I am considering the best way to transfer my old floppy disks (720kB and 1.44 MB) to my hard disk. I have access to Windows XP, Windows 7 and Linux machines with floppy disk drives. After searching around I have come up with some candidates. I know some of my disks are boot disks or contain hidden files but no disks have any copy protection. I also own a copy of SpinRite so I guess I could use it on bad disks after I manage to copy as much as possible first. Any suggestions on which program you think is best or feedback on programs you have used are appreciated.
rawread target-file floppy-drive [–image]
target-file = DOS filename, where to write the contents to.
floppy-drive = Drive letter ( A or B ).
–image = optional, if given rawread expects a simple zImage
starting at track 0 head 0 sector 1
This floppy usally has been generated via a linux
command like ‘dd if=zImage of=/dev/fd0’ or via
‘rawrite’ under DOS with zimage as input file.
Floppy Disk Copy
This program copies data from and to floppy disks in direct image format.
FDCOPY (02.01, 04/01/99) - Floppy Disk Copy
usage: FDCOPY [-S (SIZE)] [-D (SIZE)] [-T] (SOURCE) (DEST)
FDCOPY copies floppy disk images to and from disk files. A floppy disk
image is an exact copy of the floppy disk, sector by sector.
(SOURCE) specifies the source floppy disk drive or disk file.
(DEST) specifies the destination floppy disk drive or disk file.
To specify a floppy drive, use 0 or A: for the first floppy drive,
1 or B: for the second floppy drive. (Yes, I realize that A: and B:
are really DOS drive assignments, but its commonplace to reference
the drives like this.)
When a disk file is specified, the size of the disk file must be one
of the following:
Corresponds to floppy drive
Filesize Size Geometry Media
1474560 1440K 80.2.18 3-1/2 1228800 1200K 80.2.15 5-1/4 737280 720K 80.2.9 3-1/2 368640 360K 40.2.9 5-1/4 327680 320K 40.2.8 5-1/4 184320 180K 40.1.9 5-1/4 163840 160K 40.1.8 5-1/4
-S (SIZE) specifies the drive size of the source.
-D (SIZE) specifies the drive size of the destination.
(SIZE) must be 1440, 1200, 720, 360, 320, 180, or 160.
If the -S and/or -D options are not specified, the size of the source or
destination is determined as follows:
If the source or destination is a physical drive, the drive size reported
by the BIOS will be used.
If the source or destination is a file, the size of the file will be used
to determine the drive size. See the table above.
-T specifies to read/write full tracks.
The default is to read/write one sector at a time. The -T option can
speed up the copying under some circumstances.
FDCOPY is primarily used to manipulate image copies of floppy disks,
but can also be used to convert floppy disks from one format to another
based on the geometry rather than the data stream. When converting,
the (SOURCE) is read and cylinders/heads/sectors are padded or
truncated as necessary to fit the (DEST). For example, copying a 360K
image to a 1440K disk will only use cylinders 0 to 39, heads 0 and 1,
and sectors 1 thru 9 of each track. Copying from a larger size to a
smaller size is not recommended.
When copying to/from a floppy, if the format of the floppy disk does
not match the floppy drive format as reported by the BIOS (i.e. copying
to a 360K floppy in a 1200K drive), the -S or -D option should be used to
indicate the correct format of the floppy disk.
If errors are encountered while reading a floppy disk, the data for the
sector/track is cleared (in the memory buffer), written to the
destination, and the processing continues.
If errors are encountered while writing a floppy disk, the sector/track is
skipped, and the processing continues. FYI: The destination floppy
probably has a bad sector and should not be used.
FDCOPY does NOT format floppy disks. When copying to a floppy, the floppy
disk must be preformatted.
C:>fdcopy -t disk.img a:
Parse parameters. Open source file if specified. Open destination file if
specified. Copy source file/disk to destination file/disk.
Useful for creating and storing floppy disk images rather than files. Has the
unique ability to resectorize a floppy based on the logical format rather than
the physical format.
