Not so on the 34 spt only. What you should do is add jumper W8 to the 1007a.
 This will put the controller into a WD1005 compatible mode. (Except , contrary
 to what most WD people will tell you, it WILL handle a 1:1 interleave). The
 WD1005 compat mode handles 36spt just fine and will increase track buffering
 performance as well as slightly increase your drive space. Three hints :

	1) Don't use the Interactive formatter as this is just for ST506 drives
	2) Get the WD formatter to show the correct spt.
	3) Don't answer yes to the alternate sectors question.
