>Description:
Double Density disks generally do not work, they fail to mount with an input/output error and if a format is attempted the drive sounds as if it's reading from track 0 to 79 trying to find the other half of the non-existant high density disk.
On the very odd occasion that they do work, it is EXTREMELY slow (at least 2 minutes to copy a file of a few kilobytes) because it seems to be seeking from the start to the end of the disk repeatedly.
>How-To-Repeat:
Try to format or mount a double density disk.
