Targeting 100% Data Recovery by using RECOVER Floppy Pro v1.0
- It takes a single run of RECOVER Floppy Pro v1.0 to recover all files from a floppy disk.
- With Switch /X specified, RECOVER Floppy Pro v1.0 runs at disk level to recover all files on the floppy disk.
- User interaction or looking at sector contents or any decision making by the user is not at all required.
- RECOVER Floppy Pro v1.0 does all the "What to recover" and "How to recover" thinking for you and recovers files automatically for you.
- When it is a reformatted floppy disk you want to recover files from, all you need to do additionally is just hit the ENTER Key to say YES to RECOVER Floppy Pro v1.0 when it asks whether it is a reformatted floppy disk. No more user interaction or decision making is required . RECOVER Floppy Pro v1.0 does everything for you automatically and recovers your precious files.
- To be sure you can reach 100 percent recovery rates, ensure that a reformatted floppy disk, or one that has 'entirely damaged ROOT Folder and FAT' does not have files in the ROOT Folder.

Achieving 100% recovery of files from a floppy disk is easy when
- floppy disk has a bad Boot sector.
A recent defragmentation of the file system on the floppy is NOT a requirement here.
Requires command line switch -SBn.
About Switch -SBn
- floppy disk has erased/damaged File Allocation Tables (there are always two copies of FAT in a FAT file system).
A recent defragmentation of the file system on the floppy is put forth as a requirement here to achieve 100% recovery of files. If you do not set a target of 100% data recovery, then the file system need not have been defragmented. However, defragmentation is not a requirement when you want to recover files from a floppy disk that had been quick formatted / reformatted before files were saved to it or was a brand new one when files were saved to it or if files on it had been deleted before new/updated files were saved to it.
Requires command line switch -I (if entire FAT was lost).

- floppy disk has erased/damaged Root Folder (Root Directory) but the Root Folder was backed up before the erasure/damage.
Here also a recent defragmentation of the file system on the floppy is NOT a requirement. But if 100% data recovery is your target, the Root Folder has to be available as a file from backup. If 100% data recovery is not your target, and the Root Folder on disk is only partially damaged, all folder entries in the not-damaged sectors can be recovered and saved as a file by RECOVER Fixed/Floppy Disk FAT32/16/12 v3.0 Release 3 and RECOVER Fixed/Floppy Disk v2.2; then RFD can be made to look for folder (directory) entries in the file instead of on disk. While DOS / WINDOWS cannot access file / folder entries beyond the damaged sector(s) in the Root Folder, by using RECOVER Fixed/Floppy Disk FAT32/16/12 v3.0 Release 3 or RECOVER Fixed/Floppy Disk v2.2 you can recover these good file / folder entries beyond the damaged sector(s) and recover all files in those folder (directory) paths that the OS cannot do.

If 100% data recovery is your target even when no backup is available to fill in for the damaged Root Folder, and if only a few sectors got damaged, you can recover the not-damaged part of the Root Folder and save it as a file first and then recover files. Switch -BR does the job for you. It recovers the Root Folder and saves it as a file with a name which is AROOT.DIR, or BROOT.DIR for drives A:, or B: respectively. This file is the starting point for recovering files by supplying it on command line through Switch -L.
If subfolder entries got trapped in the damaged Root Folder sector(s), by using a sector level disk utility, you can find and save the raw structures of the subfolders (subdirectories) whose entries got trapped. That is, you take out the real folders whose entries got trapped in damaged sectors in their parent folder. Once this is done, 100% data recovery is an easy target. You can use RECOVER Fixed/Floppy Disk FAT32/16/12 v3.0 Release 3 or RECOVER Fixed/Floppy Disk v2.2 to recover all files in all those folder paths easily.
If file entries got trapped in the damaged Root Folder sector(s), your target has to be a bit lower than 100% because these files cannot be recovered except by using a sector level string search utility.
