Mac OS 7.6's Drive Setup IDE drives = failed restarts?: a follow-up

Regarding the report last time that updating with Drive Setup 1.2.2 may cause startup problems with Macs that have IDE drives:

Many users ofvarious models of Performa Macs and PowerBooks that use IDE drives reported no problem with Drive Setup 1.2.2. One especially notable exception was Scott Lewallen, who had this problem on 4 different Performa 5260/120 models. Reader Steve Hyman claims that the problem may indeed be largely restricted to PowerBase clones from Power Computing.
