Strike that. New CF is now throwing an "Error 4 in drive description" when clicking on "Read configuration". Previously this had worked several times. No other changes to hardware or cabling and all other SCSI devices working correctly. Tried to format the card on my PC and brought it back over to my Amiga to see if that would make any difference. Nada.
Screenshot attached, but I think I should cut my losses and just try using a different card. So much for all those positive reviews on amazon! 
sounds like you got a bad card or a counterfiet. i usually buy sandisk from newegg and have never had any trouble. i use the ultra and such pretty much exclusively.
I use sfs 1.279(sfs/00) for all my stuff though.
One thing you can try,and i cant recall if it makes a difference,but try formatting in the pcmcia to cf adapter in the card reader.
Oh and dont use hdinsttools
