![]() ![]() The guys hooked their scope up and used Greaseweazle to attempt to read the disk, but captured the disk data directly from the drive. There was a second disk that was in even worse shape for no apparent reason. The actual media had a small dent in it.įlattening the dent didn’t really help. Looking on the disk, it was easy to see why. At that point, the clocks degenerated into noise. The disk in question looked good with reasonably clean timing clocks except in the area of one sector. Greaseweazle provides a nice display of read sectors and shows timing coming from the floppy read head. ![]() Time to break out the oscilloscope and read the disk manually, which is what they did. The problem is that Greaseweazle couldn’t read the disks due to CRC errors. They turned to Greaseweazle, an interface board that can dump just about any kind of floppy disk if it is attached to the right drive. and needed to read some disks that reportedly contained source code for several BBC Micro games, including Repton 3. There’s a lot of data on magnetic media that will soon be lost forever, as floppies weren’t really made to sit in attics and basements for decades and still work.
