Retain Floppy serial number and Volume name
William Hymen
licensed software on it. I just bought it today.
However, the install system requires the volume
label and serial to be a known value, so I just can't do
a diskcopy. The backup needs to be identical.
This is my one and only copy, so I really
want to make a functional backup.
Thanks in advance.

Use any of the DOS-based shareware or freeware programs
which convert the contents of a floppy disk into a 'disk
image' ...which is stored as a file on your hard disk.
Any number of floppy disks -- identical to the original
disk -- may then be reconstituted from this 'disk image.'
There are many programs of this type, including TELEDISK,
RAWRITE, and numerous others.
My favorite such program is COPYQM, a shareware program
from Sydex (the shareware version is fully functional).
Any 'Net search engine should turn up a link.

Number that you may want (as long as it is a HEX number).
But it's also very easy to do this with Debug.
How to change V(olume) S(erial) N(number) using DEBUG
Example below is my own harddisk with has FAT16
Note1: All numbers are hex
Note2: On FAT32 disks the Volume ID number is at offset 43h !!!!!!
I change the Volume Serial Number 000F0070 into 11223344
Notice the number is stored reversed, that's standard on a PC
Start up in DOS!!!!
Take care the DEBUG program is present and on PATH
If not confident try this first on a floppy!!!!!
Drive A:=0, drive B:=1, drive C:=2, drive D:=3 etc.
Volume Serial Number is at offset 27 in the bootsector which is sector 0
1. Run CHKDSK on the drive you want to change, note Volume Serial
Number
2. DEBUG ENTER this starts DEBUG, all DEBUG commands to be followed by
ENTER
3. Load at offset 0100 of harddisk C:(2) the bootsector(0) only 1
sector(1)
4. Show contents of the first 128 bytes of the bootsector
5. See the Volume Serial Number at offset 27, here 0127 because the
sector
has been loaded at offset 0100
6. Enter at offset 0127 the four bytes in reversed order, must be
HEX!!!
7. Show again the first 128 bytes of the bootsector for confirmation
8. Write the sector back to the disk
9. Quit DEBUG
10. Run CHKDSK notice a different Volume ID number
(This is step 3
Loads at offset 0100 from drive C:(2) the bootsector(0), load 1
sector(1)
-L 0100 2 0 1
(This is step 4, show contents from offset 0100)
-D 0100
(Step 5 you see this, notice your old ID stored reversed)
( Offset 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F)

Volume label is easily set by the MS-DOS command (yes, you guessed
it) LABEL.
All the best, Timo
