[Coco] resurrecting 5" disks

[Steve Ostrom]

Bob, I'll add my opinion here also.  I have ordered literally thousands of 
disks from eBay.  I'll run into some where the recording surfaces of the 
disks have been deteriorating.  They don't make a howling noise, but they do 
make a very load rasping noise, almost like sandpaper was put in the drive. 
Very often, my disk drive will no longer read or write after trying to read 
one of these disks.  If you look at the disk surface closely, it looks like 
there are tiny fish scales coating the entire surface.  When this does kill 
my drives, running a disk cleaning kit always removes the build-up on the 
heads that accumulated from the disk surface.  Is this possibly your 
problem, or is it caused by a damaged sleeve that others have mentioned?  I 
have also needed to replace a damaged sleeve on a disk that contained Coco 
data I couldn't afford to lose.  Good luck!
