I haven't heard of this problem with 1571's, but I suppose it's the same
problem as often occurs with most Commodore drives (IEEE or serial bus) whose
heads have been pushed beyond normal limits- they get stuck.  Although you
said you initialized the drive (OPEN 15,8,15,"I"), that usually 'unsticks'
the head by forcing the DOS to move the head to track 18 (often accompanied
by the most horrible grinding sound...).  If all else fails, you could open
up the drive and, with your finger, gently push the head mechanism back from
the 'hub' (that's where track 35 and beyond live). Don't do this with a disk
installed, power on, or a valid warranty :-)

You will find most 'turbo-hacker-back-um-uppers' that performed miracles for
the sluggish 1541 will run afoul when used with a 1571.  :-(
