simple A1200 HD question
« on: April 21, 2003, 08:20:53 PM »
Although I haven't done it before, its got to be one of the easiest operations ever (not as difficult as setting up a probe station for leakage current measurements on 300um solid state detectors anyway!)... I'm starting to wonder if the HD is **cked

I take apart the A1200, and carefully lift the k'board. I put the 2.5" HD on the mounting bracket and carefully plug it in to the pins on the mobo. I plug in a PSU, switch it on, and......nothing, no LEDs on the miggy, no floppy drive clicks....
Hmmmm....
I then plug in an A500 PSU, thinking this might solve the problem. Power up, and.....nothing...:(

How do I know if the HD is 'ked or not? It came all nicely boxed in an antistatic bag with a load of Amiga gear I picked up. Or is there something I have overlooked?

Any suggestions greatly appreciated

Does the Amiga work without the HD installed?

Yes, I've taken the HD out and it works fine!

Not much to overlook on this one...  Pretty obvious things.  Make sure your hd isn't shorting a power lead against a ground.  Make sure you have the ribbon cable connected to the proper pins on the HD (not reversed or offset - the cable for a 2.5 has power running in it - a failure here could be very bad!)
Make sure the cable is good.  That's about all I can think of.

Finally, if you can, test the HD in a laptop.  

The stock A1200 PSU should be enough to at least spin-up an A1200 with hard drive.  (It might have heat problems after hours of use, though.  The A500 PSU should be plenty sufficient for an A1200 with baseboard and HD.)

It sounds more sinister than a power problem, I ran an 030 & HD off a standard A1200 psu for years without a problem...

What I'd do is open up my stepdad's laptop and swap drives, and see what happens  :-)  or put it in another Miggy?

Also some IDE cables are modified so that not all the pins are connected. I can't remember whether or not 2.5" IDE cables are keyed or not, but if the cable's the wrong way round that could be a contributing factor... :-)
