Disabling SCSI parity checking to dump disk on ACB4000 MFM-SCSI adapter?

[dave.g4ugm at gmail.com]

Gentles,
As its really an MFM Disk why not read it with an MFM adaptor? Something like:-

https://www.pdp8.net/mfm/mfm.shtml

which will read and image MFM disks and replace them. Expensive perhaps, but perhaps some one can lend you one to get an image...
... or if the SCSI <=> MFM adaptor supports two disks the use a DREM

https://www.drem.info/tech-info

and perhaps DD to copy the data.....
