If, instead, the drive spins at a Constant Linear Velocity (CLV: ie, the same amount of magnetic media passes under the head per second no matter where on the disk you're accessing), each bit can take up the same amount of magnetic media, which means you can store more bits per track towards the outer edge of the disk. If you're writing the same number of bits per second, this means each bit takes up a larger amount of magnetic media at the outer edge compared to the inner edge. This means that towards the outer edge of the disk more magnetic media is passing under the head per second than towards the inner edge of the disk (with a larger circumference, a constant angle will represent a longer chunk of media). I have looked at the motherboard and cleaned the motherboard to remove any possible dust/contamination and cannot get good performance from any floppy drive.Context, since it's not spelled out with a lot of background in the article: most floppy drives spin at a fixed RPM, which is referred to as a Constant Angular Velocity (CAV: ie, no matter how far out on the disk you are, the disk rotates by a constant angle per second). The SCSI2SD drive always boots to System 7.1 fine and reading and writing files to the SCSI2SD drive works fine without errors. Has anyone had a similar issue?I am thinking that my SWIM chip is bad. I have even tried a FloppyEmu as the internal drive and as an external drive and get the same errors.
I have tried a second 1.44MB disk drive and get the same errors. When I try to format a 1.44MB disk I get an Initialization Failed error. I can sometimes read an application or formatted disk, but most times after opening a file or writing a file to the disk the Finder shows an error that the disk "" cannot be found and the disk icon disappears from the desktop while the disk is still in the drive.
I have a 1.44MB superdrive as the internal floppy drive. I have a Mac SE/30 with Rominator II and SCSI2SD drive.
