* 4 heads (maybe configured by X-DDOS)
* 614 cylinders (maybe configured by X-DDOS)
TFM's comment: For FutureOS I researched this hard-disc and I found 17 sectors of 512 bytes per track. It has four heads and 615 cylinders. For optimum speed the sectors and tracks have to be read / written in a defined sequence to reach maximum data transfer speed (about 80 kb/sec). It's not the case that number of sectors, heads, tracks etc. can be redefined (neither software, nor jumpers). These are real hardware values!
