[Feature Request] properly dump IBM-PC 360KB floppy on 1.2MB drive

[wylda]

With bellow mentioned settings, I am able to create SCP dump without any issue. Unfortunately when I use HxCFloppyEmulator.exe v2.1.24.1 to export this SCP into IMG (RAW sectors) it list files and its filesize correctly, but content of those files is scrambled (two initial small files are correct and the rest of 45 files has different scrambled content).

I also tried "SAMdisk.exe scan my_image.scp" and it displays following warnings (maybe harmless?):

Code:

Warning: unknown MFM mark (00) on cyl 5 head 1 at offset 3350
Warning: unknown MFM mark (FC) on cyl 13 head 1 at offset 5298
Warning: unknown MFM mark (FC) on cyl 13 head 1 at offset 5298
Warning: unknown MFM mark (61) on cyl 27 head 0 at offset 7463
40 Cyls, 2 Heads:
300Kbps MFM,  9 sectors,  512 bytes/sector:
  0.0  1 2 3 4 5 6 7 8 9
Warning: late track start may indicate missing first sector
...

When i use WinImage, it creates 360KB image properly with correct file checksums.

Back to the SCP - I have 1.2MB drives (3x TEAC & 1xNEC) and dumped this 360KB floppy with these SCP setting:

• Drive-Type: 5.25" - 96TPI
  
• Weakbits: Fixed
  
• Density-Reads: Low
  
• Index-Sensor-Reads: Required
  
• Backside-Control: None
  
• Preservation: Checked
  
• Disk-Types: IBM 360K
  
• Copy-Mode: Index
  
• Half-tracks: Checked + Unchecked (did two dumps)
  

Not being able to properly create an image dump, when WinImage can handle that, would be pretty frustrating. 

I still hope, that this can be fixed
