Got a question regarding hard disk formatting.
Has anyone ever formatted a 1024 cylinder image (or more) with either MDM5 or CFORM on a TI-99/4A or Geneve 9640?
I tried an 8 head, 1024 cylinder, 32 sector/track with CFORM and while it reported it wrote the bitmap correctly, the bitmap was not there on the 64 MB image. Thinking something may be unique about CFORM I do not understand yet. I will try MDM5 tonight, time permitting.
Also, has anyone ever used either CFORM or MDM5 to format a MFM drive with more than 1024 cylinders?
MDM5 will allow you to enter more than 8 heads, but as designed, the HFDC without modification will only allow 8 heads. Barry Boone has an article in Micropendium that allows you to add another line so one can use 16 heads. Myself, no interest at present of this modification.
So, since MDM5 can allow more than 8 heads, is anyone aware of an issue with something greater than 1024 cylinders would be an issue? Did anyone ever have a MFM drive with 1024 or more cylinders where this was ever tested?
