Issues reading and writing SCP files to 640KB CP/M disk about greaseweazle HOT 2 CLOSED

Another piece of information -- Track 0.0 is IBM.FM, 128 bytes/sector, 16 sectors, 125 kbps. All the other tracks (including 0.1) are MFM. Kind of like an Olivetti M20, but maybe a little different because first sector starts at 1, whereas if I'm reading diskdefs right, first sector on the Olivetti M20 starts at 0.

The following diskdefs will work with it for reading, but suffers similar issues as the raw scp file when attempting to write, including an inability to verify:

disk ipds
    cyls = 80
    heads = 2
    tracks 0.0 ibm.fm
        secs = 16
        bps = 128
        id = 1
        rate = 125
    end
    tracks * ibm.mfm
        secs = 16
        bps = 256
        id = 1
        rate = 250
    end
end

Okay, I feel like an idiot... I didn't have the write jumper installed in the greaseweazle. I was reading back the original disk (which happened to be a reused DOS disk).
