How do you hook a third drive up to an Amiga 500? I have all of my ports filled with DigiView hardware, a modem line and my second drive cable. Isn't there a way to link from drive to drive to computer? If so, do I have to reorganize my startup-sequence? Any help? -Steve M. Suhy

Don't do this without another power supply. Don't do this without another power supply!!!! <P-P-P-_PLEASE!> You run the *extreme* risk of doing damage to your 500.

Just buy one that has a pass through (the A1010 does and so do most others) and plug the 1010 or whatever brand you purchace and plug your existing drive into that one. The drive will be mounted automagicly and you don't have to do a thing. I think I may have just mis-read your meaning about your external drive because I have never heard of an Amiga drive with no pass-through. Oh well, hope this helps! Ian Smith <ims103@psuvm.bitnet>

DPaint III doesn't even have any recognition of the current directory, requiring you to go through hoops to get where you already are. It would surprise me to no end if they ever come out with a decent file requester. > I doesn't even access when I cold boot! Do I need >more power? As in power supply? Not necessarily more power, but perhaps just power. Not all external drives pass the 12 volts through to the next in line. You could try swapping the order of the two external drives to see if the other one passes the 12 volts. You could try adding the power passthrough yourself. If you go for any of these, you can then see if you have enouh power. Sometimes you will, sometimes you won't, it depends entirely on the power supply and A500 _you_ have. The best all around is to power the drive externally. -larry -- This life is a test. It is only a test.

Other responses have explained the mechanics of a three drive hookup. As for the danger of damaging your computer, the main danger is to your power supply, and that's less than $100 to replace. According to the estimable Chuck McManis, > "What is the worse that could happen if I tried this to see if it > will work?" Then the answer is a simple, the system won't boot in > the worst case, and will crash more frequently in the common case, > and will run fine in the exceptional case. I have heard from half a dozen persons who have added a third drive without problem, and my system is working fine with three drives (so far--it's only been two weeks). I had no reports of trouble. But: > C/A may have (I believe they do) several suppliers for power supplies, > and there are variations within the same power supply manufacturer's > units. So if you find that your system will handle it, you can't > generalize that to another system. You're more likely to have trouble if one of your external drives is an old A1010. Some machines won't boot with an A1010 as DF1, but will if it is moved to DF2. And, of course, you're more likely to smoke your power supply then if you use two late-model drives. For a little insurance, I took apart my power supply (four #1 Phillips screws in wells on the bottom), blew out the dust, inspected and reassembled. Then I built a wooden platform to give it more clearance underneath for air circulation. Probably a waste of time, it didn't run hot before and it doesn't run hot now. When buying a drive, look for a connector that passes the power and a switch to take the drive out of the circuit without taking off the cable. ****** WARNING ****** And as the mighty wizards were careful to tell me: nobody promises that this will work. If you destroy your computer, it comes out of your pocket.

Probably better get an external 12 volt supply and add to the 2nd external drive if you have a 500. I am running two externals (home build) using the internal supply of the 1000 with no problems. -- _____________________________________________________________________________ ____ ____ ___ Earle Ake /___ /___/ / / Science Applications International Corporation ____// / / /__ Dayton, Ohio ----------------------------------------------------------------------------- Internet: fac2%dayton.saic.com@uunet.uu.net uucp: uunet!dayvb!fac2

[lazy today] I run an A1000 with an A1010 and a CA-880 drive. No problems. I have the A1010 hooked to the CA-880 because it has a longer cord. Dana Bourgeois @ cup.portal.com

Please be aware that the A1000 power supply
has a lot more reserve than the A500's.
