On my Windows 7 (64-bit) box:
1. Attached a 1.44M USB diskette drive. Noted that it then appeared in Windows 7 as drive B: (already have an A
.
2. Ran WinImage 9.00
3. WinImage: Opened the first image file, Dos622-1.img
WinImage showed the contents of the image file.
4. WinImage: On menu bar, chose [Disk] then chose [Use floppy B:]
5. Inserted an already used 1.44M diskette into drive B:
6. WinImage: On menu bar, chose [Disk] then chose [Write Disk]
7. WinImage: In response to the 'disk is not empty. Continue?' type question, answered affirmative.
WinImage wrote the image. During that time, a 'Writing verifying' window was displayed, and that included a progress bar.
I then used the diskette to boot one of my computers into DOS 6.22 [pressed F3 after the SETUP screen appeared].
----------------------------------------------
I then retried the operation using a blank diskette. The only differences were:
* the 'disk is not empty. Continue?' type question was not presented, and
* a formatting' pass on the diskette was done before the 'Writing verifying' pass.

In case it is relevant, the motherboard (980DE3/U3S3 R2.0) supports 1.44M drives (my A: is an internal 1.44M drive)
