RECOVER Floppy Pro v1.0
![]() RECOVER Floppy Pro is an easy floppy disk recovery software. It recovers files from BOOT, FAT and ROOT Folder damaged floppy disks. A single run recovers all files. It recovers files from a floppy disk that windows says "is not accessible" or "is not formatted". It is a disk level data recovery software for floppy disks.
Analyzing a Damaged Floppy Disk - WINDOWS 98SE Error Messages: WINDOWS 98SE displays this error message when floppy disk has a bad Boot sector: The disk in drive A: is not formatted Do you want to format it now Yes NoWINDOWS 98SE displays this error message when floppy disk has a bad first FAT sector in FAT copy 1 (even if Boot sector is really good and whether or not ROOT Folder has a bad first ROOT Folder sector): The disk in drive A: is not formatted Do you want to format it now Yes NoWINDOWS 98SE displays this error message when floppy disk has bad sectors (or a single bad sector) at the very beginning of ROOT Folder: A: is not accessible The system cannot read from the specified device Retry CancelTo analyze your floppy disk please download ANALYZER for RECOVER Floppy Pro v0.3 FREEWARE ANALYZER for RECOVER Fixed/Floppy Disk v0.3 FREEWARE The list below describes the various disk error conditions that can be handled by RECOVER Fixed/Floppy Disk v2.2, for recovering files from damaged floppy disks. The way to handle each disk error condition and what is needed from backup, etc. are also clearly and briefly explained. To what extent files can be recovered is also specified. The target is 100% data recovery.
Just a command line switch makes up for the lost Boot Record in the damaged Boot Sector. 100% recovery is ensured even if the floppy disk was NEVER defragmented. 100% recovery is ensured if disk defragmenter has been run on the floppy disk before the File Allocation Tables got damaged. Disk defragmenter need not have been run in the following cases: 100% recovery is ensured if disk defragmenter has been run on the floppy disk before the File Allocation Tables got damaged. Disk defragmenter need not have been run in the following cases: 100% recovery is ensured. No prior defragmentation of file system on disk is required. RECOVER Fixed/Floppy Disk v2.2 automatically uses the File Allocation Table (FAT) copy that was not physically damaged. In case of complete erasure or corruption (without surface damage) of one File Allocation Table (FAT) copy, user can always force the use of the good File Allocation Table (FAT) copy by specifying a switch on the command line. 100% recovery is ensured. No prior defragmentation of file system on disk is required. RECOVER Fixed/Floppy Disk v2.2 automatically uses the File Allocation Table (FAT) copy that was not physically damaged. In case of partial erasure or corruption (without surface damage) of one File Allocation Table (FAT) copy, user can always force the use of the good File Allocation Table (FAT) copy by specifying a switch on the command line. Raw image of Root Folder must be supplied on command line as a file. Raw image of Root Folder extracted from any backup can be used. 100% recovery is ensured. If raw image of Root Folder is not available, excepting files (actually file entries) trapped in damaged Root Folder sectors, all other files can be recovered. The OS (DOS or WINDOWS) always fails to see (even just see) file / folder entries beyond the damaged Root Folder sector. But RECOVER Fixed/Floppy Disk v2.2 has an easy way to deal with this problem. If we assume that all got damaged in their entirety, If File Allocation Tables, and Root Folder got damaged only partially, and the floppy has a bad Boot Sector If you are adamant about exploiting RECOVER Fixed/Floppy Disk v2.2 in such a case (that is, when damaged part of Root Folder had a number of subfolder entries), if you can use a folder finder utility and copy these subfolders to separate files, recovering anything in these subfolders' paths will turn out to be just a special copying process. All you have to do is start off with a subfolder passing it to RECOVER Fixed/Floppy Disk v2.2 on command line as a file and recover all the files and lower level subfolders contained in it. Repeating this process on subfolders recovered in the last run of the program, you can recover all files in that path at COPY command speed. This reduces your sector level data recovery chores to absolute minimum. FINDING FLOPPY DISK ERRORS: WINDOWS 95/98 ERROR MESSAGES
If you want to know how many Root Folder sectors got damaged, you can use DEBUG.EXE for the purpose. The following table lists the Logical Starting Sector numbers for system and data areas for floppies that will be useful when running DEBUG.EXE. All numbers (excl. column 1) are in hex.DEBUG.EXE wants sectors numbers in hex. We have used here INT 25H numbering scheme for sectors. Accordingly, the Boot Sector is Sector 0. For the purpose of DEBUG.EXE, the following table uses zero based Sector numbers as does INT 25H.
By accessing Root Folder sectors in DEBUG.EXE, you can manually check if they are ok (readable). If DEBUG.EXE cannot read a sector, you know that sector got physically damaged. USING DEBUG TO EXPLORE ROOT FOLDER (ROOT DIRECTORY) SECTORS ON A 1.44 MB FLOPPY DISKRemember DEBUG's command syntax is this:Load [address] [drive] [firstsector] [number] Warning! Don't change to another floppy while working on one inside DEBUG unless you precisely know what you are doing. TO READ 1ST SECTOR OF ROOT FOLDER:Run the following command at DEBUG's hyphen prompt. [drive] = 0 for Drive A. [drive] = 1 for Drive B.-L100 0 13 1 TO READ 2ND SECTOR OF ROOT FOLDER:Run the following command at DEBUG's hyphen prompt. [drive] = 0 for Drive A. [drive] = 1 for Drive B.-L100 0 14 1You can increase 14 to 15,16,17,18,19,1A,1B,1C,1D,1E,1F,20 in the next Load ( -L100 here ) commands. From 13 to 20 it is 14 sectors totally. For a 1.2 MB floppy disk these 14 sectors start with F and end in 1C. If DEBUG.EXE does not report anything, that sector is OK. When a sector is OK, you can dump its contents on screen by entering the DEBUG's DUMP command like this -D100If you see Folder entries there, that sector is OK beyond any doubt. |
