im looking at getting a fastlane z3,i have no idea about scsi, and need help
so I install card and connect to a http://www.ebay.com.au/itm/361068897384?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 with a 50-PIN SCSI CABLE 3 x FEMALE PORTS to a 80-pin sca scsi drive(looking at a http://www.ebay.com.au/itm/151568121163?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 and that's it?? or do I need to put a http://www.ebay.com.au/itm/301123617020?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 termination???

It depends on whether those SCA-80 adapters have termination on them or not and what type it is. For SCSI-II Fast which is what the Fastlane supports, you need active termination like the terminator you picked is. However, this is where it sort of depends on how you're going to connect them up. If you're doing that internally then you could use that terminator on one of the HD-68 connectors on your last SCA80 drive, though it might not fit so well. You also want to put a terminator on the external connector, the Fastlane has three resistor nets next to the internal SCSI connector, if those are missing you will need to terminate the external port of the Fastlane. SCSI is always Terminator=====Device=====Controller=====Device====Terminator. Sometimes a SCSI controller has termination on it that you turn on or off or does it automagically as needed.

"use that terminator on one of the HD-68 connectors on your last SCA80 drive" ?? isn't there only 80pin connector on sca80 drive?
I want to use the ide for cd-rom drive,then from the fastlane z3 to a scsi hard drive??
so fastlane to sca80 adaptor plugged into scsi hard drive with 50-pin cable???? need termination thingy????where lol
and yes all internal in a a4000 desktop case

If you look at the adapter you linked, it has a 50 pin and a 68 pin connector on it. I was saying you could use the 68 pin connector on the last drive of your chain to terminate it, if the adapter doesn't provide termination on its own. Also... I would carefully monitor your system temperatures if you're putting in 3x10000RPM drives in it. Those drives get hot! I don't know about the particular drives you're looking at but usually 10000 and 15000 RPM drives specify they expect you have a large fan blowing on them. There is a utility on aminet to check SCSI drive temperatures, I think it's just called SCSI thermometer I would suggest using that regularly to make sure you don't cook your new drives. Actually just get a 300GB SCSI drive and be done with it rather than put 3x68GB drives in a desktop case.

It's pretty obvious if your Fastlane has the termination resistors in place or not.

Right next to the internal SCSI connector there are three (blue in my case) 2cm long flat things with 8 pins each. Those are resistor packs.

If you have those, you're terminated on the card end. If you see 24 little holes to plug them into, you're not terminated on that end.

You only remove those if you're going to use the external SCSI connector AND internal drives. For example, a scanner or external drive enclosure. Then you terminate after that external thing.

You still need something on the other end of the cable though, AFTER the drive. Terminators go on each end, NEVER in the middle.

You won't fry anything, but you will pull your hair out looking for the problem. Missing drives, slow transfers or lockups at best, data corruption at worst.

BTW, I'm using one of those drives in my Elbox tower and it's hot enough that I put a fan under it to be safe. I just rigged up a 80mm case fan with some zipties to keep the air circulating.

In a 3000 or 4000 desktop you may have to get really creative to keep that drive alive.

To get the best speed out of the card, make sure you read the manual and set the jumpers correctly.

I also used HDToolbox to get it up and running rather than their tool so that I could access the whole drive, then used the utility from the disk to enable synchronous transfers.

Once you see that it's set up well enough to handle synchronous transfers and still be stable, you can add it to your startup sequence so that it happens automatically each boot.

There may be a better way, but it worked for me. I tried using their tool just to set the Synchronous flag in the RDB, but had problems that I can't remember. (sorry)

Those Fastlanes are notoriously picky about the computer it's in, so be prepared to swap it into different slots and curse a lot.
