I've got a question and I wanted to keep it separate from the DREM discussion.
In MDM5 while formatting for a real MFM hard drive, there is an entry for heads. I have always used what is labeled on the drive. If it says it has 5 heads, I enter 5.
In reality though, does MDM5 and I guess the rest of the world treat it as a total of 6 heads, but starting at as head 0, head 1, head 2, head 3, head 4, and head 5?
