the Gesswein MFM emulator was able to capture a flux transition dump! i used their mfm_util to analyze it, and it is a very odd format: check out the command line: --format EC1841 --sectors 32,0 --heads 4 --cylinders 153 --header_crc 0x0,0xa00805,32,4 --data_crc 0x0,0xa00805,32,4 --sector_length 256

@tubetime@mastodon.social Try SpinRite 6.0 that will fix it right up.

@tubetime@mastodon.social Don't feel bad. I had a Data General Nova at work that I used to collect and process data from flight testing. One day, the machine made a sound like bad brakes. I asked one of the admins, who said, "Oh, yeah. That happens from time to time. We always lose a bit of disk space when that happens."

@tubetime@mastodon.social "sounds bad"? That's exactly how I remember the sound of my 20MB Seagate MFM drive spinning up. Suddenly transported 40 years back by hearing it.
