Over the last few months I've been getting occasional read errors on my floppy drives. At first it seemed to be only the external drive, but last week it happened on the internal. The strange thing is that most of the time it has happened on loading programs from a disk which had been working perfectly. I get an error message, then I retry many times and it goes away. Later, the same disk will load the same program many times with no sign of trouble. It did happed once during a write and trashed the floppy it was writing to. I recovered most of the files with disk salvage. I would think that if it was alignment, the problem would occur more frequently. It's really strange that I can use the same disk for weeks with no problems, then get an error which won't go away without 6 or more retries, then the next day the same disk reads normally. Could the 8520 I/O chip be the problem? Has anyone else had this type of problem? I had thought the problem was with my external drive, but now it's happened on the internal as well. Also, I have tried removing & reinserting the disk when the error message appeared, but that didn't help either. I'm using Fuji disks since this brand has been OK in the past. Any help or suggestion would be appreciated! Thanks! Claude
