I have three 1050 drives. Two work beautifully and the third one works fine except:
It will not format disks with DOS 2.5. It formats fine with MYDOS and the other two
drives can read disks that it formats and writes in MYDOS, but it can't format in DOS
2.5. If I format the disk on one of the other drives, I can then read and write to the
disk in the third drive without any problems, and both of the good drives can read
what the third drive has written without any problems. I also ran the 1050 CPS disk
several times through the test loops without any problems. I'm stumped.
