I've had this sort of thing happen on MFM, RLL, and a SCSI drive
as well. 

Its as though there was a poision.pill out on the disk left by
the previous installs... but that doesn't seem to be it
either in that once this has started to happen, even re-doing
the low level format, formatting the RLL to MFM and then back
to RLL and so on doesn't clear the problem. 

I gave up when a disk died and I got one that was big.enough
for the job. Had that not happened, I probably would have 
started taking a hard look for problems with the install
floppies... but those same floppies worked find for building
filesystems on drives that had not taken this 'hit.'
