FORMATTING 40 MB INTERNAL HARD DISK DRIVES (25-4061)

Standard MS-DOS formatting of a hard drive is limited to 32 MB of disk
capacity.  To get full use of the 40 MB Internal Hard Disk Drive, there
are several simple steps required.  These steps require Radio Shack
MS-DOS, which has several additional utilities not available elsewhere.

The 40 MB Internal Hard Disk Drive is defined as a non-standard drive.
Use the following procedure to initialize your hard disk drive.  This
procedure is valid for the 40 MB Internal Hard Disk Drive ONLY.  Do not
use this procedure for any other hard disk drive.

1. Boot the Utilities diskette.  The utilities menu appears.  To choose
the Setup utility, type: 4 <ENTER>.

2. Answer the prompts for your system parameters.  When the Setup utility
prompts you for the drive type of Fixed Disk Drive C (D for secondary hard
disk drive), type: 11 <ENTER>.

3. After you complete the Setup, reboot the Utilities diskette.  The
utilities menu reappears.  To choose the Format Hard Disk Utility,
type: 5 <ENTER>.

4. When prompted for the hard drive to format, type C <ENTER> for the
primary hard disk or D <ENTER> for the secondary hard disk.  Type Y <ENTER>
to continue.

5. When the Format Hard Disk utility displays the hard disk parameters
(drive type 11, 5 heads, 855 cylinders) and asks you whether they are
correct, type N <ENTER>.  When prompted for the correct parameters, enter
the number of heads and cylinders shown on the "Factory Detected" error map
that comes with your hard disk drive.  Use the default interleave factor.

6. After you correct the parameters and flag any defective tracks, press
<ENTER> to begin the format.

When the format is complete, you can follow the normal procedure to install
an operating system on your hard disk drive.  Refer to your operating system
documentation for instructions.

NOTE:  All versions of MS-DOS are limited to a maximum hard disk partition
size of 32 MB.  To use all 40 MB of storage on your hard drive, you must use
the MLFORMAT and MLPART commands and the MLPART.SYS device driver.  Refer to
the appropriate sections of your Tandy 3000 MS-DOS Reference Manual for more
information.
