Resolved Problems
Note Do not use the dir command to verify the contents of the diskette. There is no FAT (the DOS
file allocation table) on LightStream 2020 distribution diskettes, so there can be none on your backup
diskettes. Consequently, if you enter dir a: or dir b:, DOS issues a read error message.
If Your PC Has Two 1.44 MB Floppy Disk Drives
For each LightStream 2020 software distribution diskette, do the following:
Step 1 Insert the distribution diskette in the floppy disk drive. (In the examples shown here, this is
Disk Drive A.
Step 2 Insert the blank, formatted diskette in the second 1.44 MB disk drive. (In the examples
shown here, this is Disk Drive B.
Step 3 Enter the following command at the DOS prompt:
C:\> diskcopy a: b: /v
Step 4 The program copies the data from the distribution diskette in Drive A to the backup diskette
in Drive B.
If Your PC Has Just One 1.44 MB Floppy Disk Drive
For each LightStream 2020 software distribution diskette, do the following:
Step 1 Insert the distribution diskette in the floppy disk drive. (In the example shown here, this is
Disk Drive A.)
Step 2 Enter the following command at the DOS prompt:
C:\> diskcopy a: a: /v
Step 3 The program reads a portion of the disk contents into memory. When it prompts you to do
so, remove the distribution diskette and insert a blank, formatted diskette into the floppy
disk drive.
Step 4 The program copies the data from memory onto the diskette. When it prompts you to do so,
remove the backup diskette and insert the distribution diskette into the floppy disk drive.
Step 5 Alternate Step 3 and Step 4 in response to program prompts until the disk copy is complete.
