Note for Windows 3.1 user :
If you have problem for reading/writing floppy, try add in WINIMAGE.INI file
the line :
UseDpmi=TRUE
or
UseIoCtl=FALSE

UseIoCtl (default : TRUE) say that read/write floppy is done by DOS IOCTL
if UseIoCtl=FALSE, WinImage use Int 13h (BIOS), like version 1.0 and 1.11

and say me your configuration.

There is another line you can add in WinImage.ini :
AutoRetry = TRUE 
AutoRetry (default = FALSE) say that WinImage do 1 retry when there is a
floppy error.

NT User can change AutoRetry in Software/WinImage key in registration database
(run REGEDT32, and use the HKEY_CURRENT_USER window).
