I'm a neophyte to hard drives, so skip this article if you're tired of answering the same beginner questions all the time. I'm interested in getting a SCSI drive. Someone told me that drives with 25 pin connectors need controllers while those with 50 pin connectors have the controllers built in. This sounds fishy. I thought all SCSI drives had controllers--that this was part of their attraction. Which is the case and what is the deal with the different # of pins, anyway? Assuming all SCSI drives have controllers, would a cable be all that is needed to convert between a 25 pin host adapter and a 50 pin drive, or vise-versa? Exactly what is the role of the host adapter (I do have a vague idea)? Is it the host adapter that determins how many SCSI devices can be connected (I've seen 7 and 14)? Thanks a great deal. Email would be much appreciated by me and probably those who are sick of hearing about this. ======================================= = Simon Rademacher = = rademach%tramp@boulder.colorado.edu =
