Continuing with my own experience as I use it, and feedback from others, I have once again updated ImageDisk. 1.05 = Fix to interleave logic (could mix up Cylinder/Head mapping). Rename IMDAM to IMDU (IMageDisk Utility) and add capabilities: - Handle larger tracks - Remove specific tracks/sides - Convert image to raw binary sector dump - Translate data rates within image - reGenerate tracks with new interleave factor - Append, Replace and Extract comment record The update is available on my site (see sig), in the "Disks/Software imaegs" section - imd105.zip near the top of that page.
