[vcf-midatlantic] Bad disks

[Jason Howe]

Agreed that it may be the drive.  When I've seen issues across a bunch of 
disks all of a sudden, usually a quick swab of the head clears the issue 
up.  For some reason this happens more with my Apple II than my Atari, but 
I think its because more of my Apple II disks are of questionable 
condition.

Which brings me to my next point, it could also be the brand of disk. 
Buying NOS 3M disks, I've not had a bad one yet.  I have some NOS Control 
Data disks which make nice decorations...

Good luck!
