8-bit acorn emulators • Re: B-Em

I have a shiny new Greaseweazle and a grubby old Master Welcome disc (ADFS "S" format), which I've read:

Code:

gw read --drive=0 --revs=1 --tracks=c=0-39:h=0 beeb40.1.hfe::bitrate=250
The resulting HFE file works in a Gotek plugged into a real Master 128, and beebjit can read it. But b-em is not happy:

Code:

hfe: drive 0 reporting bad clock data at bit position 6823 of track 0hfe: drive 0 reporting bad clock data at bit position 18215 of track 0hfe: drive 0 reporting bad clock data at bit position 23911 of track 0hfe: drive 0 reporting bad clock data at bit position 29607 of track 0hfe: drive 0 reporting bad clock data at bit position 40999 of track 0hfe: drive 0 reporting bad clock data at bit position 46695 of track 0hfe: drive 0 reporting bad clock data at bit position 52391 of track 0hfe: drive 0 reporting bad clock data at bit position 58087 of track 0hfe: drive 0 reporting bad clock data at bit position 63783 of track 0hfe: drive 0 reporting bad clock data at bit position 69479 of track 0hfe: drive 0 reporting bad clock data at bit position 75175 of track 0hfe: drive 0 reporting bad clock data at bit position 86599 of track 0
And round again several times.

Is it a bad HFE the others are being lenient with? Have I captured it wrong? It b-em being too stringent about something?
