I have a floppy disk that contains 3 important files.

In Windows Explorer, when I click on the A: drive, I get a prompt: Do you want to format the disk now?  I click "NO" (do not format).

When I run a chkdsk on the floppy I get:

Microsoft Windows XP [Version 5.1.2600]
(C) Copyright 1985-2001 Microsoft Corp.

C:\>chkdsk a: /F /R
The type of the file system is FAT.
An error occurred while reading the file allocation table (FAT 1).

Volume Serial Number is 1731-18F5
Windows is verifying files and folders...
File and folder verification is complete.

Windows is verifying free space...
Free space verification is complete.

Windows has checked the file system and found no problems.

    1,457,664 bytes total disk space.
      741,888 bytes in 3 files.
      715,776 bytes available on disk.

          512 bytes in each allocation unit.
        2,847 total allocation units on disk.
        1,398 allocation units available on disk.
Some file allocation tables (FAT) are unwriteable.

C:\>dir a:
The volume does not contain a recognized file system.
Please make sure that all required file system drivers are loaded and that the v
olume is not corrupted.

It is the 3 files (741,888 bytes) that I must recover.

How can I recover the 3 files.

Your help is GREATLY appreciated.

Get test disk or recuva, one of those should do the trick.

There is no link to click to get "test disk" or "recuva".

You try the floppy disk in another machine.  The present floppy drive may be dirty, dusty or have misaligned heads.  You can buy floppy drive cleaning kits but they may be hard to find.

Other techniques.  Wiggling the floppy back and forth while file reading is occurring.  This is desperation stuff.

Recuva http://www.piriform.com/recuva/download

TestDisk http://www.cgsecurity.org/wiki/TestDisk

But try another machine first.

>>>An error occurred while reading the file allocation table (FAT 1).
It seems that the Windows in unable to read the FAT1, however on typical 1.44Mb floppy disk the data is stored on sector range 33-2879 which is often called as data area.

See the details below to recover the data:

NDD (Norton Disk Doctor)

I am unable to find the second utility mentioned in the article above which is Disk Editor, however there are many you could find on the internet.

I hope that would help
