installed it.  This computer is a Pentium 133. Then the problems really started.  The bios could not pick it up in the auto detect IDE drives, but if I set it to auto in the CMOS setup instead of user specified, it found it and correctly reported the size.  But after booting up, I got a hard disk failure (80) message.  So I inserted a boot disk and got it up from the floppy drive.  Used the EZ Drive floppy from the drive manufacturer.  It found both the hard drive and the CDROM drive, formatted and partitioned the hard drive.  I also used the EZ Bios since it reported that my actual bios could not support a drive that size.  Rebooted again and got the same hard disk error.  The drive appears to be working, but the computer cannot see it.  DOS doesnt see it.  If I take it out and put it back in the 486..it works fine.  Suggestions?

You say that you are using a Western Digital hard drive? Do you have any jumpers on the drive? If you do, then that might be your problem.I Know that Western Digital, as master does not work if you have on the master jumper. Try taking off the jumper, so no jumpers will be on any of the pins, and then looking for it in the bios with your IDE Detect function. That should work...

Ok there is a program diskinfo.exe (I have a copy ... tomcat203@geocities.com) use that to confirm that The drive is hooked up ok and the specs of it.
Enter the values manually as a user drive.
Are there any slave drives?/ is this one a master?

It is the master and the jumper is set correctly.  I double checked all my connections after the first time.  No slave drives connected.  The strange thing is that when EZ Drive formatted and partitioned, there were no errors and it apparently wrote the startup files needed to boot from the hard drive to C.  It read the drive info and displayed it.  When it boots up the information shows the correct drive is there.

Thank you.  I went immediately and tried it and it booted up into the DOS prompt without having to go into the CMOS setup.  Simple and easy fix.
