Iain, You're not using the stock 1200 power supply for that beastie are you? That's a lot of a load to stick on the stock power brick. Try a Bigfoot supply if they have a U.K. version… or even a 500 power supply. I've seen similar problems with loaded 1200s. In one case, the power supply was marginal- it would kick out periodically. Not enough to reset the computer, but enough to spin down the drive. The "boiing' sound could be the drive spinning down. Also, I think some of those 2.5" drives have an idle spin down, for battery saving in laptops I guess. If it's been idle for a while, it will spin down. Then when you go to access it, it trys to spin up. That's a heavier load on the power supply than just running, so it will aggravate a marginal power supply situation. That's my thought, for what it's worth. -jim MOS via Autopilot & Amiga

My A1200 is pretty loaded as well, and I am using the A1200 brick. I have a CSA 12guage 33mhz w/MMU, FPU, and SCSI, with 8MB Fast RAM and an internal 120MB Conner drive and an external Quantum 540MB drive (On its own power). I have no problems with loss of power, but heat is a different story 🙂 — Dogs crawl under Gates, Software crawls under Windoze — Rick Green via AutoPilot 1.74

Amazing…. but as they say it the ads, "Your mileage may vary". It's als possible you recieved a 500 brick instead of the 1200 version. Some 12 saw came with the heavier 500 power supply. Strange that the 500 supply would ever be considered "heavy duty".

Really? I thought the A1200 Power brick was supposed to be the more heavy duty. I have an A500 here as well, maybe I'll see if it's brick will power the A1200. The A500 has a lot of stuff on it, too, but most of it's stuff is self powered. The only thing drawing from the brick is the MMR '030 33mhz and 2MB 32bit ram. The external bus expansion, etc is self powered. — Dogs crawl under Gates, Software crawls under Windoze — Rick Green via AutoPilot 1.74

It's been a while since I saw a 1200 brick, the one I'm trying to fix came with the 500 supply. The 500 brick is rated at 4.3A on the 5v and 1A on the 12v. The 1200 brick – it's the same white color as the 1200- was about half that, if memory serves. I'd have a reluctance to experiment though, given the vast supply of spare parts for the 1200… 🙁 -jim MOS via Autopilot & Amiga

You're right. Looking at my A500 power supply, it reads 4.3A on 5v and 1A on 12v. The A1200 power supply reads 3A on 5v and 500mA on 12v and 100mA on -12v. I've never had any power problems from any of them, though 🙂

You like that tag line, huh? Found that one on Fidonet. Quite a few interesting ones lurk there 🙂 — Dogs crawl under Gates, Software crawls under Windoze — Rick Green via AutoPilot 1.74

JIM, That's a fascinating reply. I have never had this problem before and I have had this setup for awhile. What I'll do is remove the M1230XA and run various programs that can run inside the 2Mb and see if the problem reoccurs. I already have an upgraded power supply – not bigfoot though, but one I got from a UK company. The problem also occurs sometimes when I switch the computer on with the hard drive light not even coming on and I end up with the little WB3.1 insert disc animation. I switch off and restart and then I get the hard-drive going. I'll let you know how this goes. IAIN. CALLING IN FROM SCOTLAND ON A 68030/50/50 AMIGA1200! ON AUTOPILOT 1.72

Iain, Well, it's certainly possible you have a marginal hard drive. It's just a lot easier to swap out a power supply for testing than a hard disk. If you've been running with this configuration for a while, I would tend to suspect the hard drive. It's failure to spin up from a cold start would also point to the drive. It's still worth trying another supply, or reducing the load. Power supplies have been known to fail also. Good Luck, Jim Autopilot & Amiga