“Choose floppy type from 360K , 720K , 1.2M , 1.44M :”
- Select the number corresponding to the size of the floppy disk you
wish to clone. RESQFLPY will check if there is enough free space for
the image file on the default drive. If not, the program will abort,
indicating there is not enough free space left to complete the
“Produce (I)mage of floppy or ®econstruct from image? [I/R]”
Select “I” to produce an image file of the SOURCE disk, or “R” to
copy an image file you have already produced to a new, formatted
floppy known to be free of defects.
The image file produced has the filename “RESQ-IMG.FIL”. The image
file will be placed in the current directory, on the default drive.
“In which drive is the source (or target)? [A/B]”
- Select either drive “A” or “B” as the drive for RESQFLPY to work
with. Once this phase of the process has begun, you can hit ESCAPE
to abort the process, if you wish.
If you have already created an image file, you will be prompted with:
Step 4: Image file exists, overwrite it? [Y/N]
- Select “Y” to overwrite the existing image file. Selecting “N”
to aborts the process with the message “Operation completed” to
indicate the first image file was not overwritten.
When RESQFLPY starts the process of copying sector by sector of the
SOURCE disk into the image file, you can abort by using ESC. The
processs will then terminate with the message “Operation failed.”
The generation of the image file can take several minutes as RESQFLPY
reads and writes each sector of the SOURCE to the image file. Please
be patient. You are kept advised of the success of the read operations
by the dots ( . ) and the read failures by the x’s. Observing this
display is informative. You will be able to visualize the extent of
the damage on the SOURCE disk.
Once you have successfully created an image file, run RESQFLPY again
to copy the image to a CLONE disk. RESQFLPY will look for the file
RESQ-IMG.FIL in the current, or root directory, when you choose to
create a CLONE disk.
Be sure to use a new, unconditionally formatted floppy for your CLONE.
Use DOS unconditional format (DOS 5 or higher) by issuing from the
command line: FORMAT drive_letter: /U. In case there are bad sectors
on the target floppy, then RESQFLPY will detect them with its internal
verification. The program will abort and display a message “Target has
a bad sector or is improperly formatted”. You can then retry with a
reformatted floppy or with a fresh disk.
- Roadkil’s Unstoppable Copier
Recovers files from disks with physical damage. Allows you to copy files from disks with problems such as bad sectors, scratches or that just give errors when reading data. The program will attempt to recover every readable piece of a file and put the pieces together. Using this method most types of files can be made useable even if some parts of the file were not recoverable in the end.
The program can be used as a daily backup system using its batch mode functions. A list of transfers can be saved to a file and then run from the command line to perform the same batch of transfers on a regular basis without having to use the GUI interface. The program supports command line parameters which allow the application to be run from schedulers or scripts so it can be fully integrated into daily server tasks.
Maybe this could work since it seems to have a function for not getting stuck on bad sectors?
CDCheck is utility for prevention, detection and recovery of damaged files with emphasis on error detection. CDCheck supports DVDs.
It supports CRC files and binary compare. CDCheck can be used on all files visible by your OS which means all files that you can see in Windows Explorer (CDs, floppy disks, disk drives, ZIP drives…).
CDCheck reporting features tell you exactly where the problems are. Files on CDs, zip drives, USB keys etc. can get damaged in a number of ways, so the program helps you determine whether your data is safe before it’s too late.
The program also provides extremly fast binary compare for effectively checking that file transfers (burning, copying…) were accomplished successfully and alerts you of differences. Besides that CDCheck supports creation and checking of MD5, CRC-32, SHA… hashes in SFV, MD5 and CRC file formats.
The program has the ability to check files with hash files in order to check them for possible loss of data or to verify if files were damaged during transfer. The program can be used with all local or removable media (CDs, DVDs, disk drives, floppy disks, ZIP drives, USB keys…) visible by the operating system (Windows Explorer) and also with audio CDs.
