I too am having similar problems.  The drive often has trouble when I put
a new disk in the drive.  It gives Drive Not Ready like the disk is not
formatted.  I usually have to correct this by pushing the disk farther
in by hand with the drive door shut.  Then maybe it will like it.  It also
had trouble formatting brand new disks, giving Bad Disk errors or having
read/write errors shortly later (the disks are double sided, single density).
I took it to a local guy to get it aligned (I figured that was probably it)
but he said it was in perfect alignment, and could find nothing wrong.
So, I'm interested in hearing what people have to say about this.  Thanks
