Out of curiiousity I went thru the filesystem/partiton config on my A4000/CS MKIII/OS3.9 machine running a real SCSI hdd on the SCSI bus on the CS MKIII.
I am using the PFS3 filesystem, version 18.5. I set up this system over 15 years ago and have forgot what motivated me to put the current values for maxtransfer, blocksize and buffers.
I have maxtransfer set to 0X00FFFFFF, is that the correct value for this hardware/filesystem setup?
