When I see that a drive has an odd number of heads, do I ALWAYS know that the missing head is used as a servo track for positioning a voice coil head assembly over the proper track? And that ALL drives with an even number of heads is a drive with a head assembly positioned by a stepper motor? Thanks. _____________________________________________________________________________ Bob Davis, UofALA alum \\ INTERNET: sonny@trantor.harris-atd.com | _ _ | Harris Corporation, ESS \\ UUCP: ...!uunet!x102a!trantor!sonny |_| |_| | | Advanced Technology Dept.\\ AETHER: K4VNO |==============|_/\/\/\|_| PO Box 37, MS 3A/1912 \\ VOICE: (407) 727-5886 | I SPEAK ONLY | |_| |_| | Melbourne, FL 32902 \\ FAX: (407) 729-3363 | FOR MYSELF. |_________|

A head could be mapped out through software, though.
