Re: [disklavier] "Unprotecting" 1.44MB 2HD Pianosoft disks

2003-03-06 by Carol Beigel

Thank you for posting this!  However, it did not work for me.  My Pianosoft 
disks are 720k.  I thought ALL PianoSoft disks were double density!  I used 
AnaDisk to make an exact copy of the PianoSoft diskette - one 720k disk 
copied to another 720k disk.  I used a laptop running Windows XP 
professional.  I was surprised that Anadisk worked in virtual DOS as the 
dkvcopy does NOT!  I suppose I could try using AnaDisk to copy a 720k 
PianoSoft disk to a 1.44 disk, then perhaps this would work.  Are your 
PIanoSoft disks 1.44?
