I run several (8) SCA drives (9 gig Seagates), but I have only been sucessful at running one as an internal device. This may be a pain, but I have most of them in an external box with an external terminator on the end of the chain. For some reason I have not been able to get them to work any other way. The internal one (in a 7500) has a terminator on the end of the ribbon cable as well, but this required a new cable to accommodate the terminator and both drives in the 7500. The S900 has enough plugs you probably shouldn't need a longer cable unless you have it "loaded." 8^) I just got my S900 back today after it was on loan for over year. I tried to put an SCA drive in it but couldn't even get it to spin up, altho the LED on the drive did flash. I ended up putting another drive inside and when I hooked the SCA drive up to the external bus in an externally terminated box, it spun up just fine with no change of settings on the drive or the adaptor. It will also boot from it that way, though it was virtually dead as an internal device. I don't have another internal terminator. > I see the eight pins for the jumpers with > ID0, ID1, ID3, No ID2? These are the SCSI Address IDs. You place jumpers on these to give the drive a unique address. Assuming you have no other drives on the bus and that your CD drive is #3, then not jumpering any of these pins or placing one on 0, or 1 is fine. If you have other devices, internal or external, check your System Profiler for available settings and use jumpers in combinations to get the required unique ID. I don't think you can use the ID3 jumpers on your computer unless it's possible when you add the card you mentioned below. >There are four shiny steel pins in a white > plastic box on the > left side of the back of the SCA Adaptor You plug power into this plug.

This adaptor adapts SCA 80 pin connectors to EITHER 50 OR 68 pin cables. > I don't really understand any of this.

In fact, while there may some jumpers you don't want to remove from the drive, any function you can do on the adaptor may be better done from there. I'm not really sure if setting the adaptor to a setting different from those on the drive would cause a conflict or not, but I KNOW that using the adaptor to set SCSI ID works without further ID jumpers on the drive. > Is a fan an absolute for this drive > alongside the regular SCSI > Drive in the S-900? I guess it would depend on how hot it gets. I think there's a fan cage in the bottom of the case. I haven't spent a lot of time in there, but there may be a way to attach a drive there too. If not, you could devise a bracket of some sort for mounting it down there and screw it in like I did to my "freebee" PC which hasn't been used since I flashed my Sapphire. 8^) Steve ===== Steve Hardy __________________________________ Do you Yahoo!?
