[comp.sys.apple] Grounding strap

adams@hpfelg.HP.COM (John Adams) (02/27/90)

Recently my //c was unable to read from the built-in drive.  Upon further
investigation of the drives inards I discovered a small metal strap stuck
behind the head preventing the head from moving backward.  The strap 
originally ws connected to one of the disk drive chassis screws (see
diagram) possibly for grounding purposes.

Can ony tell me what the purpose of the strap was and what is connected
to.
