thats a good thing then. OS9 has/had a hard time with switching drives between different models of macs-it installed too many machine-specific files. os x, however, does a universal install, so everything should be there for all supported machines. therefore, i would suspect that it is a jumper setting on the drives that needs to be corrected... http://docs.info.apple.com/article.html?artnum=86150 make sure that the jumpers are all set to "CS" or "cable select" and that the boot drives are connected to teh end of the ata cable (thusly, "cable select" will recognize it as master) also make sure that if you have multiple drives on the same ata bus, they are all set to cable select. hope this is some help.... sandor On Thu, 23 Oct 2003, Jim Robertson wrote: > On 10/22/03 8:23 PM, "sr ferenczy" <srf7425 at rit.edu> wrote: > > > quick question- OS X or OS 9? > > > > sandor > > I'm sorry; both machines are OS X 10.2.8. > > Jim Robertson > -- >
