The GX1 controller will take up to a 120 Gbyte disk, although the bios has a display limitation of 65535Mbytes.  Make sure you set the hard disk to the cable select position and put it on the innermost connectorwith the original on the endmost if you want the new drive to be the "slave".  Make sure the bios is set to AUTO for all IDE devices you have and NONE for all you don't; if you have two hard disks then both should be set to AUTO on the primary IDE.  Try these steps first. 

I would then recommend going to bios A07 - I think there were limitations in some of the early bioses on disk size.

Set the drive for cable select and see if its seen when you plug it into the CDROM connection.

Fdisk needs a patch to display the correct size.

2000/XP will not format the whole drive unless its NTFS.

WIN9X and WINME dont have this limit.

I also have an Optiplex GX1 / Service Tag: B74U9

Since getting it I have make several Up-Grades and am very pleased with the results.
I am running Bios A07 which was recommended by Power Leap for use with their iP3/T. The CPU is now running at 1.4Ghz. I installed 3 x 256 Crucial RAM = 768 RAM (the Max). I have installed 2 Hard Drives, 1 60G (Win/XP NTSF) and 1 30G (Win/98SE FAT32). I am so impressed with the operation that I got another GX1 to use for parts if needed.

Good luck

Thanks all for the encouragement.  It was either this, or reformat the small drive with a smaller OS.

At least I know it can be done, and everyone tells me to upgrade the BIOS.  Guess I have to learn how to do it

Apprecate it.

 

 

Just as a Note:

 There is a utility in your Control panel called Administrative Tools /Computer management /Storage /Disk Management.

You can see all of your drives. You can change the drive letters to all devices here as well as Format drives. (NOT THE C:\ Drive).
