The operating system cannot assign a drive letter until the disk is
partitioned using fdisk. Now that you've got the system to recognise the
disk and got rid of the Code 10 driver problem proceed as follows:
Open a DOS window (either Start | Run | enter command.com and click enter,
or use the shortcut at Start | Programs | Accessories)
Now enter FDISK at the command prompt, and most essential, click Y when
asked if you want to enable large disk support.
You should now see at the top of the screen the line:
Current fixed disk drive: 1
Now that you have both hard disks recognised by the system you will see at
5) "Change current fixed disk drive". Type a 5 and then click enter and
you should now see your external USB disk listed as 2 with no partitions
or drive letters. Enter 2 to switch to this drive and now create a
partition layout to suite your needs using option 1 and option 4 to review
the partition layout on drive 2.

Okay, now here's what's happening. Everything in the computer is
recognizing the hard drive, except "my computer". There isn't a
drive letter for it. When I go to system properties the Maxtor hard
drive is listed and nothing has an exclamation point on it and
according to the properties, "the devices are working properly". I'm
getting so aggrevated. I just want some additional hard drive space.
