2810 HD/20  (250-3551)       Hard Disk Information     Faxback Doc. # 1809

The hard disk in the 2810 HD/20 is pre-formatted, and you should not need to
use this procedure in most cases. But if you want to reformat the hard disk
for a different version of DOS, add partitions, or reformat for any other
reason, use the following procedure.

CAUTION: Formatting the hard disk erases all information on the drive.

The initialization process has three steps. To perform the three steps, use
the following three commands found on the MS-DOS Install diskette:

1. Run HSECT to low-level format the drive.
2. Run FDISK to partition the drive.
3. Run FORMAT to high-level format the drive.

Using HSECT:

CAUTION: The HSECT command initializes the hard disk's tracks and sectors,
and erases all information on the disk. Before you use HSECT, be sure you
have copied all data from your hard disk to diskettes. Then follow these
steps:

1. Insert the MS-DOS Install diskette in the diskette drive and type:
   HSECT   press  <ENTER>
.  The following prompt appears:

   Which hard drive do you want to format (C/D)?

2. Type: c and press  <ENTER> to format the hard disk drive.The screen 
   displays the following warning:

   All data on drive c will be DESTROYED!!  Do you want to
   continue (Y/N)?

3. Type N and press <ENTER>  to exit the formatting procedure, or
   type Y and press <ENTER> to continue.
   If you continue, Hsect prompts:

   Hard drive is type 6   Number of heads = 4   Number of cylinders = 615
   Is this correct (Y/N) ?4. Type Y and press 

   The following prompt is displayed:   Formatting...

   The formatting procedure begins. Do not interrupt HSECT while it is
   formatting the drive.When the format is complete, HSECT displays
   Format complete!

After using HSECT, use FDISK. USING FDISK

To prepare the hard disk for the MS-DOS operating system, you must create 
a DOS partition. Using FDISK, you can do the following:

* Create an MS-DOS partition
* Display partition information

CAUTION: Reconfiguring the hard disk with FDISK destroys all existing
files. Be sure to have backup diskettes for all files on the hard disk
before you run  FDISK. The FDISK utility is easy to use because it uses
menus to lead you through each procedure.

To start FDISK, place the MS-DOS Install diskette in Drive A.
Then, type FDISK and press <ENTER>

In response, FDISK displays its main menu on your screen. This menu lists
four choices. Disk Options Current Fixed Disk Drive: 1

   Choose one of the following:

1. Create DOS Partition or Logical DOS Drive
2. Set active partition
3. Delete DOS Partition or Logical DOS Drive
4. Display partition information

   Enter choice: [1] Press <ENTER>. 

You can also use the ARROW Keys to choose another value, simply type the 
value you want, and press <ENTER>

How to Create a Partition:

Choose the first option on the main menu.

FDISK displays a screen like the following.

   If no extended partitions exist, the third option is not displayed:
   FDISK options
   Current Fixed Disk Drive: 

   1. Create DOS Partition of Logical DOS Drive
   2. Set active partition
   3. Select DOS Partition of Logical DOS Drive
   4. Display partition information

  Enter choice: [1]Press <ENTER>

  To accept the default selection (1) and create a primary MS-DOS
  partition. The Create Primary DOS Partition menu appears next:

Create Primary DOS Partition
Current Fixed Disk Drive: 1

Do you wish to use the maximum available size for a Primary DOS partition
and make the partition active (Y/N)...................? [Y] Press <ENTER>

To accept the default selection (Y).

FDISK pauses and then displays the following message:

System will now restart. Insert DOS diskette in drive A:
Press any key when ready . . .

Leave your MS-DOS Install diskette in Drive A, and press any key to restart
MS-DOS. Now that you have created your MS-DOS partition, you must format your 
harddisk so that MS-DOS can use it. Enter the FORMAT command as outlined in
"UsingFormat", if you intend not to use the Display Partition Data Option.

How to Display Partition Data:

If you choose the fourth option on the main menu, FDISK displays a menu that
contains information about each of the partitions on your hard disk.
For example, the Display Partition Information menu might look like this:

Partition  Status   Type     Size in Mbytes    Percentage of Disk Used

   C:1       A     PRI DOS        20           100% Total disk space is
                                               20 Mbytes (1 Mbyte = 1048576)

Press : format c:/s

In response, FORMAT displays the following:

WARNING, ALL DATA ON NON-REMOVABLE DISK DRIVE C: WILL BE LOST!
Proceed with Format (Y/N) ? _

2. To format the hard disk, type Y. Then press <ENTER>

When formatting is complete, the FORMAT command displays a message showing
the total disk space, any space marked as defective, the total space used
by the operating system, and the space available for your files.
