I have recently installed this in my Gateway computer as a slve drive to the existing 10 GB drive.
I have followed the IBM instructions using
FDISK and this gave me a D: drive whisch formated OK.
Unfortunately my primary disc was already partitioned as C: 2 GB and D: 8GB.

To get the new drive working I had to remove the partition on the primary Hard Disk and this allowed Windows to recognise the 25GB new drive which has functioned OK.
I thought I would be able to reformat the existing C: drive to the full 10 GB but FDISK refuses to allow me to do this.

I am obviusly doing something wrong. can anyone help?

MS-DOS first assigns drive letters to Primary partitions in the order or Primary Master/slave secundary master/slave, then it will assign drive letters to the extended partitions.

In your case your first drive has a primary (C) and a extended (D) partition.
Your added drive with primary partition will become drive (D) and your first drive extended partition will become (E)

To keep your original drive (D) (D) you have to stop creating primary partitions but immediately creat extended partitions with FDISK.

So your second drive will have to be FDISKed as a extended partition and will get drive letter (E).

Thanks for the information on partitioning the drives. It appears that I may have created the new 25 GB drive as a primary drive. I thought MSDOS would automatically give another letter to the old D: drive.

As I am in the midst of editing with lots of video files on th 25 GB drive I shall have to wait awhile to have another go using FDISK.

Thanks for responding so quickly.

The problems of getting the drives working OK seems to now be solved by a round about way.
I had the problem that FDISK gave my second drive the same Drive letter as the partion on the primary drive. To get the second drive to be recognised I had to disable the D: drive on the primary disk.
This happened each time I attempted to partition the primary disk to get back my lost 8GB.
I decided to try partitioning the primary drive with a very small drive which was allocated D: and a very large Drive allocated E: I found that this had now moved my new 25GB drive to drive F:.
I then disabled the very small drive allocated as D: and found that everything then moved back one letter. I have the primary drive as C: 2GB and D: 7.9 GB and the new drive as 25 GB at E:. There is a small amount of the first drive not in use but I can live with that.
