This might be a dumb question. I bought some new in box 5.25" Verbatim DS/DD disks for my Apple IIe, and they work great, but I am trying to figure out how to utilize the back side of the disk. Someone at my work told me that I had to notch out a hole like the small square hole on the side on the opposite side, so I have tried that out and it doesn't seem to change it.
If it makes a difference, I took both of the drives apart and cleaned them up on the inside and the heads and stuff, and they both work great. They are both the "Unidisk" variety.
Also, is there a particular way to make the ADTPro disk bootable? Is there a particular way to get ProDOS or whatever it needs on it? I am very familiar with MS-DOS, but the apple 8 bit stuff is kind of new to me.
Thanks for the help.
The error message is "Check disk or drive door"
