As of Sunday, June 12, my 5.25 platinum drives for my platinum IIe are no longer reading or writing to disks. I am not sure what happened, Saturday they were working fine. I sent Copy II Plus 7.1 to a 3.5" disk, tried formatting disks and was getting an error saying it couldn't read track 00. I tried adjusting the speed, but C2+ was showing the speed as being extremely erratic, one time it would say 300, the next it would say 147, jumping all over the place. I know that the disks are old, and probably are slowing the drive down. Could it be that they need an alignment adjustment? I tried another drive, got the same results with disks, speed and formatting. Maybe I should buy some good disks, I can't believe that all the disks that I have are all bad.
